Maybe the reason there's not enough hours in the days is because we came from a world where the days were longer?

No. We come from a world, Earth, where days were actually shorter.

The gravitational pull of the moon on the tides causes the Earth to slowly lose angular momentum (and the moon to drift away).

The days are actually getting longer every passing second.

your brain is processing signals slower
less sensations it detects faster time feels like it's moving

got sick last year, my senses numbed out. 6 hours was like 5 minutes. truly scary shit

the better your senses work, the better throughput of your brain to process them all consciously, the slower time will pass

enlightenment is depicted as slowing down time to a crawl so you go faster than the world, and exercises for reaching it work on exercising neurons that detect bodily sensations at all times
some drugs can do the same, like weed or psychedelics
