Anyone interested in real future healing technology could try the Blu Room.
From what I've heard, there has been tremendous success with PTSD-patients as well as many other conditions.
It is not only the light, it's the geometry and the specific materials in the mirrors and more that together with the light creates the effect.
I am not afilliated, I have just talked to people who have been to blu rooms and such.
