Do you sleep in the same spot every night? I'm chuckling at the idea of you getting tired and just picking a random bit of floor within your house to lie down.
You made me laugh, thanks! I do have three blankets (on which I sleep) that I store in my closet during the day. Most of the time I put my bed on the same spot, but sometimes I move it slightly (towards the windows on hot days, etc.), although not that much.
