I couldn't tell you, because I don't know. I roll around in bed all over the place until I fall asleep in whatever position I'm finding comfortable enough at that moment in time. And I can wake up on my back or on my face or on the floor, so I guess it's varied.

The only thing I need is a fan aimed at me while I sleep. After one hot summer where the fan wasn't turned off, I've become accustomed to it and feel weird without it. I also hate trying to sleep when it's too hot. But that's about it.
