This may seem weird, but as a kid I was terrified by flushing the toilet at night. It was loud and I always imagined a vampire hearing it and coming after me. Strange, I know.
Vampires used to scare the bejesus out of me. I don't mean Twilight vampires, I mean the ones from classic horror movies. That being said, I remember watching a vampire movie with the family, and a women vampire suddenly came alive while a spike was in her, and I ran down the stairs. My dad had to say "What would Luke Skywalker have done? That's right, he'd have cut his head off. It's fine". What makes it more embarrassing, is I think I remember the movie and watched it recently. It was Dracula: Dead and Loving It starring Leslie Neilson...
