SCP Foundation/Nightmare Fuel

Please add new examples to the bottom of the page.


 * The real crowning piece of terror inherent to nearly every single SCP object page: before you even get to the description, you get one or more paragraphs describing the special containment procedures needed for each object, forcing you to imagine just what requires this kind of containment process. These procedures often include battalions of elite commandos with assault weapons and body armor, 3-meter-thick titanium cubes, on-site nuclear self-destruct systems, deep underground or undersea locations, overwatch from AC-130s, unimaginably extensive monitoring equipment, people with unusual skills or attributes (such as fluency in Ancient Sumerian or a "marked sexual deviancy"), vats of hydrochloric acid, bulletproof glass, and other SCP objects. In other words, stuff that no government in their right mind would ever authorize. It's around then that you know what you're dealing with.
 * SCP-579 combines this with the tendency to censor the documents to truely scary effect. Its classification is Keter (objects of the worst sort), and considering the extremes to be gone to in the case that anything happens in its containment cell, it can cause ... something very bad. But everything but the containment procedures were removed by High Command. so noboy but the seven survivors of... whatever know anything about it (and "termination of agents to prevent data leakage" might have been used if there had been more)
 * The sheer knowledge that if it wasn't for the Foundation, the world might have ended already. Also, the sheer knowledge that despite the existance of the Foundation it just might end anyways, since several objects that could cause The End of the World as We Know It require only one tiny slip-up to activate, and there are several others the Foundation cannot do anything about.
 * SCP-583. Good luck watching Sesame Street again.
 * SCP-280. It attacks people and rips them to shreds... for no reason.
 * SCP-173, the statue that tries to kill you if you break eye contact with it.
 * Enlarge that page's picture to get a better idea.
 * 173 appears to be the only thing 682 is afraid of, as when it was locked inside 173's chamber its first response was to huddle in the corner farthest from 173 and stare at it without blinking for several hours. When snipers popped 682's eyes from afar, it responded by growing bullet-proof eyes all over its body so that it could keep 173 from getting close to it. However, 173 did some damage to 682 before it could adapt, but was unable to destroy 682.
 * For extra nightmares, think on this: As long as you look at it, it's a harmless statue with entirely curved edges, no claws or anything, made of concrete and rebar, so it shouldn't be able to move. So... what is it when you're not looking at it?
 * Also: this short story. What would happen if said statue replicated. Exponentially.
 * Said entry describes 150 SCP-173s attacking and ripping apart SCP-682. The fucking indestructible lizard.
 * This video. The statue in action.
 * SCP-232 falls into a similar vein. It's a statue of a Sumerian goddess that will cut you up if you allow any shadows into its constantly-lit containment area.
 * Also: When SCP-173's picture was taken with SCP-978, there was no change. Pictures taken with SCP-978 show what the picture's subject wants to be doing at the time of the picture, which means SCP-173 is exactly where it wants to be.
 * The alternative is that SCP-173 is not sentient. Perhaps a construct created for killing?
 * This comic. Nothing Is Scarier until it's smiling on your face.
 * In the game "Containment Breach", you have to run away from it, among other SCPs. And if you encounter it, and you close a door in between SCP-173 and yourself?.
 * SCP-106 "The Old Man". An entity resembling a rotting old man. It causes severe corrosion and decay of whatever it touches. It drags its victims into its pocket dimension (which it seems to have complete metaphysical control over) and slowly tortures them for hours or days, before ejecting their mutilated bodies back into this world. Take a look at the page pictures. As if that wasn't enough, it's completely indestructible and almost impossible to successfully contain.
 * The procedure for its recapture is, if possible, more terrifying than it is. Namely, taking a human in it's preferred age bracket and injuring them by breaking a bone or cutting a tendon, placing them in a cell, and broadcasting their cries to lure in SCP-106. If SCP-106 isn't taking the bait, additional damage is inflicted. If it still isn't working, more "prey" objects are brought in.
 * SCPs 076-2 and 682. Both are indestructible, very sharp killing machines. Sure, you can put them down for now, but they'll just come right back again in a few minutes.
 * SCP-076 has a long description on its page about how in "the worst breach to date", its containment site was forced to set off a nuke, killing everyone and incinerating the location... and failing to kill the SCP.
 * SCP 682 is described as a reptilian monster able to mutate and regenerate body parts, with hyperintelligence, and a hate of all forms of life, and the ability to adapt to anything. It's still capable of talking (usually in the form of obscenities and threats) with as much as 80% of its body mass destroyed, and needs to be kept in an acid bath so as to constantly keep it weakened. What makes it worse is the fact that they have to experiment with other SCPs to try and find away to permanently destroy it. The most frightening thing? It usually fails, and then it becomes immune to whatever they tried.
 * How about the interaction between 682 and 826? 862 is a pair of pewter dragon statues that transform the room it's in into the setting of any book placed between them. If the people fail to escape the room, they will lose all memories of their past lives, and the story will rewrite itself to incorporate them. Realizing this, the SCP wrote a 12 page short story called "The Generally Nice, Friendly Thing That Can And Will Kill SCP-682 Permanently if it So Much As Spots That Damn Lizard", that was just a description of a plain green field, and a large monster whose sole descriptive quality was the stated ability of permanently killing 682. So, they put 682 in there, and in a matter of minutes, the plain green field turned into a scorched crater-filled wasteland, and the 12 page short story had become a 1,000+ 209 page epic called "The Generally Nice, Friendly Thing That Tried To Kill SCP-682 Permanently But Failed" describing the epic battles between this monster and an innocent creature whose very existence was based around its ability to destroy 682. And 682 won. Poor thing.
 * Yes, that's right. They wrote a story about something that specifically could kill 682, and 682 killed it. That's how unkillable the bloody thing is.
 * That's actually nothing compared to the attempt using SCP 563. They reduced it 'to 1% of its body'' by changing the fundamental natural constants. AND IT RECOVERED AND EVEN SEEMED TO ENJOY IT!
 * What makes it worse is SCP-343 will not get near 682 and calls it an abomination.
 * Dr Gears, 682 creator, says that, in his view, 682 wants to kill everything because, through his eyes, life on this reality is so utterly wrong, disgusting and frightening to him that his only response is to destroy everything. It makes you wonder just how his homeplace looks like...
 * And SCP-053 likes the thing! It even seemed to like her back, actively trying not to scare her when they first made contact and even letting her draw on it with her crayons. Although SCP-053 looks and acts like a three year old girl, everyone over the age of three has an irresistible desire to kill her after ten minutes of exposure, and everyone who tries dies painfully. Perhaps SCP-682 feels the same way about humans as humans do about SCP-053. In which case, one wonders where 053 really came from...
 * SCP-689, which will not only kill you if you break eye contact with it, it will teleport to you, and anybody who sees it now will also be in danger of death.
 * Then there are more subtle things, like the turnover in Class D personnel.
 * Not to mention, the implication that some Class D personnel are hired as Schmuck Bait, with the full knowledge that they'll ignore their orders and do something stupid... just so that the scientists will see what happens.
 * SCP-882 is a clockwork... thing that grows by absorbing all nearby metal objects and can brainwash anyone nearby into "feeding" it. SCP-271 is an engraved coin, whose inscription spreads to nearby objects and turns them into an indestructible metal with unknown properties. Accidental tests on living organisms suggest that both being absorbed by the machine and being converted by the coin are excruciatingly painful. There is an obvious reason these things are not to be allowed in the same room. The Church of the Broken God wants to try it out.
 * SCP-002 is a ball of flesh with a door in it. Through the door is a modest apartment, complete with furniture made out of the body parts of the people it's killed.
 * The old SCP-112 is an Artifact of Doom activated in the presence of any non-virgin or non-castrated person. And it has been stolen by radical Muslim terrorists. Get the idea?
 * SCP-415, The Harvested Man. Exactly What It Says on the Tin.
 * SCP-231-07, a girl of undefined age who was impregnated with some kind of Cosmic Horror by a Satanic sex cult. The only way to keep it from being born is by putting her through "Procedure 110-Montauk" every twenty-four hours, which is described as involving "brutally (DATA EXPUNGED)". It can only be carried out by convicted sex offenders among Class D Personnel, and is being supervised by employees who have passed a psychological examination in which "mild sociopathic tendencies and marked sexual deviancy are not to be considered automatic fail conditions" (an early warning and implication of who carries this out), and it's 10 times worse than whatever you think it is.
 * Here's one bit of extreme Nightmare Fuel relating to SCP-231: Some of the staff who were involved in the project have taken amnesiacs to forget it, and false memories have been implanted. Which means that you could have been on the project and not even remember it.
 * Oh, and they started using amnesia-inducing drugs on 231 herself; the sum total of 110-Montauk was starting to induce a form of shell shock in the victim. As a constant level of agony and terror needs to be inflicted to suppress the Eldritch Abomination, they started wiping her mind of her knowledge of Montauk. Eventually it was determined that a weekly dosing cycle was most efficient, as the 3rd to 4th time is the most mentally devastating; the first time is horrible, the second time establishes a pattern, and the third confirms that this is what the rest of your life is going to be like.
 * The article contains an addendum added by one of the heads of the SCP foundation specifically stating (presumably to set straight employees having second thoughts about all this) that while "Procedure 110-Montauk" is quite possibly the most horrifyingly evil thing the SCP foundation has ever been involved in, failure to carry it out will result in the Endofthe World As We Know It, judging by the death tolls that ensued when SCP-231-01 through SCP-231-06 gave birth. Sweet dreams.
 * The specific age of SCP-231 is not specified, only a minimum and maximum, both of which are censored in the article. But the minimum is a single-digit number.
 * In such fine print that you may have to View Source to find it:
 * Alternately, imagine being part of the support staff for the 231 containment site. Knowing what you're ordering done to the girl, watching it every day, obtaining supplies and materials to enable it, terminating anyone who tries to stop it. There's a reason why so many people associated with this thing commit suicide.
 * One of the most disturbing things about the SCP series is that almost all of them were located and contained after coming into contact with a regular civilian human being going about their business, with no knowledge of what the thing is, how it works or where it came from. Consider that there's an indeterminate number of supernatural objects that could qualify as an SCP scattered around the world, and you could run into, say, an undocumented Keter-class at any minute during your daily routine.
 * Even the joke SCPs are creepy. Take SCP-000-j, for example. It's a catalogue of every SCP item, which anybody can apparently order through a simple phone call as if they were everyday items. When one of the testers did call and order one of them (a safe-level item), it disappeared from its storage and mysteriously got delivered to his office, and the amount he would have paid for it vanished from his next paycheck. Now imagine somebody finding this catalogue and ordering one of the Keter-class items...
 * What some find most disturbing isn't that they'll do things like what they do to poor 231-7, though that's quite sufficiently disturbing. It's how they treat people who qualify as SCPs, essentially imprisoning them for life without trial, without charges, and in at least some cases, with no evidence at all that they're dangerous or likely to become so.
 * The termination log of SCP-316-D is absolutely horrific. Even though he seems to be one of those Gary Stus that pretty much psychically forces you to like him, Surveillance Log x316███ was just gruesome. Also: The thought that he could wake up on a space probe en route to the sun is what most everybody's worst nightmare is made of.
 * SCP-001 is generally reserved for the largest and most brickshittingly terrifying SCP concepts, so much so that the users of the site would rather not ruin the mystery by having a single canon SCP-001.
 * The SCP-001 proposal page itself. "SCROLLING DOWN WITHOUT PROPER INNOCULATION WILL RESULT IN IMMEDIATE CARDIAC ARREST FOLLOWED BY DEATH." What makes it worse is that the image is designed to kill you. Now if that were an SCP, and it could spread...
 * One of the possible SCP-001s. Completely harmless by itself. Its just a sheaf of stapled papers containing detailed reports of the SCP items... except that every time you look at the report, the report is on a new SCP item, which then appears somewhere in the world. Let the sheer terror of that concept work its way into your brain.
 * One of the other possible SCP-001s is a huge humanoid figure standing in front of what is more or less the gate of Eden. Getting within 1 kilometer of it will get you not only killed, but wiped from existence. If it ever goes active, The End of the World as We Know It will ensue. Making matters worse is that the page includes a transmission from Twenty Minutes Into the Future about SCP-001 waking up and bringing about said apocalypse. Mega-gulp.
 * שמע ישראל יהוה אלהינו יהוה אחד  Translated: "Hear, O Israel: YHWH is our God, YHWH alone."
 * Another concept for SCP-001:
 * Another recent possible SCP-001: a large onyx gemstone with an infinitely fine fractal gold filigree, apparently serving as a lock for an unknown object. Doesn't really seem scary, right?
 * Bright's proposal for 001: The Factory.
 * Dr. Mann's proposal. The SCP itself is very simple, just a circular gravel path. Travel clockwise, and you move normally. Travel counter-clockwise, however, and the path appears to go continuously uphill. Even if you go all the way around to the start. The real horror comes when one reads the attached document from one of the founding Overseers.  And the scariest part?
 * S Andrew Swan's proposal is a masterpiece of Meta Fiction Paranoia Fuel. The details are so confidential that even the description has been expunged and the directives state there is no way of containing it without risking a ZX Reality Failure event (the destruction of the observable universe). No-one except the O5s is allowed to know anything about it at ALL. But there is a hidden message on the page from a researcher who worked on it and managed to escape the purge detailing it:


 * Oh, and there's more: if you enter the encryption key identifying you as an O5 member with full authorisation of the O5 council, you can read Containment Protocol ZK-001-Alpha, their final sanction against SCP-001 to be used only in the most dire of emergencies.
 * The last line in Baba Yaga's entry. Quote: "While SCP-352 prefers any type of human flesh over any other type of meat, it appears to have a special propensity for children between 0 and 2 years of age. After observation of highly elevated levels of co-operation and a reduced tendency to attack staff while consuming flesh of this type, a possible alteration in the current diet is being considered."
 * The guy who randomly teleports to alternate dimensions, including one that apparently had the Joker who was right in front of him when he turned the flashlight on. "Back so soon?" The poor lad's reaction was probably the same as yours would be. Not to mention "...the spiders...".
 * The interview log when another version of that teleporter shows up from an alternate dimension is terrifying. Basically they refuse to elaborate on which one is from the "real" dimension, to keep the other guy safe. At the end, one reveals that "In his reality, Lincoln was killed while sleeping by his then vice-president, instead of by General Lee." The interviewer responds "In our world, Booth assassinated Lincoln." The end of the article just states that "Subsequent testing revealed that SCP-507s abilities have no biological basing, and that severed pieces will still “shift” along with the main body."
 * During one of his trips to another reality, 507 arrived in what seemed to be the facility, only in a state of disuse with corpses covered in a strange, breathing mold. Further exploration revealed that possibly the entire world was covered in the stuff. Upon further inspection of a mold sample 507 brought back, it was found to be very similar to both Cordyceps Fungi (some varieties of which basically brain-wash their hosts) and a fungus produced by - wait for it - SCP 407. The Foundation consequently restricted experimentation with 407, and all known copies were terminated by "Serpent's Hand," but no one is certain if more copies may be found elsewhere.
 * SCP-294 is a coffee machine that can dispense just about any kind of liquid. If you value your appetite, do not use "joe" as a synonym for "coffee" when inputting what drink you want, especially if your name is Joe.
 * Said machine can dispense "The Best Drink Ever", which causes the drinker to become depressive and commit suicide because "everything else is just a letdown now." For more straightforward ways of killing you, it will happily dispense any kind of acid. There's a reason why they have two security guards stationed there with orders to shoot anyone who is trying to order anything other than normal drinks for research.
 * When asked for something that could kill SCP-682, the liquid was so intense it vaporized the entire site SCP-294 was in, apart from a small patch surrounding the machine. Given cases with other SCPs like this, whether it would've worked is anyone's guess.
 * Speaking of disturbing food dispensers, SCP-261 is a vending machine that dispenses snack foods that might be normal, strange or bizarre. As SCPs go, it's actually pretty fun and not too scary. The disturbing part comes as you slowly read more and more stories about what comes out of the vending machine. The first time living food is dispensed, most researchers refuse to eat it and are as distressed by the idea as most people would be. But as more and more living food items are dispensed from the vending machine, researchers get more and more casual about it, until reports of the living, potentially thinking beings only describe their flavor. As if cramming the recently dead bodies of various cute little alien critters popping out of the machine is the normal and obvious thing to do.
 * Another fun result from SCP-261 is "TASTE ME", an obvious reference to Alice's Adventures in Wonderland. It's funny, right until the part when the test subject eats it, goes into convulsions, and dies due to brain expansion. "Analysis of the cake showed large amounts of human growth hormone as well as several unidentified chemicals."
 * Something really horrifying are the products dispensed labeled FOOD and DRINK. People who ate the FOOD became emotionless and dull-witted, while people who drank the DRINK became more and more subservient. Doesn't sound so bad by itself, but think about where they might have came from, and what those products are used for there...
 * And then there's the can of "Prangles." Once you pop, you can't stop. Ever.
 * It also produced Tentacle Grape.
 * SCP-835 was a collaboration between two authors: one of them was the guy who wrote the infamous SCP-231. The other wrote SCP-682. Their goal was to create the ultimate in squicky SCPs. Some would say they succeeded. For the full impact, read the article first, then the "uncensored" version, then the "uncensored" version of the exploration log.
 * SCP-835 also serves as a bit of Fridge Brilliance Nightmare Fuel for the SCP series. Now you know what kind of disgusting, freaky things are behind all those (DATA EXPUNGED) boxes, and they're exactly as bad as you'd think. "Now we can be together, just like he wants..."
 * That adds sort of a ghoulish edge to several joke SCPs where [DATA EXPUNGED] was used for laughs.
 * And then someone went and added a picture for 835. Cripes.
 * And check out the filename on said picture: "flbalanus.jpg".
 * The former SCP-995, an object that is too mentally scarring for many to describe. At best, it's been described as an "Infinite Devil Machine." It's required to be kept in a blessed lead container full of also-blessed holy water, which turns black and darkens whatever room its in. Recorded images of it breaking out of its container show tendrils poking out of its container. Unfortunately it's been deleted due to negative ratings and changed to a device which drives people insane as it touches an electric conductor. Eventually it was deleted altogether, although the original article can still be found here.
 * It's not gone anymore. Behold the Infinite Devil Machine 2.0.
 * SCP-217 is a virus that turns people into machines. It can affect any animal, replaces organs and such with mechanical parts, and the affected creature becomes repetitive and locked in a set pattern of behaviour. Scared now? Oh and did I also mention that the Church of the Broken God wants to bring it into contact with SCP-882 and SCP-271?
 * The worst one was SCP-055. Which was also the coolest. Imagine seeing something, and not being able to describe it. It basically makes you forget anything related to it, being reduced to what it DOESN'T look like. This doesn't help either. An area that makes people gain immediate knowledge of a random subject. A man enters the area, goes into a fit, and afterwards forgets he was even in the area. Locked the memory out of sheer horror? Amnesia?
 * Someone successfully managed to make the memory wipes terrifying. Doubles, of course, as Paranoia Fuel. At any moment, you could be abducted and traumatized until you can't remember your own name or who you are. Because of something you weren't even aware of. Co-worker behaving oddly? You're screwed, buddy! Good night!
 * SCP-590--they purposely destroyed his mind, reducing him to the functional level of a three-year-old -- and for no reason other than to make him more controllable. Worse than that is reading the experimental logs of SCP-978, a camera that shows the photographed subject doing what it desires to be doing rather than what it actually is doing. 590's picture is absolutely heartbreaking.
 * SCP-093. Read the whole thing, including the test reports, in order, and then read the last link on the page. The reports themselves are creepy and unsettling, but the final report is just chilling.

"(a waiter comes in pushing a cart with a wooden box on top. The box has several slots and holes opened in it, and tubes trail out, connecting to IV bags and tiny batteries. A mewling comes from within) (The box is lifted up over a plate, put on it, and then pulled off. There is a flash of some kind of twisted, shaved animal, but then a human head appears.) (the human head is that of a man around thirty five, with thick black hair and sideburns. He has extremely pale skin and dark circles under his eyes. He is severed at the neck, which reveals muscle and a bloody hole.) Head: Where am I? Who am I?! What the hell is going- (Begins looking around and turning up, down, and to the sides) Everything seems at a weird angl- hey, what are you doing! Get that knife away from me! Waiter: Bon appétit, gentlemen."
 * There was an SCP on the original message board that was a small sphere which quite simply increased in temperature. Rising, and rising, and rising. They attempted to cool down the object by storing it with ice, in freezers, with liquid nitrogen, but that only temporarily slowed the process... The temperature just kept rising. If you have any knowledge of thermodynamics, you'll know why this is worrying.
 * SCP-899. "A psychic and telekinetic phenomenon that most commonly manifests as groups of hostile phantom children." Then they went and exposed it to SCP-573. To give some hint of how "successful" that experiment was, this is what happens when a perfectly ordinary person uses 573, and taking a picture of it with SCP-978 resulted in a [DATA EXPUNGED] and a note that "It appears SCP-573 is indeed sentient in any case."
 * SCP-604. What makes it particularly bad is that it has no apparent effect on the users, meaning they chose to use it as they did of their own accord. There are extensive records of what the thing can do, because its former owners charted their progress. And when they succeed...

Head: (begins screaming) "The image contains two (2) ADULT PERSONS standing, one (1) HUMAN CHILD sitting on a CHAIR or STOOL, and SCP-███. With 100% certainty the PERSONS in the image should have FACIAL FEATURES. With 100% certainty the PERSONS in the image do NOT have FACIAL FEATURES."
 * SCP-847. Uncanny Valley aside, the "[DATA EXPUNGED]", the attacking of all females in the area, and the victim being killed by 'massive blunt trauma' all lead to some unsettling implications.
 * There is something distinctly disturbing about SCP-914. Testing shows that in spite of its supposed lack of sentience, it seems to have a rather twisted sense of humor, and on multiple occasions the "very fine" setting, which refines something to its most perfect form, has produced a (mercifully inanimate) replica of SCP-682, suggesting that it may have a "thing" for the beast. The fact that it knows 682's "home phone number" doesn't help matters.
 * Testing of SCP-978 on SCP-914 indicates that what 914 really "wants" is to have a sixth setting on its control knob, that goes beyond Very Fine...
 * Every time someone tries to run something organic through the "Very Fine" setting, it gets all "[DATA EXPUNGED]". But some of those have rather... telling... notes relating to "cleanup," and they've banned any further attempts to use it on living things.
 * SCP-342. It takes the form of a ticket to some kind of public transit, and once you get on you can never get off.
 * "And he never returned, no he never returned, and his fate is still unlearned. He shall ride forever 'neath the streets of Boston. He's the Man Who Never Returned."
 * "...and by this time tomorrow we'll be so far away, if there's one thing that I know... yeah I know, it won't be back. Paradise Special's never coming back!"
 * SCP-400 is a phone booth that can contact anyone. SCP-519 is a phone containing a voice that is on permanent Sarcasm Mode. When they tried to ring 400 through 519, 519's response was, and I quote, "Ooooh, boy...". On the other side, 400 rang, and a guard picked it up, only to be pulled apart by an unseen force. Then there was a containment breach resulting in the entire site around being locked down and everyone terminated.
 * SCP-826 is a very ordinary looking set of pewter dragon-head bookends, but if you close the door of the room, put a book or DVD between them, and open the door, the doorway will be a portal to the world of the book or film. It seems almost to be a joke entry, with a note about a researcher who was demoted for (apparently) planning to do very naughty things to a female Disney character on a DVD. But what if you tried it with the Necronomicon?
 * SCP-701. Especially Incident Report SCP-701-19██ and that photo.
 * SCP-610: It's like the necromorphs and The Flood rolled into a single package. Squick warning, obviously; the page image is especially bad (or awesome).
 * Even worse is it`s official nickname: The Flesh that hates.
 * SCP-439: It's a parasitic insect resembling an earwig that will turn your body into its hive. It enters your body while you're asleep, and then, in a process shown to be very painful, causes your body to deform into a spherical mass while the insects eat you alive from the inside out.
 * And then there's the addendum at the end, which shows an SCP researcher operating on the "bone hive", and finding that the eyes had not yet been eaten. She shined a flashlight on them, and the eyes followed the beam. Think about the implications.
 * Dr. Clef. Even if we take everything he says about himself with a grain of salt there is a mountain of evidence in various entries, logs, and reports that suggests that he is something far, far worse than any of the actual SCPs. The fact that his head is always replaced with something else in photographs is actually one of his least disturbing quirks. And he is the guy in charge of SCP Training and Development.
 * SCP-804: A piece of "art" that, when activated, slowly but surely kills all humans and destroys all man-made works in an ever increasing radius around it. The only saving grace is that said artwork is not immune to its own effects. However, the most nightmarish element of this SCP isn't its potential to destroy the world. No, the scariest part is that, according to the former lead researcher, Dr. Sorts, the SCP has no memetic influence on people. The people who created and activated a device that would wipe out humanity did it because, in Dr. Sorts' own words, they wanted to do it. That the SCP Foundation transferred Dr. Sorts to another project and is continuing testing for a memetic component means either 1) the Foundation wants to be absolutely sure that no mind control is involved or 2) even the Foundation doesn't want to believe that there really are people in the world evil enough to murder humanity entirely of their own free will.
 * The people "evil enough to murder humanity entirely" were well-intentioned extremists, at least the original ones who sacrificed themselves. As in, they wanted to get rid of humanity because they thought it had a greater net negative than positive effect on other lifeforms. Meanwhile, the Foundation has terminated or is trying to terminate several lifeforms for the same reason (and real life humans do this all the time with diseases, though with other life the extinction we cause tends to be accidental). So when you think about it, the creators of the SCP-804 merely had the same views on their fellow humans as most humans do on lifeforms that threaten them. You could argue that the SCP-804 creators are more evil because they have betrayed their own species, if you like... or you can argue that their motivations are actually more objective, since their views on what lifeforms are more harmful aren't determined by what benefits their personal continued existence. Either way, thinking about this for long periods of time is a bit like reading SCP-079 (an increasingly rational and objective computer that nonetheless clearly hates humans, if not all life), in that it has a creepy "but what if the SCP is RIGHT?" air to it.
 * SCP-354: The Blood Pond. It's a pond in the Canadian wilderness that is full of a liquid similar to blood. Highly dangerous creatures emerge from it from time to time; most of whom have nothing in common. And according to one SCP agent, it's alive. And intelligent. And angry.  .
 * The fact that a seemingly normal human emerged from the pond at one point for ostensibly diplomatic reasons and was shot on sight probably didn't help on the "angry" front.
 * SCP-120 is a pink kid's swimming pool that works as a Portal Pool, cycling between 11 locations each time you send someone through. The 11 locations include the 5 Lagrange points. Which are in space.
 * It's a convenient way of teleporting, though, except for the Lagrange points. So they simply... cause it to cycle through them. Using D-class personnel.
 * Also, it was discovered because of "reports of missing children."
 * SCP-662 is a silver bell that summons a friendly, polite butler named Mr. Deeds, who will gladly perform required services by asked by the ringer, within reasonable limits. He'll fetch you a sandwich, but not one made of human flesh, and he'll bring you a grenade, but not a nuclear bomb. Seems fairly harmless, right?  Suddenly, Mr. Deeds doesn't seem like the nice, friendly fellow we all think he is....
 * He might very well be harmless, but read the end of the interview log, and the interrogation by Agent Graves.  Shortly thereafter, he is summoned, ready and willing to perform his duties. So, he's nigh omnipotent, willing to perform any service or retrieve any object, within his capabilities, and
 * Why can't Mr Deeds explain how he does what he does, even under torture, and why does he appear so uncomfortable when asked? The photo of him from the Desire Camera showed him exactly as he was, posing for the photo, which suggests his greatest desire is to do what he's instructed to do. Is he so uncomfortable when asked where he goes and where the items come from because he's unhappy that he's literally unable to explain, or because something worse will happen to him if he does? Also, he was disturbingly calm when offering to be fed to SCP-682.
 * SCP-597. The Mother loves you. You will love The Mother. The Mother will provide for you forever. Why this powerfully telepathic...thing... has not been terminated or even properly contained is a mystery.
 * Probably because it's Fetish Fuel for some of the Foundation's higher-ups.
 * Let's count everything that's wrong with SCP-597 or "The Mother", shall we? Well, for starters there's what it is, a massive ball of mammaries, nipples for every species of mammal, and no matter what the milk will always be perfect for whatever mammal's drinking it. Most mammals can't resist it. Bats, rodents, cats, dogs, all of these can be found sucking on the thing, and refuse to let go; it's described as being a sexual, psychological, and hunger compulsion all at once. Also, the male staff have sex with it. Regularly. So regularly in fact that they don't do anything to discourage it. The thing is always covered with slobber and semen, which D-class personnel clean. Of course, that just means they get brainwashed faster than everyone else. They also have the task of collecting the milk for study (which they often sneak whole bottles off for themselves). All staff at its facility are affected. In early stages, people who quit smoking for years have a 100% relapse rate, people binge on snacks (especially dairy products) or chew gum. So much gum that they choke on it. Later stages the behavior gets even more extreme. Formerly heterosexual woman begin to engage in lesbian sex, some men become rapists, others latch onto large breasted women as surrogate mothers. If things are allowed to progress this far, all milk samples from The Mother will be fought over by the staff. Next staff begin to regard the mother with superstitious awe, worshiping it with incense, food offerings (even though it doesn't eat) and animal sacrifice. One scientist circled every one of the nipples with a red marker and wrote the word "life" next to them before killing herself. Then they begin to revert into child like states, losing bladder and bowel control, masturbating constantly, calling it "mommy", crawling on all fours and talking like toddlers, before finally curling up and joining the rodents and bats in suckling. The milk will keep them alive the rest of their adult lives, and they will be in blissful happiness, but their muscles will atrophy, and their teeth will fall out, and they will experience digestive problems from the sudden switch to a liquid diet. There is no way of stopping this. Even if you send them away from it, the effects are permanent, and they have several data expunged section describing staff that took this mental illness home with them (including one where it was implied that a man raped and killed his own mother for "not being good enough"). The only thing they can do is constantly rotate, and kill staff members.
 * Even worse: The Mother can be destroyed, but the ones who have the authority to do so use The Mother as a sexual experience, ordering a Class D to pry them off after an hour of suckling.
 * SCP-087 is a never-ending platform staircase that resists attempts to illuminate it, and descending one flight of stairs lets you hear a child crying for help about 200 meters down. The people sent down one by one found something else instead...
 * Plus, they sent four missions down into that staircase and you can only read the first three and they get progressively worse. But after the fourth mission it started to knock on the 'door.'
 * Also terrifying are the effing pictures on the thing's page. Especially the first one. It's like one of those "when you see it, you'll shit bricks" demotivators.
 * And that's not all. If you try to upload the first image to a imagehoster (you know, to avoid hotlinking), the face in the uploaded picture is gone.
 * There is now a game of SCP-087. Enjoy.
 * It's one thing to read about the Foundation personnel doing horrible, ruthless things to contain dangerous or even "potentially dangerous" SCPs. It's not even so bad to read about Foundation personnel doing cruel and messed-up things for kicks--after all, it must take a strange, not conventionally moral person to survive working there for very long, right? But then there's examples like SCP-042 and SCP-948, where there's a very strong implication that the Foundation is containing not merely harmless but good, benevolent, mystical creatures against their will, and possibly even endangering the world by doing so. SCP-042 in particular seems to be written specifically to highlight the cruelty of the Foundation,
 * Knowing the Foundation, that "reason" can probably be summed up as For Science!.
 * SCP-948 is vaguely dangerous, but the fact that the Foundation terminates people who go feral after repeated exposure to it kinda underscores the "they're evil" idea. Being essentially uncivilized doesn't make one a danger; there's no need for it. It's also interesting that the 948's effects include the removal of mental disorders/negative emotions and the removal of traces of human civilization (or domestication, in animals). It implies that human systems of thought, language and behaviour are some sort of harmful mental aberration, at least in the view of whatever the SCP is.
 * SCP-596. That it can heal any injury would have been a great help for the Foundation, if it weren't for the fact that any physical contact with it will leave the victim permanently stuck to it and unable to move it themselves unless another person makes physical contact with the statue, killing the original subject. What's even more nightmare-inducing is that absolutely no other method can separate the two: whenever a victim is surgically removed from SCP-596, they will die and a new body will grow from the parts still attached to SCP-596.
 * What's even worse is how the Foundation takes advantage of its abilities. The victims are used as reusable organ donors. Since anesthetic isn't an option thanks to the SCP's powers, the Foundation used to resort to decapitating the victim in order to temporarily incapacitate them during the harvesting. Now they just empty their skulls to keep them from screaming.
 * Not as horrifying or deadly as the other SCPs, but SCP-613 ability to make contaminated organisms lose all color and become black and white over the course of a few days and leaving the carriers unable to perceive or remember what colors are, brought shivers to me. Luckily any healed former carriers can develop immunities to the disease.
 * Becomes a bit nicer, however, when you realise that it is a cure for the horror that is SCP-8900-EX.
 * SCP-204. 204 comes in two parts: 204-1 is a colony of nano-machines that follows around 204-2, protecting him/her from harm. 204-2 is a child aged from 4 to 14, with a history of being abused, who can control 204-1. When 204-2 turns fourteen, 204-1 finds a new child to protect, and, if the former 204-2 is mentally stable, the former 204-2 is given a Class-A amnesiac and put into a foster care program. That's not the Nightmare Fuel. The real NF comes from an addendum that explains that due to 204-1 freaking out if there isn't another suitable child to imprint on if needed, the Foundation have a group of suitable candidates. However, if they really need candidates quickly, they can enlist some more candidates who don't fit the protocol- i.e., they are of a suitable age (preferably under ten), but they don't have a history of abuse. The Foundation will then turn them over to 'caretakers' which will consist of D-class personnel convicted of violent crimes, child abuse, and pedophilia. It also says that the procedure for hiring the 'caretakers' is the same one for finding people to perform Procedure 110-Montauk on SCP-231. Jesus Christ.
 * Oh, and as an aside? SCP-204 will psychically manipulate whatever it's guarding into taking dangerous actions so it is forced protect what it is guarding, and thus allowed to feed. The SCP literally forces the child into danger so it can feed.
 * And on top of that? Right now it's guarding a complete sociopath who is very quick to threaten people with the hungry, amoral nanomachines!
 * And as if to top the whole thing off, 204 is ludicrously powerful. The initial capture required an Abrams tank and an AC-130. Yes... to capture this thing, you need not only one of the most powerful armored vehicles in the world, but also Death From Above Up to Eleven.
 * SCP-787 is rather mundane (average scenes of grisly horror and cannibalism with some poltergeist activity), but the real chiller is "TO BE SORRY" endlessly repeating on the flight log.
 * The Great Short Story Contest. Given that the contestants must include at least some of the twisted geniuses responsible for the entries above, we should expect some doozies, but here's the kicker: The theme for February? Post-SCPocalypse.
 * SCP-764. Because puppets were not scary enough already. These will end up killing the user. How's that for a comedy routine?
 * SCP-800 is an antique scroll painting that regularly changes to reflect current political relations or tensions in East Asia. It currently depicts two soldiers in combat, mirroring the tenuous state of relations between the North and South Koreas. The Foundation once performed a test to see if adding objects into the painting had any kind of effect; an expert in East Asian art added a quiver of arrows to one of the soldiers. Three days later, North Korea did...something that ended up purged from the records and stopping all further testing on SCP-800. The arrow metaphor gave me a pretty good guess what happened...
 * It gives a date of May 25th, 20██. Now, scrolling through The Other Wiki, I found something that happened on May 25th.
 * Presumably, adding the arrows made the nuclear test occur. That's not the worst thing; there's mention that it once took the appearance of a Khmer stone carving. The description of said carving has been expunged. Predictable, considering what happened...
 * Almost all SCP [REDACTED] or [DATA EXPUNGED] marks are indicative of Nightmare Fuel or something else really gory. Most refer to something that the Foundation did, or something that an SCP did. Not the description of the Khmer carving–this was a non-fictional event carried out by real human beings. And the SCP Foundation expunged its data. Yeah...
 * SCP-823. A theme park that killed over 200 people in horrific ways (such as somebody in a mascot costume being filled with stuffing). Anybody sent in after that dies. So they can't find out what's going on, and that can't contain it because it's growing.
 * "Unable to determine context or content of above photograph."
 * The last paragraph in the "civilian deaths" section. Someone was completely dismembered... and, at the very end, it's mentioned that he was still alive when they found him like this.
 * The commander of the Mobile Task Force team was found dead from suicide. That's not the scary part. The cause of death was from "forced sexual entry through left eye"! Think about that for a second.
 * If you're savvy enough to realise some of the images are of a theme park that was supposed to open in Chernobyl, then it becomes...slightly less terrifying.
 * NO, NO IT DOES NOT.
 * SCP-741 is a sunken Russian submarine split into three pieces and guarded by the Foundation. The Nightmare Fuel? An attached interview with an American spy that said that the sub was carrying some kind of new weapon that not only made a bioweapons researcher sick, but that the Soviet couldn't safely control -- they sent the sub away to get rid of whatever it was.
 * Opportunity Knocks. Apparently based on a recurring nightmare of the author's...
 * During the experiments with SCP-914, they put in I Wanna Be the Guy. Setting on Rough made up the games used for IWBTG, simple enough. 1:1 made Kaizo Mario World. Fine gave them Super I Wanna Be The Guy, which is undoubtedly near-impossible. Finally, Super Fine had all information denied by the O5's. This means that this... thing that resulted from putting IWBTG in SCP-914 has been formally denied existence of by the Foundation's directors!
 * This story, especially the ending. Watch me fly!
 * The fact that you didn't list which SCP caused it is really freaking me out.
 * With all of the parts written, the final ending seems to be something more akin to a Crowning Moment of Heartwarming.
 * SCP-734. Awww, it's a cute baby boy. And if you touch him your body starts to break down and flake away.
 * SCP-058 resembles a bovine heart with tentacles and spikes. It also talks, although whether that's a good or bad thing depends on how creepy you find poetic ranting.
 * SCP-290 reads like a love letter to the Body Horror sub-genre: it reconfigures your body in wild ways while keeping you alive. The Experiment Log Addendum includes the poor test subject's head "slowly embedding itself into his thigh, both eyes absent", and a strong implication that -- horribleness warning -- the restructuring of his internal organs had re-routed some of his waste through his chest cavity.
 * While their treatment of D-Class personnel may be abhorrent, the way the organization treats certain SCPs (such as harmless ones, or non-hostile intelligent SCPs) indicates that many of the staff are more or less psychologically normal. Which means that normal people are engaged in the caretaking of these things, which may also include the horrible, horrible things they have to do to contain some of them.
 * SCP-775 are ticks as big as nickels.
 * " ." Thank you, SCP, because regular ticks weren't horrible enough.
 * SCP-370 is an memetic hazard that spreads via sight, knowledge about said hazard, sight of the end result, etc. Don't read it if you plan on getting sleep.
 * Not to mention that it's implied to be created by God.
 * Furthermore, people infected with it rewrite the page to spread it. How do you know you haven't been infected yet?
 * SCP-781 is a person who involuntarily manifests his own nightmares, and is killed by them an average of three times a week.
 * SCP-035, a comedy mask that constantly secretes a corrrosive substance from its eyes and mouth. This calls for a glass containment since glass dissolves slower than everything else. People that see it want to put it on and when they do they are possessed by it as their body slowly decays, even past the point where (mechanically) they shouldn't move. The entity has complete knowledge on human psychology and uses this along with charm and telepathy to convince anyone to do anything. It gets worse. After a while, they decided not to give it any more hosts, realizing the potential this thing had. It starting driving people around the cell to suicide and depression. They coated the walls with an alloy that blocks telepathic suggestions, and it started decaying the walls with corrosive blood. Now, its cell is almost impossible to enter, due to the dangerous phenomenon within. It gets worse. The entity also shows interest in 682, whose regenerative abilities could counter the mask's corrosive decay, giving it a permanent host.
 * SCP-343. He's God, how can he be scary? If he's God, that means he is (however indirectly) responsible for the SCPs. Possibly including SCP-682.
 * Now, now, in 343's defense, he/He denied having anything to do with 682, and in fact cannot see it. This gives a new level of terror. 682 vs. 343, and 682 would win.
 * 682 charged right through 343 without either of them noticing. Neither one can directly sense the other in any way.
 * It's pretty clear that 343 isn't "God", just an incredibly powerful being. Plus, God is not feeling like himself these days.
 * Either way, he can't touch 682 and is still more than capable of messing you up something fierce. 343's exact identity is left reasonably open-ended, so the reader can draw their own conclusion.
 * Although Your Mileage May Vary on whether God, specifically the Christian understanding of Him, is scary, considering the death toll he wreaks in the Bible...
 * SCP-966; an invisible humanoid thing that hunts by making you unable to sleep. Imagine it; you're in your house, at 2 AM and you are dead tired, but for some reason you just can't sleep. The night goes on and on, you keep moving uncomfortably in the bed, and nothing. Comes 6 AM and you have to get up to go to work. The whole day you are just shambling through the world like a zombie, trying desperately to at least have a little nap, but you simply can't get asleep. When you're finally so tired you can't even move, a sharp pain comes from somewhere on your body and all you see is your flesh being ripped off with no clear reason as to why.
 * YOU SHOULD HAVE WARNED US ABOUT THE PICTURE. JESUS CHRIST.
 * More squick than terrifying, but when someone took a picture of one of those creatures with SCP-978 (the Desire Camera), it showed a picture of two of them mating. Just... try to imagine those things doing that... *shudder*
 * They also seem to bear more than a passing resemblance to the Silence from Doctor Who.
 * Four words: I am a toaster. God, reading my page is still scaring me.
 * To elaborate, I am a toaster that makes people refer to me in the first person. Nobody's ever been able to refer to me in the third person, no matter what they do or don't know about me. Eventually, they completely forget who they are, and usually die when trying to emulate the functions of a toaster (one person died because she ingested so much bread that her stomach bursted). This short story also demonstrates my potential for creepy.
 * SCP-455. A ghost ship.
 * It's more like an Eldritch Abomination ship. For example: Weird temporal distortions, messed up interior dimensions, not really having any clue what goes in inside, things getting worse for exploration teams, and so on and so forth.
 * Thank you. I was having trouble putting into words exactly how messed up this thing is.
 * Dr. Bright. Aside what he did to his own brother, he is a god of Fridge Horror. Just look at this list. Sure, it's damn funny, but then you realize, that he is one of most important people in charge of all this gallery of horrors and is an irresponsible sociopath. It's like a monkey being in control of nuclear arsenal.
 * Word Of God says that the list is not in-universe. So, although Bright is an asshole, he's not an completely irresponsible asshole.
 * But then again, half the time he is a monkey, so it kinda makes sense.
 * Bright's own life is a Fridge Horror in and of itself.
 * SCP-363, the centipedes that grow enormously in the dark. And not into giant centipedes, but into horrific tentacled monsters. To top it all off,
 * Y'think that's bad?
 * SCP-632, a species of tiny, hermaphroditic, self-fertilizing spiders. Their eggs are light enough to float on almost non-existent breezes. When they land on warm skin, they hatch, burrow into your sweat glands and travel through your blood vessels to your brain. Then they burrow in THERE so they can feast. This causes a minor headache, which is alleviated by light tapping on the closest part of their head. As they continue, the headache gets worse, meaning the host has to hit their head harder. Eventually this leads to caving your own skull in.
 * SCP 700. There was a hole here. It's gone. Now the hole's back, but the person who fell in is gone.
 * SCP-096 is a creature who is docile until you look at it's face at which point it will charge at you and kill you. The bad part about this is this works even with pictures and it will track you down no matter how far away you are. Also there have been pictures spread on the internet and the SCP Foundation is still in the process of removing them.
 * To understand how horrific this is read Incident-096-1-a in which SCP-096 tracks down someone who saw it's face in a picture in which its body was only 7 pixels. So you can be looking at a picture and never notice it's there.
 * Oh, and did we mention that when enraged, it's invincible? And that it's capable of bringing down an AWACS plane? And that it doesn't just kill its victims, it also [DATA EXPUNGED] them, leaving no trace of the body?
 * There is one bit of good news:  Though it took   to convince the 05 to act.
 * You know you're dealing with some master writers when they can make cups Paranoia Fuel. SCP-198, a cup that can teleport and pretend to be other beverage containers. When you pick it up, it instantly bonds with your skin and cannot be removed, even by amputation. You rapidly become dehydrated unless you drink from the cup. What's in the cup? Human body fluids, like spit, sweat, bile, mucus, and...some less pleasant ones. Also, since you dehydrate so fast, your only hope is to chug everything in the cup constantly. I'd make a 2girls1cup joke here, but I doubt it would help.
 * SCP-182: A nice, cheerful guy who wants to be friends. Oh, and did we mention that he's deaf, mute, and horribly scarred, and he compensates for the first three by involuntarily riding shotgun on your senses when you get within ten meters, and if you stay around him there's a 97% chance you'll go insane? And he knows this. And he can't do a thing about it.
 * Well, how bout the Tooth Fairies?
 * SCP-084. The static tower. It causes distortions of reality within its area of effect, trapping a small town within. They can't die, age, and have no need to sleep or eat. They also can't escape. One man was picked up four hundred meters from the city limits. He'd been traveling for six years.
 * SCP-616 is a prototype airplane. The emergency door opens on its own every 30 days, revealing what is essentially implied to be Hell. However, the worst thing you can do is let the door close before the manifestation is over...
 * As scary as that entry is now, it was actually a lot worse when it was first written. See for yourself. Among other things, it tells you exactly what was on the recording.
 * SCP-456 are bedbugs. When they bite you, they produce narcotics in your brain, causing you to feel increasingly sleepy until you sleep constantly, causing you to die of malnutrition. They can't be distinguished from ordinary bedbugs, and you probably won't know they're 456 bedbugs until it's too late.
 * Even worse, they exposed four D-class to the bedbugs. After expending three of them, they put the fourth one on a regimen of IV nutrients, blood transfusions, and narcotics antagonists. He's been asleep for a long time. The number of days is blanked out, but it's a triple digit number...
 * SCP-686 By itself, it's not scary, but once you think about the implications, you will freak out. 686 is just milk, except it contains an infection that causes mammary glands to develop in mammals, even males. If milked regularly, the disease won't advance any further. If left unchecked, however, your entire torso will become an gigantic udder. Not only that, but because you have to eat all the time to keep your metabolism up, you'll become nothing more than a docile animal. Just imagine what a sick mind could do with that. On the other hand, you could consider it Fetish Fuel.
 * SCP-860 seems fairly ordinary by SCP standards - a blue key that leads to a blue-misted forest with some unseen creature stalking you as you walk through it. The real chiller is the end of the last exploration log and that very last bit of audio.
 * SCP-624 seems on the surface to be one of the more benign SCPs. It is an ordinary MP 3 player which, if used, plays the users favorite music, covered by a more musically talented version of the user. But if someone with no musical preferences uses it, it plays the users soul. Meaning that you hear everything you have ever felt and heard and thought, including the bits you are ashamed of, right up to and including your own death.
 * Death nothing. The examples provided in the main SCP page for 624 state the last track continues into the afterlife. Specifically, continuing as the soul is tortured in hell. This happens Twice.
 * SCP-750 is a pair of contact lenses made by The Factory. When you put them on, it displays a variety of changes, like food becoming piles of limbs and gore, walls becoming coated in biofilm, and the skies becoming red and black. Victims who have the glasses on for too long usually get schizophrenia or PTSD. Real scary part? The lenses LET YOU SEE THINGS AS THEY REALLY ARE.
 * Goddamn it, the whole website. The titles are very mundane numbers and stuff, so...you never know if you're clicking on something funny, squicky, or an insane Eldritch Abomination that will keep you awake for days. And the pictures...oh, god, the pictures...
 * According to The document recovered from the Marianas Trench, they frequently have containment failures so massive that it kills nearly every person on earth, and the survivors use SCP technology to repair the devastated planet, clone the dead and make them think nothing happened, with geologic features covering up bigger damage (evidently the Marianas trench used to be a dry land ravine). You'll never know how many times you've died to make it to the end of the "week", or how many years have passed between Monday and Friday....
 * How about SCP-528? They're little plastic containers containing silly putty that copies whatever image of a person is pressed onto it. Sounds harmless right? Wrong. Whatever happens to the picture happens to the person. The tests are horrific, the first one involving a D class having first his arm stretched unnaturally long, which is apparently painful and then torn off. The second subject is crushed into a ball and suffocates on his own flesh. The third one however is the worst of all. The putty is dipped in boiling water and the D class actually melts until he suffocates on his own nose.
 * SCP-736. It's Tiberium, except that it feeds on your blood.
 * SCP 939. Read the whole page and all its included documents.
 * The worst part? Putting them into 914 on "Fine" and "Very Fine" killed them–in essence, they're supposed to be dead.
 * On the page "Log of Anomalous Objects", there's a mention of a piece of charcoal that writes (regardless of what the writer is using it for) "Please help me! I'm trapped in the charcoal!" every few seconds. And the foundation found it too boring, and put it into storage. Maybe it's just me, but I find that terrifying.
 * SCP-772. More Body Horror, except this time with bugs the size of your thighs.
 * Elaboration: They're wasps, Made of Iron to an extent where bullets and even fire are useless, with a stinger longer than they are. When they sting you, they inject eggs under your skin, which is described as being 'excruciatingly painful'. Read the whole thing, if you can stomach it.
 * It's also implied that they're more likely to go after you the more afraid of them you are.
 * SCP-592. It's a history textbook. From an alternate timeline. If you read it, you're absolutely fine, as long as you read about something that happened before June 15th, 1956, when the timelines diverged. Anything past that and your mind is warped -- you start remembering things according to the alternate timeline's history, not reality. Reading an entry covering within 2 months from June 15th, you get a headache and can recover. 2 years, you'll have panic attacks and minor mental illness for the rest of your life. 10 years, psychosis and dementia. Anything past that and your perception of reality starts to break down completely.
 * It gets worse. People who start remembering history differently due to this book can be physically modified to match the book's history -- gaining scars and losing limbs in wars that never happened, for example. Worse still, a significant number of the articles mention known SCP objects, suggesting the divergence point is  (The timeframe is actually spot on for this theory.)
 * The Foundation is using a complex system of computers to analyze the book, due to nearly anyone even looking inside the book going absolutely stark raving mad. They are effectively getting the computers to "learn" that history and tell us it in the most vague terms possible. One of the final entries on the page suggests something far, far more sinister is at work:
 * The Foundation is using a complex system of computers to analyze the book, due to nearly anyone even looking inside the book going absolutely stark raving mad.

One of the final entries on the page suggests something far, far more sinister is at work:

"Director Jones: You think Bigfoot is funny because we want you to think Bigfoot is funny."
 * SCP-930. It's an uncharted island. The birds around it, 930-1 attack anyone who gets close. They don't kill, just cause minor wounds. They're not trying to hurt you, they're trying to get you away from the island. There's something much worse there...
 * SCP-716. On the surface, it doesn't seem too scary- just some kind of ghost train, but that's until you get to the part about a boxcar filled with dead horses, or a tanker filled with human bile. Plus there's the fact that if it comes near you you're compelled to kill yourself. And if you're on board the train when it gets too fast, it's likely that you're sent to another planet to die.
 * SCP-870. Ever drop something and can't find it again?
 * SCP-1000. My god. It's Bigfoot.
 * Bigfoot used to be the dominant species on the planet. Humans were hunted to near-extinction, put in zoos, etc. Meanwhile, Bigfoot created things even humanity can't comprehend. Organic technology, mostly. Eventually, humanity acquired Bigfoot's technology and used it against them, wiping them from the planet, destroying their minds, their technology, everything. Then, humanity wiped its own minds, forgetting everything they had done and rising to become the dominant species. However, recently, Bigfoot has been regaining its mental capacities...


 * And later on, they leave us this message:

""I wake/I see all/And find it lacking""
 * SCP-517 I became paranoid after having seen one of the pictures move (having been a .gif), so I have a tendency to quickly copy and paste the link to a picture to check if it'll spaz out in any way. The picture with the glass is a .gif, so I didn't stick around long enough to see if it would move.
 * Why are all old photos in black and white? Not because we didn't invent color photography until relatively recently. Because we didn't invent COLOR until recently.
 * Although that could become Nightmare Retardant when you remember that that was the premise of one of Calvin's father's Little-Known Facts.
 * SCP-993. It's like Candle Cove as done by a Monster Clown - except Candle Cove didn't brainwash children. In one episode the clown just stares at you. For the entire episode. What makes it worse is at in that next episode you can tell who he's really staring at:
 * It already knows about certain SCP's, and how to breach containment for them. For all we know, it may have already found one
 * One short story on the site makes Bobble even scarier with The Reveal that In the same story, Bobble also reveals that
 * The living toothpicks...
 * To elaborate: They are a species of botflies. Botflies are insects that nest in human flesh, with their larva feeding off the person and eventually burrowing out. These particular flies can impersonate toothpicks, and lay their eggs in the gums, eating their way out. And there's a picture.
 * SCP-1100. It's a substance that mutates life. How is that any different from similar items? Well, it started by only mutating plants into forms that were hostile to humans and/or poisonous. Then it adapted to mutate animals as well. When presented with a choice of attacking a prey animal or a human, the human is always targeted. It can affect plants, wild animals livestock and even pets.
 * The SCPs that specifically target children really creep me out. Baba Yaga, the living pinata that turns children into candy that turns children into more murderous pinatas, the children's mittens that rot flesh when worn, the kiddie pool that can teleport people to space, Bobble the Clown, the treehouse, the child-controlling bone flute that makes its wielder abusive towards children...
 * SCP-136 is a doll. When you look at it for too long, you get mind raped (in a way heavily reminiscent of physical rape) by a naked, insane, blood-covered ghost thing that inexorably floats towards you, laughing, before shoving its face right ups to yours and screaming before disappearing. It usually takes the form of a woman with an obscenely large mouth and oversized breasts. And now we're finding out that it can kill people...
 * Dr. Wondertainment, and the fact that his/their SCPs are made for children.
 * SCP-953 is pretty freaking scary. The interview with one of the Foundation agents who encountered it is... yeesh.
 * SCP-089 is a golden idol with a cavity in its chest that either causes or can prevent horrifying disasters; either way, they will only abate if Protocol M8 is fulfilled. What is Protocol M8? The statue names two people: SCP-089-A and 089-B. The foundation will send out a taskforce to convince 089-B to complete Protocol M8 out of her own free volition. Then comes the Wham! Line.
 * Worse still, they haven't yet found someone to carry out Protocol M8 for the most recent prophecy, which is naturally hidden behind a "DATA EXPUNGED." In the past, when it took 49 days to find someone willing to carry out the protocol the casualties were in the thousands. (It's implied they could have been much worse.) By the date shown on the page it could be up to nearly 12 years since the most recent prophecy.
 * SCP-1042 is a stone brick that has the strange property, when exposed to an electric current, to record and broadcast events happening near it, like a spectral videorecorder. But that's not what makes it creepy, nooooo...
 * And for Nightmare Fuel it is really hard to beat...the Ethics Committee. There is no canon, and even if there were the Ethics Committee would never acknowledge this document, but the thought that someone is evaluating the moral cost of everything the SCP does, and they are still doing so much of what they do... that can keep you up at night.
 * It's like a reminder that yes, horrible things are done. Yes, the SCP is doing a lot of evil with their actions. But would you prefer the alternative? SCP stands for Secure, Contain, and PROTECT. They are here to protect the general public, even if it doesn't seem that way all the time.
 * And the And Then I Died Contests were games, but they involve stories of deaths involving the SCPs in some way, and you get to guess which was involved. And most of the stories take place before the SCP in question came under the Foundation's control. They not only remind you of what these things can do to ordinary human beings, there's the added scariness that, however horrible the Foundation may be, it would be SO MUCH WORSE without them.
 * SCP-435 is a meteorite to which a very strange entity that is seemingly immaterial, yet does horrible things to solids that it touches, is bound. Also, if the meteorite isn't illuminated at all times, it can move around. We aren't told what happens when it intersects with landmasses or water, but apparently when it happened during its retrieval it had to be passed off as a nuclear test misfiring. Apparently
 * SCP-710. Entering this city will cause you to slowly fade from existence. And it's totally irreversible once the symptoms manifest, to boot!
 * SCP-515 is a young man who causes celestial objects to move towards earth whenever he moves any part of his body. The good part is that he is asleep and is easily constrained, the bad part is that he sleepwalks and his very breathing counts as movement. The sheer impact SCP-515 has on this troper is that not only is it causing a potentially world-ending scenario, it isn't even trying to do so. In addition the feeling of inevitability really nags away on you.
 * SCP-895 is not really all that scary to read about. A little chilling, but the really scary thing
 * SCP-1237 is a brain wave that occurs in some people, causing them to go into a deeper-than-REM-sleep state. It causes the person to experience dreams that are not really any different from other dreams. The kicker, though, is that whatever occurs in the dream becomes reality. That's right, it's literally a reality warping dream. Some examples of effects from 1237-sleep include people changing gender, significant changes to city layouts, people losing or regrowing limbs, people gaining super powers, and governments being changed. The scary part is anyone involved in the dream will simply see the changes as normal, but will still have memories from before the change (imagine remembering two different things and believing that both are true, even when you know they simply can't be). However, the memories of people not involved in the dream will be unaffected, meaning they could get up one morning and be in a city they don't recognize with a new government regime they know nothing about. And absolutely none of it is under the dreamer's control. And since this is a brainwave we're talking about, the Foundation can't contain so much as limit it's influence and mind-wipe everyone affected with class omega amnesiacs. And the dreamers themselves? They're taken by the Foundation and constantly mind-wiped to stop them from forming memories and never allowed to enter REM sleep again.
 * SCP-017 is a shadowy figure roughly the size of a young child. Unlike some other dangerous SCP objects, it generally remains stationary and does nothing to actively harm anyone... until a shadow is cast upon it. When that happens, it will immediately leap at and engulf the object or person, then return to normal size as if they were never there to begin with. And all of the Foundation's attempts to discover what, if anything is within those shadows or where the victims go has been unsuccessful.
 * SCP-020 is a germaphobe's nightmare-- a mold that is invisible to humans unless videotaped or photographed, can grow all over your house and even on your body, and changes your personality to make you more sociable so it can spread to all your friends.
 * SCP-1548. 'The Hateful Star.' It's sentient, intends to destroy us all, knows we know about it and is coming closer. And worst of all, there is nothing whatsoever the Foundation can do about it.


 * SCP-973 is essentially an evil police man who likes to chase down unlucky vehicles at high speeds with his police cruiser until overtaking them in a few minutes. Yeah sure, this SCP may not SEEM as horrifying as the other SCPs listed above, but consider that it has already killed 34 people from 19 vehicles on the highway where it has been driving, with said victims eviscerated, raped, and damaged beyond the point of identification and their cars sustaining heavy impact. Also, attempts to destroy the highways used by SCP-973 have proven ineffective, as it can simply relocate to a different road and attempts to contain it led to the death of nine agents. And as a final little note to keep you awake at night, a post-mission interview by one of the surviving agents revealed changes in the police man's appearance, with red eyes and a black hole where his mouth should be. No teeth, no tongue, just a hole.
 * SCP-1983 is a farmhouse that has a set of containment procedures pre-written by an unfortunate Agent who became trapped in it. The classification reads "Keter, God help you", and the Special Containment Procedures read "You're going to die, you poor dumb fuck." It Gets Worse.
 * SCP-833 will make you WISH you were only infected by ordinary intestinal parasites. Anyone infected by this SCP become kinder and more generous. Doesn't sound bad? WAIT there's more! Not only do the victims become more altruistic, they try to help others in the best way they can think of....by feeding them pieces of their own flesh which they think is the most delicious thing in the world. Due to most people's issues with cannibalism, the infected try their best to keep their actions a secret.
 * SCP-1076: Say your a little kid whose parents discovers a 3-5 year old child who looks like they suffered from severe abuse. As responsible and sympathetic human beings, it's only natural they take him/her back and care for them until they get better. But then, after a while they begin to show a little TOO much concern for this child, to the point they begin to forget looking after YOUR needs. Eventually they stop paying attention to you and you begin to suffer from starvation and neglect. You become lonely, withdrawn, and depressed, desperately in need of the love that has become monopolized by the strange new child. Eventually your condition attracts the attention of concerned school authorities and social well-fare agents. As they investigate the cause for your misfortune, your heart lights with hope that they will help save you and your parents from this nightmare. But no, it was all just a Hope Spot, since now the SCP the authorities have encountered have ensnared their affections just like your parents. And now, with no other hope left, you watch as all your family and caretakers succumb to starvation, disease, or fights to the death as they neglect their own well-being as well as yours attempting to care for their new "baby".
 * At first glance SCP-428 just looks like an ordinary huddled crowd of people. In reality, it is actually a Hive Mind whose internal organs have been removed and replaced with an unidentified amorphous mass attached by umbilical-like lengths of flesh. Any person who comes within two meters prompts the crowd to go into hostile mode by grabbing the unfortunate victim and pulling them into their mass, where they are assimilated into the crowd within ten seconds (those who try to escape are hunted down by the crowd who use the methods gained from each members' knowledge, skills, and memories to absorb anyone who gets in their way). Remember, the members could be your friends or family, which the SCP may use to their psychological advantage to lure you into their fold.
 * SCP-511 exemplifies Cats Are Mean Up to Eleven. It's an SCP made up of hundreds of feral neglected diseased cats and some kind of cat-like.....THING that takes the form of a mass of extra limbs, eyes, mouths and other organs made up from the bodies of said cats as well as other material (small rodents, plant material, insects and insect larva, black mold, human [DATA EXPUNGED]). It's also in a constant state of degradation and decay, which means the cats find new material to add to the mass. And that's not all. An interview with a survivor of a mobile task force sent for containment of the SCP revealed that when they tried to roll the captured cat thing SCP out the door, it exploded and splattered its contents onto the force, who were immediately torn about by the horde of rampaging cats. May I remind you that the surviving member had half his face ripped off when he accidentally locked himself in his van with just one of the cats trying to escape the onslaught of feline fury. And it's revealed it's not the cat thing that influencing the cats' actions, the cats MADE it because they hate humans.
 * SCP-1055. It appears to be a harmless little teddy bear, but it can change in size and shape into an enormous Eldritch Abomination based on how many people know about it. Worse, its behavior is also influenced by how people aware of it generally think of it; hostile and fearful awareness make it act in a more hostile and fearful manner. It has no upper limit to the size it can achieve, so even what starts as benign awareness can quickly grow fearful. The SCP is believed to be capable of causing an XK-class end-of-the-world scenario, and the only way they have to contain it is to have a mentally retarded man constantly hug it. The only way anyone thinks they can destroy it would be to kill at least 80% of all people who are vaguely aware of the existence of the SCP...which now includes you for having read the page for it. And this entry.
 * Speaking of scary teddy bears, SCP-1048 is a vicious subversion/deconstruction of "Team Pet"-style SCPs that aren't kept under close watch because they're considered harmless. It provides some excellent perspective on why the Foundation continues to use the methods that they use when handling SCPs classified as "Safe."
 * SCP-1981. Holy. Crap. Just try watching any political speech after reading that.
 * The background "music" from the SCP-087-B game. This has to be the most spine-chilling, paranoia-inducing track in video game history.
 * SCP-1344-J otherwise known as, doesn't seem frightening when you know what it is, but if you read its description before you know its name, you may never look at it the same way again.
 * SCP-1875 is a chess computer that comes with an engine with a timer that has it's maximum setting worn out, a 32-piece chess set made out of human bone (sorta creepy), and a suit of samurai armor presumed to be used for performances involving the computer.
 * Special memntion goes out to
 * SCP-956, quite a disturbing inversion of pinatas.
