I don't think I've had any keyboard related dreams....lately......
Of course it's possible I post in my sleep.
I recently learned I sleepwalk (Somehow managed to sleepwalk in a friends basement, accidentally woke one friend up, held a conversation, then walked up a flight of stairs, went to the bathroom, washed my hands, and went back to bed, woke up wondering why I didn't have to go to the bathroom anymore. Weird.) So I wouldn't doubt that I come here and post in the wee hours of the morning
