wow i had absolutely also no idea that this was a thing. But this also comes from a fairly good sleeper. Recently I had a bad sleep cycle for a while (nightshifts mess up your schedule every now and then) and I tried this app that telling you breathing exercizes. Honestly, I didnt like it because while falling half asleep you are still trying to listen what they are saying.
But yeah I get why there is a whole generation that doesnt sleep. Phones, email bliebs distract us untill the last second that we close our eyes, and that is where that all comes from! (I think)
