I have been waking up early since past 3 days and getting ~6hrs sleep on average. All 3 days, my brain’s power has last longer and feels like it got “overclocked”. I am able to take in lots of information, have more energy to talk to people(almost makes me think I’m might not be introverted) etc. I feel like a different person all together.

What is happening? I have no issues sleeping, I just had to wake up early and sleep late due to stuff.

    You might be waking up in a more ideal spot in your REM cycle. For me if I get 6 ½ hours I feel great but I feel like shit if I get a full 8. But if I sleep 9 I feel pretty good again. If you wake up and get interrupted during REM you’ll feel a lot more groggy and like shit for most of the day in my experience.

      I have tried this REM cycle theory for me. It doesn’t seem to matter for me. I have tried waking up at 7h30m for few days, I felt very groggy to wake up especially in this cold weather. But somehow waking up at 6hrs, almost as if I haven’t slept at all. My takeaway was that the longer I slept, the stronger sleep I had and the harder it was to wake up whether or not it was at end of the cycle or middle.
