Uh, I don't like horror/haunted genre, so these may be totally 'old hat' but I'm spooked by:

creepy sensation, especially when I can't see what's touching me. (Particularly when it's dank...)

clowns. (What's going ON behind that mask/makeup...)

feeling peeled grapes when you don't know what they are

strobe lights (disconcerting)

taxes and overdue bills, but I suppose this is a REALLY useless suggestion, even moreso than the above.



Good luck
