I'm terrified of horror movies, even the really bad ones that most people don't consider scary. Once, my dad convinced me to watch a scary movie with him. Bad idea on my part. My dad claimed it wasn't scary in the least. I had fear induced insomnia for the next two days.
I'm also afraid of big spiders, like those daddy long legs. Little ones don't scare me at all, but the big ones, even dead ones, terrify me.
