OH yeah. I've slapped more imaginary bugs in the last few years than inhabit a cheap hotel. Usually they are on my legs or along the part in my hair, sometimes on my forehead. Once in a while other places, but those are the most common. Sometimes I've whipped the blankets off at night because I just KNEW this time it was a real bug. Nope.

And it does feel just exactly the same as real bugs. I can be staring right at a spot on my skin and see nothing there, and still feel "it" or "them" crawling around. Argh.
