<human>: This actually happened over the weekend, but here goes. I wake up very early on Saturday morning in the bathroom in the middle of taking a dump. I'm not much of a morning person, so I just figured I was too groggy to recall getting out of bed and going to the washroom. I go back upstairs to the bedroom, and there's my girlfriend looking quite confused and upset.

GF: "Are you going to clean that up?"

Me: "Wha?"

GF: "The pee all over the air conditioner and the window!"

I haven't sleepwalked since I was a little kid, I'm 28 now and it's never been an issue... until now. I guess I got out of bed, started yanking on the front of our window AC unit in the bedroom, opened the filter flap and just started peeing in it. If your AC unit has ever gotten water in the fan, you know the sound it makes. It was making that sound... but from piss. The blowback from the fan caused my pee to spray all over the window, all over the floor, and it was this point when I noticed I had a pretty good sprinkling of pee on myself as well. 

I guess while I was doing all of this, my gf was yelling at me, and I just kept mumbling generic guy responses like "Yeah", "I will", and "I know", then just turned around and left the room. Once she realized that I had been sleepwalking and had no idea what I was doing (and after I cleaned up all the pee and showered) we had a good laugh about it and she wasn't mad at all. That is how I know she's a keeper.

Also, I should mention I do remember having one of those "I really have to pee" dreams at some point that night, and the window in question overlooks a busy park...

Provide a brief overview of the text.
<bot>: Sleepwalked for the first time in over 20 years, peed into a window AC unit in front of my horrified girlfried.
