When I was really little, I used to pull the covers up to my neck before I went to sleep. I figured that if someone broke into the house and came into my room, they wouldn't hurt me because OBVIOUSLY I was just a head on a pillow. Since the rest of me was covered, no one could tell that it existed except for me.
