What was your most irrational fear as a child?

[33girl]

Being trapped in a car and going backwards down the hill on the main road by my house. I still get a little nervous if I have to back down a hill.

And when I was 8 we had this book in our class reading corner that had a picture of a troll/zombie monster in a graveyard. It totally freaked me out. I was convinced it was going to sneak into my room at night between the drapes and get me if there was any light shining through the 2 panels. I still make sure the drapes are completely shut.

And I'm not sure if this qualifies as a childhood fear, but as a teenager, I was terribly afraid The Bomb would drop and I'd die a virgin.
