It's called EMDR: https://en.wikipedia.org/wiki/Eye_movement_desensitization_and_reprocessing https://en.wikipedia.org/wiki/Eye_movement_desensitization_a...

You can practice it right now on YouTube: https://www.youtube.com/watch?v=OlfQIRJEsYk https://www.youtube.com/watch?v=OlfQIRJEsYk The idea is to think of something emotional that you may be struggling with and keep it in your mind while following the images on the screen. Whether or not the eye movement actually triggers the brain to reconfigure itself, or whether it's simply keeping the emotion "in focus" that brings the changes remains TBD, I think.
