Have you ever wondered why you sleep on a certain side of the bed? I’ve read a few different discussions on this. Some having to do with power positions, some with familiarity, some with where your parents kept you as a baby.
What I’ve found most interesting is returning to a bed after awhile. Maybe it’s your high school bed when you’re home visiting parents, or you lived with someone for awhile and are back on your own. What I’ve noticed is that you crave the same position. Even if you slept on the opposite side for years.
I tend to switch sides when I’m on my own, and usually end up towards the middle of the bed. I’ve always wondered if we have some type of sleep muscle memory. Maybe our bodies remember every night of sleep, and the environment, even though our conscious brain doesn’t.
