Cindy So, this may sound really dumb, but I actually got bit by one of those things at about 2:00am this morning. I screamed myself awake and lay in bed for several minutes with a throbbing finger. The initial pain -- very REAL pain in spite of the imaginary bite -- and then the trauma of realizing that an imaginary event could cause actual physical discomfort was enough to keep me from getting back to sleep for a very long time.
