For me, sleep before midnight is the most important factor. If I need my brain working well the next day, all I need to do is go to bed by 10PM. Even if I wake at 5:30, it will be fine.

BTW, nights were I have dream recall afterwards, are the best. Anyone else have made the same observation?

Same, and most of the times it’s when I sleep longer. Perhaps because there’s a lot of REM sleep towards the end of the night (as my Garmin watch tells me) and/or because I’m kind of half awake at that time. So maybe dream recall indicates I slept a whole night

Building on this, I’ve observed nightmares (I.e., particularly intense, terrifying, or otherwise challenging dreams) guarantee a good next day.

Interesting. I've found that nightmares are strongly influenced by what I've eaten. Cabbage gives me nightmares almost certainly, for instance. Generally for me dream content seems heavily related to sensations in general : sounds, smells, bowel movements, cold, heat, weird limb positions...

same. but, mostly no recall lately. as I go to bed at 2:00 and sleep 6 hours max

Ouch that’s rough. A few nights like that and life just feels hard for me. Gloomy outlook, bad memory etc
