Revolutionary? How about sad?
As an "old guy" who was doing this stuff long before the advent of social media, let me assure you that the idea of entering NREM consciously is far more classical than the now popular (and essentially incorrect) "classical view that you just lie still until SP hits."
The mechanics of WILD have been around for a very long time, probably as long as humanity has enjoyed sentience. What Sivason describes (correctly and quite well, BTW) is by no means revolutionary. Sleep yogis, for instance, have been navigating
delta sleep (NREM) for centuries. That this age-old concept and activity is considered novel or revolutionary on forums like this is telling, and by any measures quite sad. That SP and the rest of the
noise is considered important and integral to WILD by pretty much everyone is sadder still, and a real roadblock to the popular development of lucid dreaming.
