I'm hosting my usual Halloween party, and I've set the theme to be "Fear", asking people to wear "Phobia" inspired costumes. I'd like to do something freaky, instead of campy, but I don't have any good ideas besides a scary clown. Anyone got any ideas of a good phobia with potential for a scary costume. Basically I'd like it to be the kind of costume that would scare someone who had a phobia about whatever I dress up as. Or maybe give someone a phobia.
