So this seems like a very interesting way to wake up. I actually kind of did this in high school cause i could never wake up. 2 alarms and the 2nd was the one that was freaking load.
so in summary.
1 alarm goes off about 90min before the time u want to wake up and is very quite. only to wake u up if your light sleeping. u can go back to bed and sleep more but then a are certain u are not in R.E.M
2nd alarm goes off when u need to wake up and is a buzzer.
this will be so u don't wake up during deep sleep.
