Laying your head the opposite direction (where your feet usually are) helps me fall asleep super fast and so comfortably too. So no, not literally hanging upside down like a bat - but close enough.
Then your cat jumps on after to loaf up next to you, then you pull a pillow up under your chin and you scroll for a bit, and then you sleep like you’re dead and it’s magical, even though you don’t like sleeping on your stomach and your feet are hanging off the side of the bed and it‘s a little bit hotter than it should be, but your body still finds sleep. Yea…yea
