I'll just going to continue on the same theme until I figure out something else.
Have you experienced some sleepwalking or sleeptalking, from yourself or someone else?
Once after I fell asleep in my bed I woke up in a couch, in the livingroom. That's all I guess, but I've heard a lot of people talk in their sleep.
I quote:
"You can give it to me, because I know who it belongs to"
"ARGH SUCH BAD MUSIC!!!"
*Slurping* "mmm, cake..."
