Usually very sprawled out and alot of the times diagonally across my bed. I also always just wear a tshirt to bed. Usually my wolf tshirt. I have one that glows in the dark and its so nifty to look at before I go off to dream land
Thats how I sleep. I also don't move while sleeping apparently, I always wake up in the same position I fall asleep in. I don't have a cool shirt though. I wear shorts/pajama pants and a t shirt.
Boxers, usually on my back. Actually, always on my back. I don't understand how people can sleep on their stomach, it's ridiculously uncomfortable for me.
Summer: Shirt w/ boxers, start to fall asleep but can't, wake myself up to turn the fan on, pull the blanket off then back on, usually stretched out on my stomach, and always on the cool side of the pillow...
