I'm the restless one.
As a pre teen, in the same bed as my big sister, I bit her and hit and kicked her. She copped teasing over that because the bite looked like a hickey!
I got up and "showered" in my sleep. Went through the motions using my sheet as a loofa in the middle of the room.
I am known to occasionally strip the bed while DH is still in it.
I whacked him, hard, in the belly. I was sure there was a spider dangling there! I was saving him, sheesh.
Generally I have a good old chat, a walk around, and then go back to sleep.
And no, I don't remember most of it. Unless I wake up halfway through the act. Haha!
