What's a fear you used to have as a child that looking back on as an adult is funny?

I was deathly afraid vampires were going to sneak into my house at night and give me the S U C C. So I used to sleep with a pillow around my neck, as if ol' Count Drac couldn't just yank the pillow away. I also fully believed vampires couldn't come inside unless invited in but that logic didn't get in the way of me still believing they were going to break in somehow.
