Say for example, my left hand touched sth, then my right hand has to touch the same thing or else it would bother me. Or, say I was holding my wrist, then I have to change and hold my other wrist. I know it sounds really weird, but sometimes it gets so bad that I could not sleep because of it. On really bad times, I would start twitching if I don't, esp when it happens when i'm about to sleep. It only happens sometimes though, may be once in a couple of months?
