My creepy crawlies seem to be random, not related to weather or other symptoms. I wish I had a nickel for every time I said "I'm NOT going to look, there's nothing there!" Then I have to look ANYWAY, because what if that's the one time there really IS a bug or many bugs crawling on my scalp/leg/forehead/hand or whatever?

And, as has been mentioned, there is always the dreadful possibility that it could be both real and (shudder) a spider. Gak.
