Have you heard of Se-REM? (Self effective - Rapid Eye Movement). Many people don't know that REM brain activity dramatically improves the processing of traumatic emotion. It creates peace and empowers the listener. Se-REM is an advanced version of EMDR therapy. It is more powerful because it combines elements of 6 different therapies, EMDR, hypnosis, mindfulness, Gestalt child within work, music therapy, and Awe therapy,(connecting profoundly with nature).

It has helped thousands of people overcome PTSD, and anxiety. But it is also helpful in a great many situations, loss of any kind, grief, and even marital counseling. It's mission statement is "Trauma relief at as close to free as possible". This not-for-profit program downloads to a smart phone or computer and can be used in an office or at home. Read about it, hear samples, and download at: Se-REM.com. Once you own the program, you are encouraged to give it away to others who will benefit.
