So I have sick kids, and had a bad night last night.
The first sleep interruption was at 12:45.
So when I was just dozing off AGAIN, and heard M cry, I knew without looking that it was 3:45. But I looked anyway, and I was correct to the minute! Kind of cool, but not really. The last one was at 4:30, so that blew the pattern. But still, it's weird.
