EMDR is known for the remarkable effect moving one’s eyes back and forth rapidly can have on negative memories; the emotions become less and less disturbing. It’s most famous (and perhaps the most requested psychotherapy) for treating war-related, and sexual assault-related PTSD. However, it works for anything related to a disturbing past memory. As you might know, REM stands for Rapid Eye Movement. EMDR’s eye-movements likely uses the same brain information processing system as in REM sleep to help the brain realize that you are no longer in danger, you did get through it, you are now in 2021, and (with regard to that event) you are now safe.
