ELI5: How does my brain know to wake me up seconds before something happens?
I've had this happen several times, and I can't figure out how it works.
I'll be completely asleep, then suddenly wake up just seconds before my alarm goes off, someone knocks on the door, or my phone rings.
The alarm makes some sense if my body has gotten used to a schedule. But what about unexpected things, like a phone call or someone showing up at the door?
Is my brain somehow picking up on things while I'm asleep that I'm not consciously aware of? Or is this just an incredibly weird coincidence that feels more mysterious than it actually is?
