Trouble waking up

[AFTT47]

I roomed with someone like you during tech school in the Air Force. He used a timer and an "8" diameter fire alarm bell to wake up. Nobody else in our wing of the dorm needed an alarm clock with that thing but it barely got him up. One morning, he just lay there, propped up on one elbow staring at the thing with a look of shock on his face - like he was looking at an alien that had just teleported into our room. I went over and shut the thing off. He slowly turned at looked up at me with the same expression. It was obvious that he didn't know who I was, he was or even what either of us were. I was sure glad when he graduated and left.
