OK so for me I would usually go to bed between 10pm or 11pm. On odd nights would go to bed at 11:30pm. This year I've been going to bed around 12am - 1am. I've been doing it about 2 months now, and I think I'm getting used to it. I don't know why but normally I would feel like dying each morning, but it's not too bad anymore.

At first I was so exhausted that I wouldn't remember any dreams in the morning, but now that I am getting used to it, and I am remembering dreams like before.

first of all, does the body get used to getting less hours of sleep and adjust accordingly, and if so, how?

Also has this ever happened to you?
