My girlfriend talks in her sleep, but in a very odd way. It sounds like English in that the word shapes sound familiar, but it's impossible to decipher what she's actually saying. It's kind of like listening through a thin wall to someone talking on the phone.
This is an improvement though. When she was younger she was much more active in her sleep. I vividly recall having her over one weekend while the rest of my family was out of town. We dozed off watching a movie, and I woke up to her running out of the room. I chased her out of the house, up the driveway and about 100 yards down the street, full sprint. She was in shoes and I wasn't. I still have a pebble embedded in my heel from that.
That's all right - I get to tell embarrassing sleep walking stories about her, and she gets to tell embarrassing drunk stories about me.
