Nearly everyone has had an experience where they've dozed off, or almost dozed off, at an inopportune moment. However, a select few of us, both in real life and in fiction, raise this odd habit to an art form, becoming the official Sleepyhead of their social circle.

These characters have a habit of nodding off anywhere, at any time. They constantly end up at the last stop on the train/bus because they fell asleep on the journey, the teacher routinely throws things at them because their snoring is getting in the way of the lesson, and their friends spend half their lives prodding them awake...or at least hauling them into a vertical position so that no one notices that they're actually unconscious.

There are two main character types that are prone to having the sleepyhead trait. The first is the CloudCuckoolander, and it's part of their social inappropriateness schtick. They couldn't care less if they get caught sleeping, and may complain about being disturbed. Other characters, however, often yell at them and tell them to be more responsible.

The other sleepyhead is the hardworking-but-kinda-dim character, and unlike their more eccentric cousins, this is a source of major embarrassment for them. They'll blush and stammer when woken up, but by contrast, other characters usually see it as an endearing trait. Unlike the CloudCuckoolander, whose snoozle-fits reflect their dissatisfaction with/divorce from reality, the implication with an earnest character is that they put so much of themselves into everything they do that they wear themselves out.

Both types will have exaggerated reactions to the things that naturally cause sleepiness, like a full stomach or a warm day. In anime at least, this character tends to be female.

These characters seem to sleep pretty well at night. Characters who pull all-nighters and then go thwump at an inopportune time don't come under this trope — that's just exhaustion, while a sleepyhead will get a good eight hours and still doze off in Biology class. The sleepyhead really likes their bedtime, and under times of stress will usually be heard complaining that they're tired, or longing aloud for a pillow. Their bedroom is often filled with creature comforts, tons of stuffed toys, and the world's comfiest bed.

Occasionally they will actually have narcolepsy, or another real-life medical condition causing [[http://en.wikipedia.org/wiki/Excessive_daytime_sleepiness excessive daytime sleepiness]]. Usually not, though.

A Sleepyhead may or may not be a HeavySleeper. They're probably NotAMorningPerson as well — the eccentric type will be grumpy, and the earnest type completely out of it when the alarm clock goes.

!!Examples:

[[foldercontrol]]

[[folder:{{Anime}}]]
* Nemu in ''HaibaneRenmei'' is the queen of this trope. Even in her character-defining "cocoon dream," she was snoozing. She's closer to the earnest version of the trope, though in actual fact she's more [[CloserToEarth organised and reliable]] than other versions, on top of being a sleepyhead - other characters comment that her dependability is ''why'' no-one minds that she sleeps all the time.
* Phonsekal Laure from ''TowerOfGod'' is an absolute master of grabbing sleep everywhere. He sleeps not only during lessons and non-combat tests, but also during deathmatches. He runs around with his pillow and SecurityBlanket and after minimum effort he drops to the ground and takes a nap. The only way he usually can be arsed to do something is by taking those two items away.
* Yuno in ''Manga/HidamariSketch'' is the earnest variant of the trope. Her GeniusDitz neighbour Miyako is normally hyperactive, but she also dozes off frequently, especially in afternoon classes (post-lunch being tough on the BigEater Miyako), making her the CloudCuckoolander version.
* ''Manga/GAGeijutsukaArtDesignClass'', also in a high school art setting, we have Kisaragi who, like Yuno, is an only-moderately-talented but hardworking sleepyhead.
* Mihoshi in ''Anime/TenchiMuyo'' likes her naps.
* Osaka in ''Manga/AzumangaDaioh'' is the definitive CloudCuckoolander version, indulging in her bizarre dreams during class.
** At one point, while under a kotatsu, she declared that it was so comfy she could fall asleep. Then she used Chiyo's large Chiyo-dad plushie for a pillow, laid back, and...
-->'''Chiyo:''' Wow, she ''did'' fall asleep!
* Keiichi, the cellist of ''[[KiniroNoCorda La Corda D'Oro]]'', seems to spend more time asleep than he does awake. He's a male {{Cloudcuckoolander}} (or, more accurately, BunnyEarsLawyer) version.
* Aoi Sakuraba from ''Manga/AiYoriAoshi'' does this right at the start of the series when she meets with Kaoru. They board a train and needed to get off at the next stop, but Aoi was so exhausted that she fell asleep on Kaoru's shoulder and they ended up circling around back to the stop they originally boarded on. Kaoru woke her up by the time their destination came by again.
* Konata from ''Manga/LuckyStar'' sometimes falls asleep in class. When Miss Kuroi calls on her name and snaps her back awake, Konata instinctively tries to defend herself by saying she wasn't sleeping. If she had just kept her mouth shut, she would have been fine. However, since Konata's daytime drowsiness can partly be contributed to her staying up late [[OtakuSurrogate playing games or watching anime]], this is a partial aversion.
** Tsukasa is a straight example for the earnest type, together with a cuddly bedroom and being a HeavySleeper.
* Sloth from ''Manga/FullmetalAlchemist'' tends to fall asleep even when people are threatening him.
* Greece from ''Manga/AxisPowersHetalia'' sleeps a lot and at random times, although he is more laidback than CloudCuckooLander or embarrassed. He even falls asleep once in the middle of a conversation, and then looks bemused when he wakes up soon after.
** Italy shows this occasionally. At one point, he even falls asleep while Germany is lecturing him for being too lazy. This is also lampshaded in the dub, when Japan signs the agreement to ally himself with the Axis, and notices that Italy has zonked out at the heated table they're sitting at.
--> '''Japan:''' He appears to be sleeping.
--> '''Germany:''' Yeah, that is kind of his thing.
* Yoshimori from ''{{Kekkaishi}}''. Justified in that he has to go to school, do chores at home, ''and'' fight Ayakashi every night.
* Nayuki from ''{{Kanon}}'', besides being a memetic HeavySleeper, is also this. Yuuichi regularly wakes her up at the end of class.
* Saiga from ''LegalDrug'' spends most of his time sleeping at Kakei's store, even when he's supposed to be watching the till. [[WildMassGuessing There has been much speculation as to why]].
* Yakumo, from ''Manga/SchoolRumble''. Random classmates are prone to staring at her whenever she falls asleep on the bench outside school.
* Portgas D. Ace of ''Manga/OnePiece'' has rather intense narcolepsy and tends to fall asleep in the middle of talking or eating, leading more than a few people to think he suddenly dropped dead.
** The narcolepsy is evident in his family [[spoiler:(albeit it's more likely habitual given he's an adopted member)]], as shown with main character Luffy and their grandfather Garp. All three of their cases really just crop up for RuleOfFunny though.
* Yoshihito Usaida from ''Manga/GakuenBabysitters'' spends about half of his time in the manga being the ButtMonkey to the children of the daycare. The other half is spent sleeping anytime and anywhere on the job.
* Kumin in ''LightNovel/ChuunibyouDemoKoiGaShitai'', who brings her pillow to school to nap and can fall asleep at will. She even tries to establish a napping club. Her ImageSong is all about how she loves to sleep, and even ends with her sleepily singing "good night~".

[[folder:ComicBooks]]
* In ''[[MarvelAdventures Marvel Adventures Avengers]]'', IronMan was once caught sleeping during a CaptainAmerica movie. He wasn't caught until the end because of his helmet. The only reason that anyone noticed was because of his snoring.
* In ''ComicBook/ReidFlemingWorldsToughestMilkman'', Reid's best friend Cooper (aka Captain Coffee) is found sleeping at almost every opportunity--during roll-call, before lunch, after lunch, or pretty much whenever he can.
[[/folder]]

[[folder: {{Film}}]]
* [[ExactlyWhatItSaysOnTheTin Sleepy]], in ''Disney/SnowWhiteAndTheSevenDwarfs'', is an obvious example.
* Steve-O from the ''[[{{Jackass}} Jackass and Wildboyz]]'' movies and TV show fits this as well. He was attacked by the "Black Mamba," hair trimmers, and thrown from a moving boat due to this.
* Sleeping Beauty in ''[[{{Shrek}} Shrek the Third]]'' is portrayed as having narcolepsy.
[[/folder]]

[[folder:{{Literature}}]]
* The Dormouse in ''Literature/AliceInWonderland'', natch.
* Clovis and his half-siblings in ''TheHeroesOfOlympus''. Justified as they're children of Hypnos, the Greek god of sleep.
* Lieutenant Mercadet, from Fred Vargas's thriller novels, is hypersomniac and frequently sleeps at work ; at one point, he even put pillows on his desk to make his naps more comfortable, since he cannot stay awake more than six hours in a row. His hypersomnia is used as a plot point in ''L'Armée Furieuse'', [[spoiler: when Commissaire Adamsberg makes everybody (Mercadet himself included) believe that he fell asleep while watching Momo-Mèche-Courte, in order to let him escape from the police station.]]
* Lazy from ''Literature/SomeoneElsesWar'' is this trope UpToEleven. It's implied that he ''does'' have narcolepsy, but that doesn't mean anyone takes him seriously.
* WaysideSchool student Shari is known for falling asleep during class. Mrs. Jewels allows this because she believes in SleepLearning. In Shari's debut chapter, she even slept through ''falling thirty stories'', waking up only when Louis caught her. When the school was closed because of the cows (DON'T ASK), and all of the kids were sent to different schools, the first thing Shari said when returning at the reopening was "Now I can get some sleep!"
* Mr. Benedict in TheMysteriousBenedictSociety has narcolepsy.
[[/folder]]

[[folder:LiveActionTV]]
* Patrick Jane from ''TheMentalist'' takes frequent naps, even while on duty. However, it's implied that these are practically the ''only'' times he sleeps.
* Sgt. Rizzo from ''[[{{MASH}} M*A*S*H]]'' was often observed under the carriage of a jeep; however, he was rarely working on them as using them as an excuse to get a secret nap in.
* ''Series/{{Noob}}'' has Ivy, who frequently falls asleep in front of her computer and always sounds tired when she's awake. A recent episode revealed that she actually suffers from narcolepsy.
[[/folder]]

[[folder:NewspaperComics]]
* [[{{Peanuts}} Peppermint Patty]] is notorious for falling asleep in class. She actually goes to a narcolepsy clinic in one strip and ''dozes off at the reception desk.'' However, nothing comes of it.
** Funnily enough, the only time she is actually wide-awake in school is on the last day of class before summer vacation.
* {{Garfield}} has [[http://www.garfield.com/comics/vault.html?yr=1978&addr=781106 "nap attacks."]]
* Bucky, from ''GetFuzzy'', tends to pass out quite a lot. Among other things, him reaching a certain boiling point of anger makes him fall asleep. Rob and Satchel know about this, and comment that it's sometimes better to just deliberately invoke it than to try and calm him down.
[[/folder]]

[[folder:VideoGames]]
* Cammy Meele of the ''AceAttorney: Investigations'' game, has the horse-like ability to sleep while standing up, and has to be constantly prodded into consciousness when you interview her. This is particularly annoying, even more so when [[spoiler: you realize she's faking it]]. Yanni Yogi pulls this off as well [[spoiler: and again, he's faking it - Phoenix and Edgeworth seem to be able to summon faux-sleepyheads on command]].
* The [[HelloInsertNameHere Main Character]] of ''[[{{Persona3}} Persona 3]]'' has the option of dozing off during a good portion of his classes. Upsides include improving your condition and recovering from sickness faster. Downsides include the possibility of missing information that comes up during exams (and don't think you can use the Internet to get the exam answers: if you didn't hear it in the game, you don't get the option of answering it).
** In the manga adaptation, he's depicted as being drowsy most of the time, and is described as "zoned-out" by the other characters. Though he can switch to HyperAwareness if it’s really important, like discussions and Tartarus battles. [[ArsonMurderAndJaywalking Or he just wants to win that ping-pong match against Akihiko-senpai.]]
* General Haar from ''VideoGame/FireEmblemTellius'', and also Treck from FireEmblemElibe and Forde from ''VideoGame/FireEmblemTheSacredStones''.
* Siegmeyer of Catarina from ''DarkSouls'' can be found asleep (while standing up, no less) in several improbable and dangerous places. Kingseeker Frampt also enjoys the occasional power nap, requiring you to hit him once to wake him up(but ''only'' once).
* ''SkywardSword's'' Link apparently always had to be woken up by Zelda, and his sleepiness is actually [[GameplayAndStoryIntegration incorporated in gameplay]], as he will start to nod off if you have him sit down for too long. Partly this is used to give him a GoodMorningCrono opening in some games, and explains why he's a HeroicMime, but all that sleep seems to do him good, because once he's up he can stay awake for weeks at a time if need be.
* The gym leader Erika from ''{{Pokemon}}''. In-series magazine ''Pokemon Journal'' states she can often be seen sleeping and her Fame Checker message has her falling asleep at the end. All of her pre-battle quotes having her nearly falling asleep and her original sprite seems to have her sleeping. Popular {{Fanon}} has her being narcoleptic.
* Riki of ''VisualNovel/LittleBusters'' is one of the kind that actually does explicitly have narcolepsy. Treatment of it varies - sometimes it just kicks in to drive scenes or fuel unrelated drama, but at other times the way falling asleep randomly and uncontrollably can be incredibly limit the things one can do in life is explored more seriously.
* In ''Soma Bringer'' Forte referred to Millers as "Chronic Sleepyhead Millers."
[[/folder]]

[[folder:{{Webcomics}}]]
* In Webcomic/GreyIs Black frequently calls White this. He sleeps in late (in comparison to Black) and is always ready to take a nap during the day if he can find the time.
* Lillian Tallis of GoGetARoomie. She is a [[{{Hikkikomori}} recluse]] who love nothing more in the world than sleeping and dreaming. She is SUCH a sleepyhead, it's implied she forgets to eat because she's spending all of her time sleeping. Her brother calls her Lazy Tyke. A nickname Roomie took next to no time to adopt.
* Hannelore Ellicott-Chatham of Webcomic/QuestionableContent.
[[/folder]]

[[folder:WesternAnimation]]
* Snoozy on ''ThePerilsOfPenelopePitstop''.
* Bedtime Bear of the ''CareBears''.
* [[MeaningfulName Sleepy Bat]] on ''{{Birdz}}'' is somewhat of a type 1, except that he doesn't usually get called out for it.
* Astra from ''LiteSprites'' fits the CloudCuckoolander type.
* TheodoreTugboat had the recurring character of Northumberland Submarine, who is even referred to as "the sleepy submarine" and was very rarely seen without his eyes half-shut or closed entirely. It was explained that this was due to him largely working at night (in fact one episode had Theodore and Hank working late and being ''genuinely shocked'' to find him wide awake), but it still gets pretty extreme- at least once he fell asleep ''mid-sentence'' while talking to Theodore in the ''middle of the harbour'' and on another occasion he fell asleep while surfacing with his head just barely sticking out of the water.
