What freaks you out?

Do any of you have silly little things that you hate. Like the feeling of wet paper makes me cringe. Plasters make me feel dirty, I can't use them at all, gem infested horrible things. Seen somebody chew tinfoil makes my teeth hurt. Micro-fiber cloths make my skin itch. Just silly little things that for no reason at all, freak you out thinking about them. Or am I just a weirdo?
