I fell into this routine for a few weeks during my OS course in college. Didn't have much social life as I was working on my OS for about 10 hours each day (or catching up in my other classes...), so it was easy. I went to bed when I felt tired, usually around 8 or 9 PM, woke up for an hour or two around 1 or 2 AM, then fell back asleep until morning, 7 or 8 AM. During the middle hour, I felt the intense relaxation and started writing poetry/drawing during the period. I'd often just stare out the window, enjoying the feelings of tranquility. I even wrote some code once that I'd been struggling with before I fell asleep. The dream recall is intense -- you can remember every detail, rather than fighting as it fades away -- so I also started keeping a brief dream journal. I'd love to do it again, but it's not feasible given the rhythms of NYC. If I ever move someplace quieter and decide to simplify my life, I'd eagerly return to the segmented sleep schedule.
