When I was in Middle School, my cousin from Korea (Korea and Asia in general have the freakiest ghost stories >_>) told me that whenever my hands or feet fall off the edge of the bed, it was because ghosts under the bed were trying to pull me down.

Ever since then, I've slept in a ball in the middle of my bed. I'm serious, I never let my arms or legs go off the side of my bed when I sleep.

And I don't even believe in ghosts.
