Night time is quiet, no loud talking downstairs, no annoying kids yelling outside, mostly no sirens, less cars = less noise, good time to calm down and think about stuff… stuff like weird philosophical questions and questioning if reality is real, also browsing the web in silence, looking for my next [youtube video / film / tv / anime] to watch.
It’s like 6:30 AM here lolz.
Have you heard of delayed sleep phase disorder? I have a friend who describes her sleep schedule flipping like yours. I think she ended up being diagnosed with Non-24-Hour Sleep-Wake Disorder, which is rare outside of blind individuals but can happen.
I have not heard of that. I’ll have to look into it.
