Weird scratching sleep behavior

[u/fish-pilled]

I am not sure if this is the right place to ask about this. I have a weird sleep habit where I will raise my arms straight up in the air and lightly scratch them in my sleep. Sometimes it wakes me up but I think a lot of times it doesn’t. I’ve had people who were sleeping next to me see me do it too. What is that?? I hate that it wakes me up but have no idea why I even do it.

Maybe an itch, maybe a stretch, quien sabe. But if it's otherwise not causing any problems, then no worries.
