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.
