Stopped halfway through because the author is apparently one of those people who think "making stuff up" becomes productive if you call it "spiritual".
Yeah, this is basically mythmaking. That's fine as far as it goes, but it's a poor substitute for medicine. The author has several hallmarks of being a quack: he is described as practicing "dream medicine", makes sweeping medical/health claims despite not (as far as I can tell) having a degree in physiology or medicine, and is part of a center for "integrative medicine" headed by alternative medicine guru Andrew Weil.
The article clearly is a cultural piece about the role of sleep in our society and I don't see where the author is making stuff up . He largely seems to be making observations about the role of sleep in our performance driven society and how that might be creating problems for us and that it might be worth taking a more aesthetic perspective on the matter. Don't think there's anything blatantly wrong with that attitude
