I believed (kinda still do...) that there was a slow monster and a fast monster. If you moved slow, the slow monster would eat you, but if you moved fast, the fast monster would eat you. It was a no win situation. Grrr...
I also believed that if you would stay totally under your covers, that you would be safe from the monster looming over your bed. Of course, after a while I couldn't breathe and the monster always seemed to come on hot summer nights. I sweated the bed wet, but still wouldn't take the covers off. WEird.
