Never Wake Up a Sleepwalker

Did you know what waking up a 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.

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.
