Does anyone have a scientific explanation for this:

When I HAVE to get up at a particular time I wake up and the bed is warm, snugly and fantastically comfortable.

When I DON'T HAVE to get up at a particular time I wake up ridiculously early and I might as well be in a fridge lying on a bed of nails.
