What is your phobia?

I am really afraid of spiders. They just seem so creepy to me! I never really used to feel that afraid of snakes, although my husband recently found a snake that had somehow gotten into our house, so now I have been really paranoid about snakes recently! Fortunately, I just happened to be out of town that week, so I didn't have to see it, but it still freaks me out to think about it! I'm so nervous it will happen again! Anyway, those are the things that scare me the most.
