Belly draft 

While sleeping, the cold sensation felt on one's belly, caused when pajamas or night shirt rides up during sleep, exposing the belly to a cold draft of air in comparison to the rest of the warm goodness provided by the covers. Counteracted/prevented by tucking in said pajamas or night shirt.

My pajamas became twisted in the covers and I had to retuck to get rid of the belly draft. belly pajamas sleep
