If considering you share a bed with a partner then the choice of which side of the bed to sleep on surely depends whether you are right handed, left handed or ambidextrous?
For some reason i always sleep on the side furthest from the window, and nearest to the door.... have no idea why, its not like i ever sleep anywhere that i need to make a quick exit from!!
it's weird, when I'm at my boyfriends, I sleep on one side-next to the wall, and at mine I sleep on the other side, which is the open side... and the other morning I woke up and was on his side... and I have no idea how it happened..!! weird! Lou xx
