In Sarah Kershaw's New York Times article (July 26, 2010), she describes Dr. Barry Krakow's P.T.S.D. Sleep Clinic in Albuquerque, where he encourages patients to change their horrible nightmare images into pleasant images after they wake up. While I sympathize with people who have debilitating nightmares, I have trouble with Dr. Krakow's logic. Since dreams are created by the psyche-wouldn't it be more lasting to go deeper and use the dream and other clues to find out what the psyche is screaming about? As an Observer personality type, I want to know the truth behind what's happening. I can't see how changing the nightmare's plot, though it might work temporarily, will solve the patient's underlying problem. I do agree, however, that it can relax the patient enough to start a program of real therapy. If it's P.T.S.D. from war or abuse, a deep trust in one's ability to be safe must be rebuilt. Dr. Deidre Barrett of Harvard Medical School, a psychologist specializing in dreams, supports the use of Dr. Krakow's technique "if the nightmare work is integrated with psychiatry and behavioral therapies to treat the underlying condition."
