I sleep in all of the above ways, as well as a few that aren't mentioned, like curled up in a ball, bent into an L shape, and standing on my head. It can take hours to find each specific night's comfortable position, and a end up having to contort myself into some very strange positions to sleep well. The pillow arrangement is also important. Sometimes the pillows go under my head, sometimes they're next to it, and sometimes they're covering it. Sometimes I use my pillows to cover my feet. It's always different. Is this normal?
