In greek we call them Baboula, and my brother and i had a bunk bed...he used to pretend he was the baboula and it scared the crap out of me.
I was my sister's Baboula!!! I was doing some noises to scare her...:bgl:
About mine...I thought there were dragons with large nails flying around our house, so I always closed the window and didn't had any lights on so the dragons couldn't see me...
