When you sleep, and everything is silent you can sometimes hear your blood pumping round you, as your head is on the pillow. I had this hate of werewolves and used to believe that as the blood was pumping faster-the werewolve (that was trying to kill me) was gaining on me, and it was going to eat me. To prevent this I had to breathe heavily so that I couldn't hear the blood pumping
