Mine is werewolves. Seriously. I know they don't exist, I know I can step outside in the dark and stroll through a forest. But damn, sometimes I feel like I'm being watched by one of those creatures waiting to pounce me and rip me to pieces. Hell even the cheesiest werewolf horror film creeps me out. I think it comes from when back when I was a kid where I saw a book with a werewolf on the cover of it, looking directly at me with its mouth open ready to eat me.
