Good kind of sleeping

There can be 2 possibility when I went to sleep so early: I am either upset, frustrated or worried about something so much that I go to sleep right away to avoid facing problems, or I am really productive during the day and was genuinely tired by all the work that I've done, thus need to get tons of sleep to recover.

I am delighted that the later seems to be the case last night. I was really picking my brain trying to figure out how to solve some problems at work without compromising quality. Then at night I was trying out steaming food, something I never done before. I also need to update and repair my iTune library so that I can start studying French. So by the time everything settled, it's 10:00 pm, and I was extremely tired.

Still, I told myself, 10:00 pm seems early to me, and I was expecting myself waking up after a quick nap and then continue practicing keyboard.

By the time I opened my eyes again, it was 7:00 am already. I didn't remember having any dream at all, meaning that I had a very good sleep.
