Did you know that waking up a [[{{Sleepwalking}} Sleepwalker]] will cause severe shock, and even DEATH to the person?

Well... no, that's not actually true - it's an old wives' tale that still persists despite scientific evidence to the contrary. However, in TV-land, no one has heard this update (and some media predate this myth being busted) and will continually dance around whatever strange or frightening behaviors the sleeper exhibits.

Never mind that the sleepwalkers half the time tend to wander off into pretty dangerous situations completely unawares, where one would think that waking up the person would be much less dangerous then risk slipping up and letting that one crocodile eat them.

[[TelevisionIsTryingToKillUs But nope. It's too dangerous.]]

To add insult to injury, the sleepwalker will often walk right into bed, and wake up bright-eyed and bushy-tailed while their companion collapsed from exhaustion.

* In ''PowerPack'', the children bring Franklin back to Avengers Mansion after witnessing the Morlock Massacre. When the adults find out about this, Franklin claims he was sleepwalking, and the other children say that they didn't wake him because it would be dangerous.
* One ''[[ArchieComics Archie]]'' comic has Jughead, for some unexplained reason, sleepwalk through almost all of his entire school day. To avoid waking him up, the teachers give all of their students tests. During lunch, Jughead stays asleep but eats the food off of everyone's trays. He eventually wakes up when the school bell rings, suffering from no ill effects. The other students aren't very happy.

* In ''SecondhandLions'', the warning is more for the safety of the person waking the sleepwalker, than that of the sleepwalker himself. When Walter tries to wake his sleepwalking great-uncle Hub, his other great-uncle Garth pulls Walter's hand back and says, "Don't. Last time I tried to wake him he nearly tore my head off."

* One ''Series/AllThat'' sketch was built around this, with a teacher being repeatedly told not to wake up a sleepwalking student, in spite of him doing some incredibly bizarre things. By the end of the sketch, however, it's implied he was only faking it.
* Averted in ''Series/DesperateHousewives'': Susan finds Orson standing on her front lawn naked and muttering to himself. Once she figures out he's sleepwalking, she slaps him awake.
* In ''Series/ElChavoDelOcho'', Doņa Clotilde and Doņa Florida are seen sleepwalking and Don Ramon refused to wake them up or even disturb them recalling that it'd be bad for them. El Chavo later abuses this by pretending to sleepwalk in Kiko's house to take some bread.

[[folder:Web Comics]]
* In ''Webcomic/GirlsNextDoor'', [[ThePhantomOfTheOpera Erik]] advises [[{{Labyrinth}} Sarah]] not to wake Christine when she finds her sleepwalking toward his room for some late-night music lessons.

* Daisy Duck once had to race ahead of her somnambulist boyfriend [[DonaldDuck Donald]] to remove obstacles out of his way, which considering he was doing gravity-defying tricks such as climbing up walls, was quite a feat.
* Bluto and {{ComicStrip/Popeye}} had to [[EnemyMine join forces]] to save Olive Oyl from herself in "A Dream Walking", especially once she wandered into a construction site.
* One ''[[WesternAnimation/LooneyTunes Merrie Melodies]]'' short involved a Fox disguising itself as a Guard Dog using this trope to smuggle chickens out, counting on the real Guard Dog's fear of causing him to his advantage.
** Another, "The Unbearable Bear" featuring Sniffles the Mouse, involves a policeman chasing a burglar in his own home, but both parties trying to stay quiet because the policeman's wife is sleepwalking. Though it's more because they're both afraid of what she'll do to them if she wakes up.
* This was the main plot point of the ''TheAngryBeavers'' episode "[[Recap/TheAngryBeaversE26FoodOfTheClods Food of the Clods]]".

[[folder:Real Life]]
* In RealLife, the myth originally began from the belief that soul separates from the body during sleep, and waking up a sleepwalker would separate them from their soul, potentially with all kinds of horrible results. While the myth has been debunked in practice several times over, it does still apply in situations where a sleepwalker ends up in dangerous locations, like an edge of the roof, in which case the shock may well end up killing them, albeit indirectly, as they stumble in panic.
** Which only goes to underscore the importance of waking the sleepwalker before they get into such a dangerous situation in the '''first''' place.
