One of my favorite descriptors is "Cooler than the other side of the pillow" because I can really relate. I bet I flip my pillow to the cool side 50 times a night.
Seems I never slow down, not even when I'm asleep. I always wake to find covers everywhere and pillows (five of 'em at last count) all over creation.
And yet, I'm remarkably rested in the mornings. Maybe I should check under the mattress for a pea. Hm.
