i always find that lying on my back is better for wilds and i tend to find myself naturally in this position even when i awake, tho ive fallen asleep on one of my sides. for comfort i mostly fall asleep on my right side and/or belly, but sometimes like once a wk i find myself in a radom position, 1 leg off the bed 1 leg crunched up 1 arm over my head 1 arm hangin of the bed, lol as u can imagine.
