I had a lot of issues as a kid, the best I think, was that a magical genie lived in the wall above my bed and would try to kidnap me while I slept. To stop him I would pile all my stuffed animals on top of the covers and sleep under them so he would get them, not me. But then I couldn't sleep 'cause it was too hot under there.
