    How does your brain know when the end of your sleep is?

      Is your brain a separate entity? You literally decide when to wake to with alarm. Or if you don’t set a time, it wakes you after x hours, after it’s backloaded all the REM.

      If sleep deprivation gets too bad, it’ll completely knock you out to get as much REM in as it feels you need to function, alarm or no alarm.

        So it just anticipates when my alarm is about to go off?

            That keeps me from going back to sleep all the time. Like oh I have another hour? Then it’s 30 minutes to fall back asleep and then that’s only 30 minutes so better I just get up. I get tired by the end of the day a lot lol

      Weird polyphasic sleep schedules take weeks to start working, so probably from patterns. Although if what op comment is true something else is happening too
