This has been the case for me for over 2 decades now. I suspect I may have a backwards circadian clock even. I have sleep apnea and severe fibromyalgia, so my sleep issues are many. I rarely reach REM sleep and am often very fatigued even when I have 8+ hours of sleep per day (never consecutive, ever. Never more than 4 hours of consecutive sleep).
I feel my best in the early morning hours more than 10 pm - 2 am. More like 3 am - 10 am and I feel I get the most restful sleep during the day.
Due to the severe fibromyalgia and fatigue, I sleep when my body wants to. Mostly! I often push myself to stay awake longer than my body wants because I feel like I sleep my life away. I often joke that I sleep more than my cat, but it's true. 16+ hours a day is not unusual. Again, never, ever, consecutive hours though.
There is something called sleep debt that we allegedly need to eventually "pay", or so it is said. That is the difference between the sleep you need and the sleep you actually get, which accrues over time. Though I highly doubt there are any studies of that sleep debt being decades long! I doubt I will ever pay off my sleep debt haha!
Anyhow, yes, I think you might find a lot of us find the wee hours more restful for being the most awake. I call that my "focus time". The time where I feel most present and able to focus. I also personally suspect that because this time of the day is less busy and there is less activity going on around me that is distracting, distressful, and causing my body's fight or flight mode to be the most aggravated, I find those hours the most comforting to be awake. I have a multitude of hypersensitivities (sight, sound, smell, touch) which means I am able to function best when there is little to no noise around me. I even wear industrial strength earplugs 24/7 to tone down background noise. Over time, one will discover these little life hacks that help manage symptoms and improve one's quality of life, even if only slightly.
Just my 2 cents worth of thoughts
