Sometimes.
I love when I wake up, and it's like I didn't move all night, the bed is still made. (Score!)
Less cool is when I have stressful dreams and everything is all over the place, pillows on the ground, elastic-sheet-thingy ripped off the mattress and twisted all around me.
And one time I woke up INSIDE my duvet cover.. wtf. No wonder I was cold all night.
