Lucid Mike, explain your predicament to your boss, plain and simple, and I’m sure he’d let you come in later, all for the sake of a “lucid dream”. 
Matrixman, Staying up any longer than a minute or so used to be my problem…but now, I fall asleep really quick. I think I’ll try to stay up 15 or 30 min, seeing as I don’t have a boss right now, and I’ve been as tired as stated below.
To prove how tired I’ve been, the other day I set three alarms for WBTB, When I woke up and they were all going off, I turned them off and supposedly went right to bed. Unfortunetly, when I woke for the day my alarm clock had been turned upside down, my phone had been thrown across the room, and my pillow was at the other end of the bed. That was weird.
