ooorgh. I'm having another "could sleep through the battle of Kursk going on in the next room and then three hours later I'm VERY AWAKE" night.
@Leucrotta And surprisingly, well, cyclic. When we were in college I tried paying attention to the timing and it always ran on hour-and-a-half cycles. It was like we were on a timer.
@Leucrotta Oh, mood!
Sleep cycles are kinda weird.
