Eye Movement Desensitization and Reprocessing (EMDR) is a therapy (initially developed in the 1980s) which helps people overcome the negative effects of traumatic events. It is extremely effective and has been used to help returning vets overcome Post Traumatic Stress Disorder (PTSD).
In addition, I have found that EMDR can also be used as an effective treatment to dispel "limiting" and negative beliefs. Essentially, EMDR helps reorganize one’s thinking which then improves one’s mood and behavior. It transforms useless beliefs into positive thoughts allowing people to have a more healthy perspective. After a session or two, clients can be taught to do this for themselves when needed.
EMDR helps people let go of thinking and feelings that have held them back and kept them stuck for years. This would include core beliefs such as "I am a bad person", "I am unworthy", "everything that happened to me is my fault", and other such negative ideas which left unchanged might cause chronic pain and distress. EMDR is not hypnosis and it does not cause a person to forget the past. It functions to desensitize harmful emotional and mental beliefs which frees people to be more resourceful.
EMDR stops the negative processing that happens when a person is distressed or traumatized. EMDR works rapidly and at times even one session can turn a client around and resolve uncomfortable past thinking or events.
