My theory is that your feet could be cold most of the day and when you lay down, the blood circulation to your feet increases, raising the temperature of your feet. The nerves in your feet are used to that cold feeling and interpret the temperature change as "hot".
You can explore this phenomenon by filling two bowls with water, make sure that one is reasonably hot water and the other is cold water. Put each hand in a corresponding bowl of water until each of your hands are feeling very warm or very cool (respectively). Now pour both bowls of water into the same bowl and stick your hands in it. Feel the difference? One hand (the one that was in the cold water) feels that the water is hot. The other (the one that was in hot water) feel that the water is cold.
I'm not aware of your medical history, nor am I an Md. But, it Sounds like an issue with your nerve endings...ie. Neuropathy. If it is neuropathy, you'll need to see your MD for treatment (medication).
