Might sound funny but I'm afraid of clowns. They're really creepy. When we went to a birthday party with clowns, I stayed outside and ate there as well because there were 2 clowns. They really freak me out.
I don't really know if this is a phobia but I don't like to turn when I'm sleeping. It seems like there'll be a ghost staring at me or something. That's why I always face the wall when sleeping. I developed this when I read something on CreepyPasta.
