I had one of those nights of shallow sleep where I was plagued with the fear of oversleeping. Even my dreams were about being late to work. So great was my dread of somehow missing the alarm, that I was only able to relax after it had woken me up at the appointed time and I had turned it off. Only then, finally free from Alarm Anticipation Syndrome (AAS), was I able to really sleep. Which I did. For an hour. And then was very late to work.
