Asleep for Days

The best way to underline that a character has just been through a particularly harrowing experience is to have them wake up in a bed and be told that they've been Asleep for Days. If you want to throw some Ship Tease into the scene as well, you can also have the character's Love Interest sleeping next to his or her bed, having exhausted him/herself watching over the sleeping character.

There is a kernel of Truth in Television to this, as recovery from any particularly grievous injury or sickness (or simply fatigue) can occasionally demand tens of hours of sleep. Sometimes writers can get a little off mark though, unceremoniously describing characters as having slept for weeks or months on end when such long periods of unconsciousness would most likely get a person admitted to an intensive care unit for coma treatment in Real Life. Even if a character isn't literally unconscious the entire time but was merely bedridden or delirious, they would require extensive rehabilitation due to muscle atrophy before they were able to chase the Big Bad across the world or spring back into action defeating the evil vizier's mooks in hand-to-hand combat again. A person who cleanly awakens from this without the benefit of a nursing staff and a bedpan is certainly invoking the trope of Nobody Poops.

Usually a form of Deep Sleep. When they wake up, they'll likely comment on the Unfamiliar Ceiling.

Rip Van Winkle is the extended version of this trope.

Anime and Manga

 * Saito sleeps for three days after his first duel with Guiche in The Familiar of Zero.
 * When Kyon in The Disappearance of Haruhi Suzumiya, he awakens in a hospital room, having apparently been sleeping away a bad concussion for days.
 * Athena in Saint Seiya spends most of the series fliping in and out of this state.
 * In One Piece, Luffy sleeps for three days after defeating Crocodile. After he's told this, he calculates that he missed 15 meals. This apparently has been happening to him so constantly he learned to eat whilst unconscious in order to not miss those meals again.
 * Zoro, after taking in Luffy's pain, combined with his own injuries against Oz, was asleep for quite a few days.
 * Happens to Keroro in the 100th chapter of Keroro Gunsou, "The Frog That Lost New Year's", after partying a little too hard on New Year's Eve.
 * Happens a few times in Saiyuki after major injuries, the longest would probably be Hakkai after Gojyo shoves his guts back in.
 * This happens with a bit of frequency in Ciel: The Last Autumn Story, as a result of witches overusing their magic powers. Yvienne, the main character, undergoes it at least three times over the course of the series.
 * Yurie often falls unconcious after overdoing things with her powers; she was once out for days after granting a huge stack of school improvement wishes simultaneously.
 * In Bleach Ichigo ends up asleep for a month after.
 * In the Lupin III movie The Castle of Cagliostro, Lupin sleeps for three days after being severely wounded in a fight with the Big Bad. He's distressed to find that this is the case, because it means he might be too late to save the day, and demands large amounts of food so he can get his strength back quickly.

Comic Books

 * Spider in Transmetropolitan got knocked out, came to and demanded a machine so he could write a promised column, and was told he'd been out for four days. This leads to one of the series' Crowning Moment of Heartwarming when Yelena goes on to say that she'd written it for him and submitted it, flinching as she expected his wrath. He kisses her on the forehead instead and thanks her.
 * Occurs fairly often in Usagi Yojimbo, either due to surviving a grueling journey or encounters with poisons, monsters, and demons.

Fan Works

 * In 'Blessing in Disguise' Peter awakes in a hospital bed after five days of being in a coma, and proceed to Freak-Out when he found that he was.
 * In the Pokémon fan comic Rescuing Dara, the titular Dara sleeps for 3 days straight after her kidnapper drugs her with Sleep Seeds.

Film

 * In the movie version of How to Train Your Dragon Hiccup wakes up several days after the final battle with Toothless watching over him.
 * ...And then is so excited that Hiccup is finally awake that he bounds around the room, one of his leaps being on Hiccup's stomach. This is funny when a twelve-pound cat does it. Toothless, I'm willing to bet, weighs a heck of a lot more than twelve pounds.
 * In Mystery Science Theater 3000: The Movie, Crow jokes that the departure of Cal Meachum prompts Joe to sleep off his depression: "I'm gonna curl up in his sock drawer and sleep for days."
 * In In Harm's Way, Admiral Rockwell Torrey is badly wounded in a sea battle and wakes up in a hospital ship next to his love, Maggie Haynes, as head nurse. (Who, somehow, always seems to be assigned to where he is.)
 * In the first Harry Potter movie, Oliver Wood tells Harry he was knocked out for a week after taking a Bludger to the head during his first Quidditch game.
 * Jason after his  in Mystery Team; this is merely implied.

Literature

 * In the Doctor Who Eighth Doctor Adventures novel The Adventuress of Henrietta Street, the Doctor's heart is torn out. (It's okay, he has another one.) He consequently sleeps for a week, and wakes up still visibly wounded but mostly healed, with his friends by his bedside and "an enormous smile on his face". Awww.
 * Happens to Frodo twice in The Lord of the Rings: once in Rivendell, and once after being rescued from Mount Doom.
 * During his encounter with Quirrell at the end of Harry Potter and the Philosopher's Stone, Harry falls unconscious and wakes up in the hospital wing three days later.
 * In Shatterglass, Tris exhausts her store of magical power (not such a great idea, btw) and as a result sleeps for a week. Literally. This is pretty consistent across both of Tamora Pierce's universes - exhaust your magic, and fall asleep for quite awhile.
 * In Trickster's Choice, Kyprioth keeps Aly asleep for five days, then again for three more in Trickster's Queen.
 * Her mother Alanna, like Tris in the above example, very often overuses her magic and knocks herself unconscious. She usually prefers the nonmagical solutions, but when she does bust out her magic, she really busts out her magic.
 * At the beginning of the book Force 10 From Navarone by Alistair MacLean, Miller tells the bosun of the ship they had just boarded after escaping from Navarone to not wake them until they reached Cairo. The bosun points out that they won't reach Cairo for another two days. Miller replies "I know."
 * In L. Jagi Lamplighter's Prospero Lost, Miranda passes out before they reach the North Pole and sleeps for three days. Mab wishes she could have slept one more.
 * Occurs a couple of times in Mistborn, when Vin uses pewter to compensate for fatal blood loss.

 * Disgaea: Hour of Darkness ramps this Up to Eleven, with Laharl planning for a ten-day "nap" and being asleep for two YEARS.
 * Portal 2 also takes it Up to Eleven, with Chell apparently being asleep for many years after the events of the first Portal. Well, actually the computer that tells her how long she's been snoozing for glitches out, but we can clearly see that
 * Used in both Knights of the Old Republic games. In the first, the Player Character was injured while fleeing in an Escape Pod which crashed. S/he has been "in and out of consciousness for days" with Carth watching over them and tending to their wounds. The Estrogen Brigade really liked the scene. The second, like everything else in the game, is more sinister..
 * Celes in Final Fantasy VI has been asleep for a whole year taken in care by Cid after
 * Tifa in Final Fantasy VII has been asleep for a week following the escape from the crater and the impact from the WEAPONs. She and Barret are awaited for execution in Junon.

 * Avatar: The Last Airbender. Aang is knocked unconscious by Azula's lightning bolt so long that his hair had enough time to grow back. He definitely isn't well when he first wakes up, and only Katara's extensive healing let's him recover so quickly.

Real Life

 * Kleine-Levin Syndrome, although in this case the cause isn't stress or injury.
 * Some centenarians, particularly those who make it to 110 and over, tend to sleep for a few days at a time as they get on towards the end.
