Ever since I was a kid, I had this thing where I would imagine stories, sort of like playing a movie in your head, while rubbing/ spazzing my hands. I used to be anti-social and shy. And recently have developed a deep dislike for oil, oily surfaces, etc. The hand behavior hasn't gone away and it seems to be triggered (I say triggered because I get this impulse/ want to do it) when I am bored or stressed (like when trying to complete my math homework). This is becoming extremely annoying as I am having trouble studying. 
Some googling makes this sound like OCD, but at the same time doesn't really fit the description. Thoughts?
