I do and felt so cold, tired and hurting a lot when I woke up. How I did this I have no idea. When I went to bed last night I had a regular sheet on top of me, then a down comforter, then 2 wool blankets then another down comforter. I woke up with regular sheet on top of me then a down comforter then the other down comforter on top of the second down comforter was a wool blanket at my feet followed by the other wool blanket next to my bed. How did my 2 wool blankets go from in between the down comforters to one on the floor next to my bed and the other above both down comforters and at my feet? Anyone else exercise while sleeping?
