When I was really little and trying to fall asleep, I would lay with my ear to the pillow, listening to my heartbeat. I used to think that there was a giant marching through my ear (don't ask me how a giant got in my ear) and if I rolled over to the other side, he would escape and eat me. I didn't get much sleep during that period.
