How is it possible to WILD if there are at first 4 hours of NREM sleep? Isn’t it only possible to do it after NREM is over?
Sounds a lot like what 12341234 was asking in this topic:
In that thread, I put forth my own guesses, too, but I might have to change them after getting that proper quantity of FOUR HOURS of NREM? 
That’s a lot to forget as soon as it happens…
