It is a method for the treatment of psychological stress, developed by Dr. Francine Shapiro (USA) in the 1980s. The method is based on the observation that negative emotions decrease when the eyes are moved quickly and rhythmically from left to right while the affected person is thinking about the stressful event. Both sides of the brain are thereby stimulated, and emotions are processed, similar to the way everyday experiences are processed during the R.E.M. dream phases. This usually happens very fast. The brain processes the emotion and the event is stored together with the solution (reprogramming), so that the emotion is no longer triggered, and we can handle the memory in a calm, healthy manner.
