I could take care of the baby while my girlfriend was sleeping at night and I could go out or work on my hobbies all night (with 27m naps) without any problem. It was like I was a liberating experience, I watched the whole of society shutdown at night, but I was awake every day all by myself, it was very odd. I also realized I didn't really need a house if I could sleep anywhere, except in winter - but I started thinking I could just sleep 30m here and there (in trains, at work, in the park on a bench) perhaps with electric blankets. A real nomad lifestyle. I also noticed that I had to force myself being productive at night as my executive function wasn't quite there - it was like my mind was used to doing nothing consciously at night, an unconscious part didn't really see a point in being awake and doing things at night - so I mostly just was sitting there, contemplating or meditating. When I made a todo list it was better.
As I also had to organize naps outside and at friends and family places it caused some tension and conflicts (I can tell some really wild stories) - and eventually, also because I didn't want to risk potential long term issues I went to 2 naps and eventually 1 nap each day.
Regarding 35 minutes, you risk entering deep sleep with 35m, at least I did when I went over 30m a nap. Or did you mean 25 minutes?
