Hello everyone. First time I post here.
I'm not sure this is the right place to ask, but there is something strange that's been happening to me when I sleep lately.
Usually, I always fall asleep on my side. Curled up in a little ball. Sometimes with one hand under the pillow, sometimes not.
Normally when I wake up, for as far as I can remember, I wake up on either side.

However, lately I've noticed I often wake up half on my back, with my left arm raised above my head. It's in the same position as if I was scratching my neck or something but I'm not under my head.
I simply have my arm bent, hand near the side of my head and elbow pointing up. I wake up like that naturally in the morning.

It doesn't really bother me, but I've been waking up in this position a lot lately. Almost every night and I never slept like that in the past. It's really only started recently.

Anyone knows what this could mean? Is it something to worry about?
Thanks!
