I go to bed on a freezing cold pillow. I get up a second later then touch my pillow, which is now burning hot. I'm a bit bewilered, but not suspicious. I turn to get my extra blanket off of the floor. I put my head on my pillow again and it's as cold as ice. i go to sleep for about ten minutes and my pillow is still cold. I touch it with my left hand and it's cold. I touch it with my right hand and it's hot.

I look at my shadow against the wall. It's yellow. Then I watch TV for a minute, then look at my shadow again. This time it's blue. I blink my eye once and it's yellow. I blink again and it's blue. Then a half hour later I look back at my shadow and it's yellow with a blue outline.
