I would fall asleep at traffic lights (dangerous).  And during meetings at work (just plain embarassing).  I mean, that's what OLD people do.

Once, when I was a medical student, I woke up at 1:00 am.  I was so fried and exhausted that I assumed that all the clocks in the house were wrong, and I had to get up and go into the hospital (which I had to do at 7 am every day, rush hour traffic).  I got dressed, jumped in my car, started to drive to work, realized that it was pitch black and there was no traffic, plus the clock in the car also said that it was 1 am.  At which moment I realized that it probably was 1 am after all.

Between training, work, and getting a new house ready to move into I have had a few moments. The worst one was when I was wanting a snack and decided on some microwave popcorn. I took the package out of the box and put it into the microwave. I was standing there thinking that it was strange that you didn't have to take the plastic wrapper off before putting it in. You can imagine the mess and the fumes.

Three weeks into a rigorous training course in the Army with limited sleep I fell asleep walking during the final 24 mile ruck march.  The march was done in the middle of the night.  I have no idea how long I was out for but the terrain was significantly different when I finally woke up.  Thankfully I had stayed on course on the trail and finished the march within the deadline.
