In my fraternity we all slept in a single room (a cold-air dormitory). That way you could stay up studying or whatever without bothering anyone trying to sleep. As such no alarms were allowed from 6 to 9 am and there were two people who had to sleep in their rooms for wake up duty. We had a big board outside the sleeping hall and there were 2 tags for every bunk number. And there was a nail for every half hour from 6 to 9. If you wanted to be woken up but not forced up you could put your bunk number's black tag on a certain time (perhaps 6:30) and a red tag on a different time (7:00). The guy on wakeup duty would come shake you every 5 minutes, 15 minutes prior to the tag time. At 5 minutes past, he was allowed to do anything (punching, ice water) until you got out of your bunk and put your red tag bag on its own nail. All this to say - yes. Fantastic fucking sleep. The cranked AC in the summer the open windows even in the depths of winter helped too. Deepest sleep I've ever gotten.
