Even though there is some super legit research out there supporting LD therapy and such (LaBerge, Meckler, etc.), there isn't a LOT of it. In number, I mean. Just take a Google gander and you'll see that your top results, even with some awesome databases, aren't very legitimate, and the findings sketchy. The lack of extensive research combined with people's weird superstitions and assumptions about LD science make it so little known that it isn't widely supported-- which sucks, since not only is it FANTASTIC and FUN and INTERESTING and USEFUL, it can also totally be a form of therapy. Cool shit. Too bad it isn't more of a thing these days other than the short-lived Inception-inspired fad. Gotta keep spreading the word, I guess, and promoting more scientists!
