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

Studying neurobiology/neuroendocrine systems is a great way to question who really is in charge.
It’s a lot of work man. Just being human. A lot… of work…
