I think a good EMDR therapist could explain it best, but the bit that I read which made sense to me, is it synchs up the 2 sides of our brain. That's something that makes sense to me, the stuff that I learned about the brain having logical and creative sides could mean we lost some of the ability to process things? And when I read how rapid eye movement, is simulating REM sleep, it makes more sense to me. I know I've seemed to have lost the ability to dream, and that sleep deprivation probably the cause.
I'm thinking about this for myself, but it just seems logical that if I'm not slept well for decades, don't dream (my perception) and been diagnosed with ptsd from the trauma...? Well, with all the symptoms I have, my research showing those symptoms calm, I really want that, badly! So, I'm very motivated, but money insecure. I've been looking for a trainee to be their subject. It's not going well.
