This is what not to do... when I was little, I told my sister the midnight crocodiles lived under the bed. If she was not in bed, asleep, by midnight the crocodiles would eat her up. Even if her hand was dangling over the edge of her bed they'd eat that. And oh no, it's almost midnight! Got her back into bed quickly enough so I could get to sleep. My poor sister was terrified of the midnight crocodiles for years! (I think I was 8-9, sister was 6-7.)
