Daydream Believer

"Frylock: Shake! Highlander was just a movie. Master Shake: No, Frylock, Highlander was a documentary, and the events happened in Real Time."

- Aqua Teen Hunger Force

Particle physicists have written much on the possibilities of multiple universes. Every single subatomic possibility spawns its own unique universe, each of which in turn spawns new universes from each of its own subatomic possibilities, creating the vast web of The Multiverse. And so, the reasoning goes, somewhere out there in that vast sea, why couldn't there lie universes wherein the events of our favorite TV shows, video games, and other media properties actually happened?

The Daydream Believers are a subgroup found in several fandoms who believe that the events, characters and places depicted in the object of fandom are, in some form or another, real. This is often Handwaved by taking alternate universes into account. After all, if there are infinite universes out there, at least one of them must resemble the one from the TV show/movie/book/video game, right?

Trapped in TV Land, Refugee From TV Land, and Welcome to The Real World all play upon this variant of the trope.

The most common versions of this sort of fandom, of course, (and immensely more popular than the hard-core versions) are those which take this sort of hypothesis as speculation, albeit with a grain of salt. For non-believers, these could be considered Recursive Canon.

Certain types of fiction tend to attract the "casual" (socially accepted) Daydream Believer:


 * Mythology including parables, Fairy Tales, and works that assert All Myths Are True. As anyone who has spoken to a fan of The Iliad knows, these works tend to attract a fandom who approaches the work from a deep-seated Jungian perspective—a desire to believe the works are true on some level. Works that assert all myths have a "grain of truth" encourage this.


 * Literary Agent Hypothesis: Works that assume a story is true and has been passed down to the Real Life author and fictionalized often attract a fandom which insists on Willing Suspension of Disbelief. Alternately, fans unfamiliar with the background of the work will insist on believing that the hypothesis is true after spending many years assuming it without being told otherwise; see Based on a Great Big Lie.


 * The Multiverse is the latest, most popular form of Recursive Reality these days. Works that postulate a multiverse naturally get the mind to thinking about the possibilities—sure, The Last Unicorn might not exist, but is it really so far fetched to imagine some sort of unicorn exists on infinite Earths? Moreover, there is a version known as Transfictionality which asserts that the author himself is God of these imagined alternate universes. This bridges the gap between Literary Agent Hypothesis and All Myths Are True.


 * Speculative Fiction, specifically hard Science Fiction appeals strongly to people who sincerely believe that Life Imitates Art as Science Marches On, and point to numerous instances of Defictionalization inspired by existing science fiction prophets. The characterization of the people inhabiting the future story is less important than the fact that the technological setting that interests them JUST! MIGHT! EXIST! See I Want My Jetpack. Moreover, a version of Transhumanism, called The Singularity asserts that humans will eventually Ascend to a Higher Plane of Existence.


 * Works that postulate the existence of a Masquerade, Mouse World or Magical Land hidden from day-to-day life tend to appeal to those who are Longing for Fictionland, but such works generally follow a template that expressly divorces the setting from the world of reality; compare This Is Reality.

Works that attract daydream believers tend to mass-produce meta Wild Mass Guessing. Persons who intellectually know that something isn't real, but insist it would be better if it were real, have their own separate trope, Longing for Fictionland. The less-extreme version of this is Mythopoeia, where the author is satisfied with achieving versimilitude, by building a fully fleshed-out world on paper.

Note that all this does not include speculative non-fiction or historical works, published with respect to things that the author believes or predicts, such as philosophy, religion, Historical Fiction or works that purport to reenact events as they "might have really occurred" on which the myths are based. Such works do not count as Daydream Believing, however, the reader may insist it can only have happened exactly that way as depicted in the work. Also, pulp fantasy and soft sci-fi, which do not postulate their own existence and are meant to be enjoyed as brain candy, are not typically attractive to the "casual" Daydream Believer. However, such works may still be subject to arguments over what Absolutely Happened.

'''Some people take it much, much further, however. These are the "hardcore" Daydream Believers:'''


 * A few believe that the story happened in this world, but some events (or The Man) have conspired to keep this fact a secret, and that the fictional works were created so that people would think "You've been watching too many movies!" if they were told about what really happened.
 * For the most extreme example of this, look no further than The Book Which Is Not Written (Assuming you can find a copy.)
 * Urban legends and chain-letters about how some author or popular story was inspired by a real incident fall into this.


 * "Soulbonders" are people who feel they have some sort of emotional, spiritual, or mental connection with fictional characters. This ranges from rational people who realize that their "soulbond" is a mental imprint of the character and not the character itself (and therefore technically don't fit this trope) to those who believe they've actually married a character on the astral plane.


 * "Otakin" or "Otakukin" believe that they are the specific characters, but in an alternate universe or another life or something. Related are "Otherkin", who believe that they are reincarnations of unspecific members of fictional races or species, and Therianthropy, which is like Otherkin but only with real animals.
 * Among the ways these groups express their connection: "I feel a connection to X," "I may have been an X in a past life," "I have the soul of an X," or even "I can physically shapeshift, but don't because they'd cut me up!" or other possibilities. Basically... you really should ask the individual.
 * This could overlap with religious beliefs in reincarnation, if not taken to extreme.


 * "Plurals" is a label used by people who have, or think they have, multiple personalities or persons sharing the same body (multiples). Psychologists generally believe that the persons are fragments of the whole personality that have been forcibly fragmented due to extreme trauma and that they should be "cured" by integrating the persons. "Multiple systems," on the other hand, often find that they function better if the different persons learn to cooperate with one another; in fact, many of them find it impossible to integrate successfully. In some cases, the personalities who co-inhabit their bodies are characters from works of fiction. (See "soulbond," above.) Most plural systems aren't Daydream Believers; however, there are the few who believe they are possessed by actual vampires, demons, or aliens.

As strange as it seems (remember that this is the Internet) and as hard as we try, we are not making any of this up. For the nonbelievers, the fun begins when one group argues their belief is more realistic than the others.

The trope takes its name from a song by The Monkees, but has nothing to do with the song. Compare Epileptic Trees, I Just Want to Be Special, Longing for Fictionland, Special Snowflake Syndrome.

See Defictionalization for a justification.

Recursive Canon is when works allege themselves to be actually happening in the world of the story, which usually takes the form of one of the examples mentioned up top (Literary Agent Hypothesis, The Multiverse, Transfictionality, etc.) For more on such Mind Screw scenarios, see Recursive Reality, where a work postulates the existence of one world hidden within another.

Ascended Fanboy and I Wish It Was Real are the fictional version of this trope.

'Note:'' When adding new examples to this page, keep the Rule of Cautious Editing Judgment firmly in mind. Include only examples of people who, in the reductionist way, believe in works written and published with the full intent of being seen as fiction. Try not to snark, either. We're not here to call names on the playground, after all. And please do not confuse this trope with Clap Your Hands If You Believe.'''

General

 * Dragons in general. (Except for Komodo Dragons.)
 * Zombie fandom. The number of people who have taken the Zombie Apocalypse seriously, forming plans to survive the onslaught, can either be really funny or really scary. Online debates as to the best weapons and places to bug out in can be Serious Business in some circles. Fortunately, this is subverted by the fact that the vast majority of them are in on the joke. Hopefully.
 * Most are bored and/or disaffected students with too much time on our hands. Most of the rest are survivalists who believe that, if you're prepared for a hypothetical zombie apocalypse, you're prepared for any possible catastrophe (the reasoning behind the Zombie Squad). Of course, there's also a small minority of psycho gun-nuts who just want to shoot things.
 * While a tiny minority, there are some members of the Furry Fandom who honestly, truly believe that there are such things as werewolves and other were-creatures, and that scientists are on the verge of creating a true human/animal hybrid. A few obsessed fans even go so far as to insist that their fursona is themselves, all flesh and blood, and only those "in tune" with their animal nature can see them as they're truly are instead of as a human.
 * It is of note that most members of the therianthrope and otherkin subcultures do not believe they are physically their creature-selves, only spiritually/mentally.
 * It might also be important to note that the Furry subculture is not, in and of itself, related to theriantropy, otherkin or any other belief systems for that matter, any more than the Goth subculture is related to people who drink blood and call themselves vampires. Although, due to the demographic overlap, this troper finds it difficult to believe there is no connection.
 * However, there is overlap: after all, if you believe you were an animal in a past life, or have the soul of one, or "should" have been one, or have some other spiritual connection (remember - with all of these terms, there are a wide variety in what individuals who go by the name are talking about) then dressing up as said animal may be the next best thing.
 * Interpretations of Carl Jung's writings on the collective unconscious and archetypes in storytelling could be seen as an Older Than They Think invocation of this trope. In brief: the idea is the human brain is wired to believe in certain myths and stories, hence the almost-universal mention of a 'great flood' in nearly every recorded creation myth (which has been interpreted as everything from life ascending to land from the primordial oceans, to the melt after the Ice Age, to an unconscious memory of being suspended in fluid in utero). In other words, a favorite fictional character or one that you identify with in particular is evidence that your brain works similarly to the author's, and that archetype 'speaks' to you in the same way as it did to the author/creator. Not an exact summary, but one of the general ideas.
 * From The Other Wiki: Tulpa. The idea that a "fictional" character can be brought or "willed" into existence, or at least as a symbol in the sense of an archetype existing within the collective unconscious (see the many references to Jung in this article). Of course anyone using this argument to insist that Sephiroth or Lestat is real Did Not Do the Research.
 * This turned out to be popular enough to have a creepypasta made about it that may actually explain it in a way most people would understand.

Anime & Manga

 * A few Dragon Ball and Naruto fans believe that Ki Attacks, as in explosive light-show powers, are a real martial art that humans can learn. But only when nobody's watching. And they can argue and explain why the other fandom's powers are unrealistic.
 * A caveat: many real-life martial arts do involve processes which are explained in terms of ki manipulation, but mostly as a metaphor for something more complicated and materialistic. Beam Spam is not involved.
 * A lot of what gets described as "ki manipulation" is simply the result of the human species being stronger/faster/more durable than most people think or believe.
 * The Japanese 2-D Love Movement. 'I’m not saying that everyone should throw away hopes of real romance right away. I am simply saying that guys like me who have gotten to a point of no return can be happy living in 2-D. - unofficial founder/guru (actually he wrote the first book recognizing the phenomenon and started advocating for it), Tohru Honda.
 * In related news: Japanese launch campaign to marry comic book characters. When "____ is mai waifu" goes out of hand.
 * Truth in Television: An example of this happening in real life. Wow. Just... wow...
 * And it's not just limited to Japan either. Meet the Korean Otaku who married his Fate Testarossa-Harlaown Body Pillow.
 * In-universe, Ruri "Kuroneko" Gotou of Ore no Imouto ga Konna ni Kawaii Wake ga Nai appears to partake of no small amount of this behavior, claiming to have supernatural powers and threatening to curse those who annoy her (in a world with no observable magic or other paranormal phenomena).

Comics

 * What about the fans who believe mutants really exist?
 * OK, they do—and with a broad enough definition all life is mutant—but they mean the kind with laser eyes and psychic powers and blah. To give an example of real life mutants: Anyone with red hair is a mutant. It's a mutation that causes pigmentation of blond hair, turning it red. That's how awesome and interesting mutants are(n't)!
 * There is a woman who believes that she's married to X-Men's Cyclops, and claimed she told her children that he's their real father. Poor kids.
 * Alan Moore claims to have met John Constantine in a bar.
 * Since Alan Moore wrote Hellblazer, this is more an example of the author believing his creation is actually real in some way or another. Possibly he based the character on someone he met in a bar.
 * Actually, according to Moore himself, this was after he'd created the character.
 * Moore also claims to have conversed with Mercury. The God from Greek/Roman mythology.
 * Yes, but he's also claimed to have gotten his talent by beating the devil up for his lunch money. It's probably safe to say that he's just like that.
 * In-universe example: Booster Gold, time-traveling hero, once tried to persuade his boss Rip Hunter to let him make a stop in the 1950's. His apparent motivation? To meet Fonzie. When Rip informs him that The Fonz is a fictional character, Booster replies, "now that's just mean". Knowing Booster, it's hard to say if he was joking or not.
 * Peanuts has Linus and his unwavering belief in the Great Pumpkin.
 * Jason of FoxTrot falls into this on occasion. At least once, he commented that Star Wars really did happen and the production reports were just "monkeys on keyboards" and had to be told that comics didn't reflect reality when his Spider-Man web-shooter didn't work.
 * There are quite a few people out there who've managed to convince themselves that Death is a cute, perky Goth chick.
 * Considering the alternatives, who wouldn't want to?

Fan Fiction

 * In Kyon: Big Damn Hero, Kyon's sister ardently believes that Magical Girls exist and that she will become one if her mother lets her go on a field trip to a shrine. Notably, in this case it is meant to be cute, not scary.

Films -- Live Action

 * There apparently is a body of believers out there that thinks we are inside The Matrix right now and need to wake up.
 * The release of Inception doesn't help either. See what happens when you play "Je ne regrette rien" when they can't figure out where it's coming from.
 * Fictional example: In Kiss Kiss Bang Bang, Harmony told her sister (who their father sexually abused) that she was actually adopted and her real father was a Hollywood actor who was in town shooting a movie. She is distressed to realize years later that her sister believed her and kept to that belief for her whole life.
 * The entire plot of Galaxy Quest rests upon Daydream Believer scenarios. First there's the aliens who come to Earth, who believe the Galaxy Quest television show is actually a historical document. So deep is their faith in the daydream that they have gone to the trouble of building exact and functional representations of the technology on the show, and, upon meeting them in real life, don't realize that the actors aren't really their respective characters. Later, said actors are rescued by an obsessive fanboy who believes the show is literally true.
 * In the fanboy's defense, his favorite actor told him it was all real (it was easier than explaining the whole thing). Presumably, after everything was over they filled him in a little bit more accurately.
 * Candyman. Candyman. Candyman.
 * Some conspiracy theorists believe that every movie about space aliens ever made is really the government trying to disclose the existence of extraterrestrials without freaking people out.
 * In a dark version of this, in Ghostbusters, the four heroes are trapped by Gozer and challenged to choose the form that Zuul will take when he arrives. Naturally they try to clear their minds to prevent that form being something horrible, but then Ray thinks of the Stay-Puft Marshmallow Man...
 * Jamie from the Disney Channel movie Read It and Weep soulbonds her own fictional alter-ego IS. IS also fronts on occasion making Jamie an example of a soulbonder who is also plural. However,.

Literature
""His fancy grew full of what he used to read about in his books, enchantments, quarrels, battles, challenges, wounds, wooings, loves, agonies, and all sorts of impossible nonsense; and it so possessed his mind that the whole fabric of invention and fancy he read of was true, that to him no history in the world had more reality in it. ""
 * Older Than Steam: A fictional example of a Daydream Believer is Alonso Quixano, a retired hidalgo who becomes convinced that the books of fictional chivalry he's obsessed with are really histories which depict the world as it actually is. His friends fear he's gone mad, but he cobbles together a suit of armour, renames himself Don Quixote, and rides off to tilt at windmills.
 * The narrator describes Don Quixote at Chapter I, Part I:

""Those two ladies were very unfortunate not to have been born in this age, and I unfortunate above all men not to have been born in theirs. Had I fallen in with those gentlemen, Troy would not have been burned or Carthage destroyed, for it would have been only for me to slay Paris, and all these misfortunes would have been avoided.""
 * It's not only chivalry book. Don Quixote thinks any book of fiction really happened. And after seeing two pictures of Helena and Dido, he makes this statement in Part II, Chapter LXXI:

" ...Dorothea said in a whisper to Cardenio, "Our landlord is almost fit to play a second part to Don Quixote." "I think so," said Cardenio, "for, as he shows, he accepts it as a certainty that everything those books relate took place exactly as it is written down; and the barefooted friars themselves would not persuade him to the contrary.""
 * This trope is also deconstructed: The first part of the novel was published at 1604, the second part, at 1615. At 1614, a guy called Alonso Fernandez de Avellaneda published a Fan Fiction that was a Continuation of Don Quixote, where he and Sancho Panza get severe Character Derailment. A lesser author would have ignored that Fan Fiction or denounced it in the prologue. Cervantes makes Don Quixote read Avellaneda’s Fanfiction at Chapter LIX of the (real) second part. So now Don Quixote is a Daydream Believer that believes every book is real… except the book about himself wrote by Avellaneda, that tells things Don Quixote has never done. The paradox is so great our Daydream Believer gets Bored with Insanity as a result.
 * Juan Palomeque the Innkeeper believes that Chivalric Romance books are true because TV Never Lies.

"Sancho had made his appearance in the middle of this conversation, and he was very much troubled and cast down by what he heard said about knights-errant being now no longer in vogue, and all books of chivalry being folly and lies; and he resolved in his heart to wait and see what came of this journey of his master's, and if it did not turn out as happily as his master expected, he determined to leave him and go back to his wife and children and his ordinary labour."
 * Sancho Panza, being an illiterate peasant, believes everything Don Quixote has told him about Chivalric Romance:

"Gatsby: "After that I lived like a young rajah in all the capitals of Europe--Paris, Venice, Rome --collecting jewels, chiefly rubies, hunting big game, painting a little, things for myself only, and trying to forget something very sad that had happened to me long ago."
 * In a less supernatural variant, some readers of A Series of Unfortunate Events have believed that the series was entirely true, because the Lemony Narrator said so. Never mind that the books are full of places on no known map, events which would lack Plausible Deniability, and outright weirdness.
 * To be fair, there's a lot of Paranoia Fuel which could be pretty disturbing for impressionable young readers, such as the implication that your teachers are all members of an Ancient Conspiracy which may kidnap you. The Literary Agent Hypothesis is also played up a lot both within the series and in promotional events.
 * Some Sherlock Holmes fanso.
 * Runs rampant on the official forums for Maximum Ride. Aside from the people who insist the books are true accounts by real people, there are several who claim to be similar Phlebotinum Rebels, although it's unclear whether they actually believe that part or if they're just roleplaying.
 * Many 11-year-olds were disappointed on the night of their birthdays when no green-inked letter was pushed down the chimney.
 * It's not just kids. Behold the glory of Snapes on an Astral Plane.
 * And on a darker note, there's also those Moral Guardians who take the elements from the books a little too seriously...
 * "Dæmians" think of themselves as having daemons, as depicted in the book series His Dark Materials. To be fair, saying they "believe" in daemons would be true but misleading—a lot of daemians haven't even read the books, and most just think of their daemon as sort of grownup version of an Imaginary Friend and a useful psychological tool for getting in touch with your subconscious. There are some who view it as something closer to "soulbonding" or being "multiple," though.
 * Terry Pratchett occasionally gets letters from terminally ill Discworld fans, who say they hope they will meet when their time comes. Sir Terry spends some time staring at a wall after reading these letters...
 * Similarly there are those who believe that there is an Angel who serves Death, and is a hideous monster made all of eyes, one for every human who will ever live or ever has or is right now. And when a person dies, the eye corresponding to them closes and he knows to go and thresh the soul of that person from their body, bringing the End of Days when all his eyes will be closed one little step closer. And this comes from Judaism and Islam: that's the description of Azrael, Angel of Death. Old religious ideas often seem Lovecraftian like that. Azrael appears in Reaper Man as Death of Universes.
 * Speaking of H.P. Lovecraft, a rather complicated example of Daydream Believing has happened. Firstly, the British occultist Kenneth Grant believed that Lovecraft's deities had a real existence even though Lovecraft himself did not believe in them. Later, in the late '70's a writer using the pseudonym "Simon" authored a "totally real and authentic" Necronomicon. The gullible, perhaps not taken in by the book itself, took the book's interpretation of the Cthulhu Mythos to heart, accepted their origins as actual Babylonian gods as accurate. Even the relatively sophisticated readers who acknowledge the book as a forgery have accepted the Babylonian gods theory and its fanciful elaborations on the life of Lovecraft, which contradicts known facts about his life. A number of other Necronomicons have appeared, none as influential as the first.
 * In fairness, though, most of HP Lovecraft's Daydream Believers just think that his stories are based on actual myths and legends. They're helped along by the fact that Lovecraft went to a lot of trouble to make his stories seem that way, and that he seemed pretty willing to let other writers create stories in his mythos, even during his lifetime (and actually borrowed ideas from some others, for characters like Hastur the Unmentionable). Lovecraft often had to actually state that his characters were entirely fictional creations, rather than based on the myths of ancient or modern civilizations.
 * Another example (from the mouth of Neil Gaiman, by the way) involves some man at an H.P. Lovecraft panel at a horror convention. He suggests that Cthulhu and co. are real, and use Lovecraft as a vessel of some kind, inserting their stories into his head so the world will know of them when they returned.
 * It's worth noting that Lovecraft created the Necronomicon concept because authentic medieval "black books," to which he had access, were useless to him: Vague, inconsistent (with each other and often within themselves), and tiresome, utterly lacking in any kind of inspirational qualities. That's right. The most famous single book of black magic, real or fictional, has nothing at all to do with actual books of black magic.
 * Actually, Kenneth Grant's own Typhonian Trilogies constitute a fine though hardly readable example of this trope.
 * On the subject of the Necronomicon, one of the many who believed it was real was Moral Guardian Patricia Pulling, who, in a spectacular case of Did Not Do the Research, advised police officers searching for teenage Satanists to ask teens if they or anyone they knew had taken the Necronomicon out of the library recently.
 * The Da Vinci Code. Oh good lord, The Da Vinci Code...
 * This is not at all helped by the author himself claiming that everything in the book is true. Whether or not he genuinely believes this or it is simply for publicity is unknown.
 * Mercedes Lackey has said that she has canceled convention appearances because of fans who believed her Diana Tregarde books were real. On her website she goes into considerable detail about them, and why she's both frightened of and somewhat sorry for them—and reveals that she herself, at one time, bought into a similar pattern of thinking, at least until she shook herself out of it.
 * Some The Wheel of Time fans believe that channeling is real, and that the author could have taught them how to do it.
 * There are people who claim that The Lord of the Rings is a fictionalized account of events that occurred in 3105-3104 BC. The dates can be pinpointed to the day. Some have also suggested that the Ainur, elves, and dwarves were actually Ancient Astronauts.
 * Fictional example: the short story The Gospel of Nate takes place in a universe where this turns out to be true. In fact, some people are even reincarnations of fictional characters. (It made sense in the story. More or less.)
 * Spider Robinson once told an authentically heartwrending story about a suicidal young man who called the writer on the telephone and tearfully demanded the "real location" of Callahan's saloon, apparently as a means of staving off self-murder.
 * The back inside cover of the first Leven Thumps book says that the author originally wanted his book published as non-fiction, but the publisher wouldn't do it. He came back and said he would let it be labeled fiction because getting the story out was more important. The author blurbs seem to be written in the style of a Lemony Narrator. It's most likely a tongue-in-cheek form of Literary Agent Hypothesis.
 * The Secret is all about how Daydream Believing will actually, truly, genuinely make all your wildest dreams come true.
 * Scott Adams makes a similar claim in the end of one of his books, The Dilbert Future. Essentially, he credits his fame and fortune by performing daily visualization exercises, where he imagined the outcome he wanted, then wrote a sentence asserting it 50 times on a piece of paper. He asks his readers to try it for themselves with unlikely goals over six months, asserting that it will work if you truly believe...
 * Maurice Sendak recalled that a young girl once sent him a letter asking for directions to "Where the Wild Things Are", as she and her sister wanted to take a vacation there.
 * Fictional example: Ivy Carson, in Zilpha Keatley Snyder's The Changeling, considers herself...well, look at the book's title.
 * Or wants to consider herself. Given her background she's actually being quite reasonable.
 * She was mostly raised by a great-aunt who imparted her belief in reincarnation, along with folk tales and legends, apparently presenting them as complete reality.
 * "Cullenism", a religion based on the Twilight saga.
 * After the Russian novel Plutonia (chronicling a Hollow World with dinosaurs expedition) was published in 1915, many readers wrote in, saying they were available for future expeditions. Newer editions came with a disclaimer that it was completely fictional and that the hollow earth theory was disproven.
 * A lot of Warrior Cats fans believe in StarClan, the warrior afterlife, even though the author said she made it up.
 * Fictional Example: One of the most endearing characteristics of The Great Gatsby is that he really believes all the stories in the magazines about millionaires. He believes in those so much, that he chooses them as the basis of his Multiple Choice Past as a Gentleman Adventurer, that is a Cliché Storm of various dime novels… obviously, everyone thinks they are ridiculous… at first. But given Gatsby is The Charmer, he manages to make others believe, even for a little time, in his stories. In chapter 4, he is confessing his past with the skeptical Nick:

Nick: With an effort I managed to restrain my incredulous laughter. The very phrases were worn so threadbare that they evoked no image except that of a turbaned "character" leaking sawdust at every pore as he pursued a tiger through the Bois de Boulogne … My incredulity was submerged in fascination now; it was like skimming hastily through a dozen magazines."

" "Then it was all true. I saw the skins of tigers flaming in his palace on the Grand Canal; I saw him opening a chest of rubies to ease, with their crimson-lighted depths,the gnawings of his broken heart"."
 * And after Gatsby produces a medal from Montenegro Republic and a photo of him with the actual Earl of Dorcaster, when they were at Oxford, Nick felt obligued to believe:


 * Zig Zagged in Artemis Fowl. Annoying Younger Sibling Billy Kong is told by his older brother that he needs to stay at home while the brother goes out to fight evil supernatural creatures (in reality, getting into fights with gangs, and getting out of babysitter duty). When the brother eventually gets killed in a shootout, Billy at first blames the demons, but once he grows up realizes they don't exist and his brother lied to him. Unfortunately, once he meets real fairies, he goes right back to thinking they did indeed kill his brother. His mental balance doesn't last much longer.

Live Action TV
"Those poor people!"
 * Fictional example: In Corner Gas, Davis believes that the events of Battlestar Galactica actually happened, and regularly meets with others who agree.
 * Fictional example: In one episode of Friends, Joey has a stalker (played by Brooke Shields) who believes that he is actually Dr. Drake Remoray and that Days of Our Lives is real and filmed live in real time. This leads to a funny (or disturbing) scene where she accuses Joey of cheating on her (as they had started dating) after seeing "him" with another woman on TV, and then expressing confusion over how he is on the TV and in the same room as her at the same time. The gang decide the best thing to do is convince her that Joey is actually Drake's Evil Twin, and that the real Drake lives on the other side of the country.
 * Reportedly, sometime after the premiere of Gilligan's Island, the Coast Guard received a number of letters from people asking why they didn't go rescue those poor castaways...


 * The Brazilian soap opera Escrava Isaura, which got quite a following even outside the country, resulted in many people sending money to the producers so that Isaura could "free herself from her evil master". (Said soap opera was set in early 19th century. And you'd think someone would've noticed.)
 * This kind of thing used to happen fairly often in Brazil. Actors playing the villains of the soap operas could get from merely insulted to being attacked by the more avid fans.
 * During the Doordarshan broadcast of the Ramanand Sagar Ramayana in 1987 and 1988, all India ground to a halt at 9:30 a.m. Sundays. Literally. Public transportation stopped. Even non-Hindu religious services were rescheduled. The network and studio were flooded with mail when the episode showing Sita's trial by fire aired. Viewers wanted reassurance that they hadn't actually had to set the actress, Deepika Chikhalia, on fire. In a series of special announcements, Chikhalia and Sagar explained how the effect was created. Chikhalia later went into politics and was elected to Parliament in 1991. And now, Sagar is planning a remake...
 * A similar phenomenon occurred when the Venezuelan Soap Opera Kassandra was broadcast in the Balkans; after an storyline when the poor eponymous gypsy girl heroine was Wrongly Accused there were a lot of letters to the broadcasters and the Venezuelan judicial system pleading for her innocence and saying "Please let Kassandra go free!"
 * There's a wacky woman who is convinced she's married to Sylar (or maybe just Zachary Quinto) on an astral plane. No, we don't know if it was consummated. And we don't want to.
 * These "spiritual marriages" are not as unusual as you might think, and not all the people who believe they're in one are freaked-out wackos. For one thing, medieval nuns were quite literal about being married to Christ.
 * Fictional example: On Barney Miller, a woman came to the 12th precinct, reporting that she'd witnessed a murder. It turns out she had been watching a soap opera.
 * This troper attended the University of Minnesota when Beverly Hills, 90210 (the original) was at its peak of popularity. When the series had Brenda Walsh leave Beverly Hills to attend the U. of M., a sudden rash of "Brenda sightings" were reported on campus, and this troper overheard many conversations about her supposed presence (e.g. "No, I wouldn't sit next to her, she's such a *&$%#...").
 * The Doctor Who two-parter "Human Nature"/"The Family of Blood" cleverly subverts the Daydream Believer trope.
 * In regards to Real Life versions of this trope, Peter Davison once described how he was sent a letter by a person who actually believed themselves to be the Doctor.
 * One episode of NCIS had an obsessive fan of MacGee's books start killing off people that posed a threat to his Author Avatar, eventually going after Abby (who is represented in-book by "Amy") reasoning that "MacGregor" is too good for her. MacGee manages to talk him out of it, though, by saying that MacGregor and Amy are going to get married.
 * And once the killer leaves, Abby tells MacGee that he can't marry those two characters, as it makes no sense and ignores all their previous characterization.
 * The X-Files: The episode "Arcadia" (Season 6, episode 15) features a tulpa (see above, under General).
 * The British soap Coronation Street once had a storyline where the character "Deidre Rachid" was the victim of a miscarriage of justics and jailed for a crime she did not commit. Cue national tabloids launching "FREE DEIRDRE" campaigns on their front covers and Tony Blair, the real life prime minister at the time, promising to launch an investigation. Obviously there were no real miscarriages of justice in the UK legal system needing publicity at the time...
 * In the early 1970s, a small group of Star Trek the Original Series fans in northern Kentucky planned an experimental community where they could live by the Vulcan ideals.

Pro Wrestling

 * Also... Professional Wrestling. No amount of tell-all programs and parodies will ever convince some fans that Triple H didn't really want to kill Vince McMahon. This, of course, runs the other way as well: sometimes real events happen in wrestling (hell, it happened twice to the Hart family), but some people won't ever believe that they weren't staged... One common stereotype of Professional Wrestling fans is that they're all like this, which isn't true in the slightest.
 * Stock dropped when Donald Trump "bought" WWE Raw, so some people must have believed it was real.
 * That had less to do with people believing what they saw on the show, as the WWE updating the news section of its webpage to talk about it. That would be the section dedicated to actual events, rather than which two behemoths hate each other this week. There was nothing telling the investors it was just an on-screen angle. Whoops.

Theater
"Cyrano:... —what if he be a lout unskilled? Roxane: No, his bright locks, like D'Urfe's heroes... Cyrano: Ah! A well-curled pate, and witless tongue, perchance! Roxane: Ah no! I guess—I feel—his words are fair! Cyrano: All words are fair that lurk 'neath fair mustache! —Suppose he were a fool!. . . Roxane: (stamping her foot): Then bury me!"
 * The Phantom of the Opera. When the opening line for the original novel states "The Phantom really existed," this sort of thing is perhaps inevitable.
 * For extra amusement, many characters in Gaston Leroux's original novel were No Celebrities Were Harmed versions of real people at the time, undoubtedly fanning the flames. A few of the events were based on real ones as well (the falling chandelier killing a person was based on a real accident where a counterweight did just that), as well as possibly some that the modern readers can't realize. The Phantom himself is 99% likely to be entirely imaginary, however (though some have suggested the basic idea came from a disfigured stagehand Leroux met).
 * Cyrano De Bergerac: A fictional example is Roxane, the heroine of the play. She may be reasonable in all the other aspects of life, but as a member of the preciouses movement, she is truly convinced that the romantic (fair and eloquent) heroes she has read about in the novels (particularly D'Urfe's novels, where the shepherds discourse of love with an elaborate delicacy that by no means is rustic) exist in Real Life. In fact, Roxane believes that the new guy she just has glimpsed, Christian, is one of those heroes. In Act II Scene VI, when Cyrano dares to suggest that Christian may not be eloquent, she invokes Beauty Equals Goodness. When Cyrano insists in the possibility, Roxane shows this is Serious Business to her when she invokes Driven to Suicide.

Video Games

 * There is the infamous story of some ordinary, unsuspecting people and their dealings with a cult-like society formed by "Hojo" and "Jenova", two scary-obsessed Final Fantasy VII fans.
 * Jenova's Witnesses?
 * Summoner Yuna and Sephirothslave both believe themselves to be the One True Love of Final Fantasy VII's resident White-Haired Pretty Boy.
 * Although in her most recent version of her journal, Sephirothslave claims that the one who she visits on the Astral Plane is an archangel that shares Sephiroth's name and appearance, but is completely different from the video game character. She also claims that her archangel inspired the creation of the character.
 * Yasao is a 19 years old Sephiroth fangirl who has been in love with him for around five years now and believes, one way or another, that she will one day meet him.
 * Coast to Coast AM was once pranked by a caller who posed as Gordon Freeman. The host (and presumably, many listeners) wasn't a gamer, and took it as truth.
 * Makes sense the host wasn't a gamer. Would you believe you were getting a phone call from Gordan Freeman?
 * Some girl who called herself "Link's Queen" apparently became completely and utterly convinced that she had fallen in love with Link and that the lucid dreams she had of living in Hyrule with him were a real and true second life they were leading in another dimension. She wrote a fanfiction documenting this all. The truth of this all is suspect, but given some of the stuff that goes on in the story...yeah.
 * An enormous portion of Touhou fandom falls into this trope in one way or another. For the most part they truly wish that Gensoukyou exists while realising that it doesn't, while there are plenty that insist Gensoukyou really does exist and is hidden from the rest of the world as ZUN describes.
 * A sizable portion of the Sonic the Hedgehog fandom falls into this trope. Unfortunately, it's this group of people that is considered to be one of the worst fanbases in existence.

Web Comics

 * Whether the writer of Xkcd is really paranoid about being attacked by velociraptors à la Jurassic Park is... debatable.
 * It is, however, highly amusing.
 * Another example, somewhat less amusing.
 * In this Home On The Strange, Tom purports to believe Doctor Who is real and compares his beliefs to Christian beliefs about Jesus. The script makes it clear that he's just trolling the missionary.

Web Original

 * The "Real Digimon Believers", whose Web sites all appear to have been taken offline or made inaccessible to non-members, wanted to bring about a "Digiclipse"—the opening of a portal to the Digiworld, apparently with their toy Digivices and the power of faith.
 * Pokeclipse was a Stealth Parody of the Digimon Believers intended to Troll them. Turned out, to their sad surprise, that there are people who really did believe in the real-world existence of Pokémon and that scientists are trying to create them or something.
 * Actually, they made Pokeclipse knowing full well that there were those who would probably believe them. Their plan was to gather a large following of genuine believers, which would then be tricked into raiding Digiclipse for them.
 * The Fandom_Wank mockery community has a page listing their historic mockeries of soul-bonders and otakin.
 * Snapewives.
 * In the same vein as the Snapewives, there was a fun report about a woman who believes that she is married to Sylar, the serial killer from Heroes, on the astral plane, and her 12-year-old sister channels him for her.
 * Above and beyond that, there's a guy who, by his own account, married someone's Sonic the Hedgehog Fanfic Character on the astral plane. And he can also do Ki Attacks. Apparently.
 * Engi no Jutsu is a Naruto roleplaying site, (in)famous for its draconic policies, snarky members and massive amount of rules (for a PBP site). All of it a reaction to the overwhelming Fan Dumb in the Naruto community. At one point, one of the Admins complained that he was receiving requests to join the "elite member" pseudo-moderator group with motivations along the lines of "I want to be a real ninja someday."
 * Speaking of the Furry Fandom, the online comedy personality "2 the Ranting Gryphon" seems to have fallen into belief of his own outrageous claims of controlling a "furry Illuminati", going so far as to arrange a Secret Test of Character on one of his fan forums a few years ago to weed out who among his audience could keep a secret and, thus, were worthy enough to join (the test: keeping quiet about the details of a "social disobedience" assignment the Gryphon posed to his fans, of which you could only learn by emailing him; it failed miserably, because none of the participants realized they were being tested on their silence instead of their ability to complete the assignment, and had a brief argument on the forum over how a lack of proper materials prevented them from completing it). Ironic, considering he had ranted before on the very same Daydream Believers mentioned above.
 * Then there's the listeners of his shows who honestly believe they are soldiers in his "real-life Furry Army of Doom". Not surprisingly, many of them got duped into the aforementioned Secret Test of Character... and failed miserably.
 * Lucy, Patrick and Emily from The War Comms are a parody of this trope.
 * There was a forum post on Starman.com which stated that, since aliens might exist, then the events of EarthBound could really happen. The poster then claimed that he had actual Psychic Powers and could make a ball of electricity in his hands or something like that. It is unknown if the poster was serious or not.

Western Animation
"Egon: Even though there was never a real Sherlock Holmes, millions of fans believe in him. Ray: Right! The London post office gets thousands of letters every year addressed to Sherlock Holmes. Peter: Well, this is just great! I mean, who are we going to be fighting next, Darth Vader?"
 * The Real Ghostbusters used this trope in-universe to explain how ghosts of Sherlock Holmes, Dr. Watson, and Dr. Moriarty showed up in New York City. Apparently, enough daydream believers will actually give rise to the characters through "belief made manifest."


 * Referenced in the Aqua Teen Hunger Force episode "Dumber Dolls" (quoted above), where Master Shake claims "The Highlander was a documentary, and the events happened in real time."
 * In Home Movies "Renaissance" episode, Melissa explains her preference for the Medieval Fest over the Sci-fi Fest based on medieval history being real. Jason argues that sci-fi stuff is real too. Coach McGuirk later insists that the medieval people and the sci-fi people have been battling each other for thousands of years.
 * The entire premise of the movie Bolt is that Bolt really believes he's a superpowered dog. They even shoot each episode in one shot.
 * There's at least one person who is convinced that the characters in Disney's Beauty and the Beast are real, which somehow is proof that the direct-to-DVD sequel is evil (not to say that said sequel doesn't have its problems, but really). This person also seems to think that anything that contradicts the movie's canon is terrible and thus hates Lilo and Stitch, solely because of the trailer in which Stitch knocks down the chandelier during the ballroom scene. All because "this is obviously not what happened in the film. Apparently, it's meant to be a joke, but it's a genuinely mean joke. It's not funny at all. They danced in that ballroom without interruption. That is an indisputable fact known to be true by everyone who has seen the movie. The scene has already HAPPENED. Therefore the ad is meaningless."
 * On Kim Possible, Timothy North and the actor who played the villain Whitestripe in "The Fearless Ferret" believe their show was real and act accordingly.
