I wouldn't worry too much about it...sure, you could have sleepwalked. But since it's not a recurring thing that you or anyone else knows of, don't jump the gun. If you were a problematic sleepwalker, I don't see going to the psych hospital as the first place one would turn. Anyway I'm sorry this is disturbing you.

I do weird things in my sleep, like talk. Boyfriends have told me, lol.
