I'm told one time in my sleep I sat up, looked down the hall, and said "You can't see it from here but it can see you.". Then laid down again and went quiet. My partner at the time was not amused
I once asked my ex husband "does it have Scweppevescence" (it was a tag line in a ginger ale commercial), and told my current husband that I had figured out the tile problem.
Oh sleep talking nonsense is the best! When I was in college my roommate wrote down what I said whe I was sleeping, it could be roughly translated like this:
"We have a crooked goat in our head that we can grab by the wall and then we can go fuck ourselves because we've had enough of it and that's it"
