Trauma is anything that happens to us that overwhelms us so much it changes our world view, how we see ourselves, and how we see others. In 1987, Viet Nam vets, still reliving their war experience even though the war was long over, were used in an experiment using EMDR (Eye Movement Desensitization and Reprocessing). After several sessions with EMDR, many of these vets found they could finally put the war to rest, develop trusting relationships again, and return to the world in a functioning way.
*Bilateral stimulation is anything that activates one side of the body/brain with the other, i.e, the eyes moving back and forth like what happens during REM sleep. This can also be achieved by using a Thera-tapper, a device that alternately vibrates your right and left hands.
