So... can we trigger it manually? I'd love to be able to lay down and press the 'flush brain' button.

Research on NDSR, I have been using this for days I had to wake up without proper rest.

If you have 15m, search this on YT for a guided practice and test it yourself.

Kind of related, but there is a concept of polyphasic sleep - where you sleep for small increments throughout the day (like 30 minutes every 3 hours). I did it for a bit at a startup thinking we were "hacking sleep" and "getting more productive hours out of every day!" - It takes awhile to transition to it, but once there, your scheduled "sleeps" are insane, 15 minutes, feel like straight to REM. The main problem was if you missed on schedule sleep you were a zombie.

Yeah, when I was looking into the plausibility and function of polyphasic sleep, I stumbled across studies from the US Airforce. Their conclusion was similar: In a controlled enviroment, it can be spectacular and work really, really well.

However, it is very, very fragile to any kind of interruption, so they stopped looking into it.
