Falling asleep in the bath in a bad idea at the best of times, but when Freddy Krueger is creeping about, it makes it about thirteen times worse. Luckily when all girls fall asleep in the tub, they do so with the grace and dignity of having their legs spread eagled just waiting for Freddy to think it would be rude not to place his hands right between them... Anyway, as irrational as it seems, this scene means you're probably now terrified of that clawed hand ever appearing between your legs and pulling you down into that hellish sub-pool that is definitely magically beneath your bath.
