Lol, I used to have complete conversations with my son. He not only talked, he sleep walked as well. Although he's grown out of the sleep walking, his girlfriends tell me he forbids them from making him tell secrets in his sleep. Poor boy, so unfair.
I've been told I talk in my sleep, but just mutterings, nothing particularly comprehensible.
I've heard of sleepwalkers and sleep talkers. You're the only one I've heard of who has a sleep stalker.
MY WIFE and I enjoy separate sleeping quarters. We can always get together for other things, but sleeping apart is a good thing for several reasons. I snore like an asthmatic lion. She likes to fall asleep with the TV on. I smoke, she doesn't. But, germane to your post, once or twice I've woken myself up via the expedient of punching the wall during a fight that started in a dream. Yup.
