Half an hour into work, I was taking thirty-second naps every thirty seconds. That was fine when my mind was just blanking out and the new phone call would wake me up and I would talk or cancel it if it was an answering machine, but when I started dreaming...
I woke up to find that I'd just told a guy that the fleas on the cat in his doghouse did not count for people between the ages of eleven and seventeen living in his household.
It was at this point that I decided I'd better go find a supervisor and get sent home sick, but it took me half an hour more to wake up enough to get out of my seat and find someone.
When I got home, I hallucinated out loud for a little while before finally crashing on the couch and sleeping. Dude tells me that I woke up at least twice while sleeping, though he was trying to keep me from waking up, but since I don't remember waking up in the middle of it all, I guess I must have been very very out of it all.
