"We always appreciate feedback from our users and we appreciate you being a RadarScope customer. He says that although the theory is gaining acceptance among researchers, "There is no evidence of that.This is the official reply from the Radarscope app developers for your information: Jerome Siegel, a researcher at the Center for Sleep Research of the Department of Veterans Affairs, believes evidence remains too thin to support the theory that dreaming is therapeutic. "When we wake up from something like that, people usually feel the trauma all over again," she said. Rather than associating random memories and trying to make sense of them, some nightmares can often too closely resemble the episodic memory of the trauma, itself. In fact, nightmares can do more harm than good, particularly if they wake a person during the night. But, she adds, not all dreams are therapeutic. "It's as if the mechanisms that prevent episodic memory from happening during sleep are broken down," said Stickgold.īarbara Rothbaum, a psychologist and director of the Trauma and Anxiety Recovery Program at Emory University School of Medicine, agrees dreaming can provide patients with a method of working through issues. Three-quarters of the patients reported seeing the geometric shapes associated with the game in their dreams, even though they had no memory of the game itself. But then researchers woke the patients from their sleep following hours of game playing and asked them about their dreams. Even after playing the game for seven hours at a time for weeks, the patients had no memory of playing the game. Stickgold had amnesia patients play the computer game Tetris, which involves manipulating falling shapes to fit into a patterned edge at the bottom of a computer screen. Stickgold has also worked extensively with amnesia patients who have damage to their hippocampus where the mind records what's known as episodic memory - experiences recorded in sequence and context. Studies in rats, for example, have shown that the neocortex region of the rats' brains are most active during sleep, while during the day the hippocampus region shows more activity. Some animal studies have supported the theory, which is shared by a growing number of brain researchers. "The job of making all these connections and weighing the associations and sorting out what makes sense is a hard one and it seems to be something we do best in our sleep." "As a culture, we know you can pretty reliably go to sleep with a problem on your mind and reach an answer by the next morning," he said. Here, information isn't recorded, but compared and meshed with other memories and processed in a way that's difficult during waking hours. And some scientists and psychologists claim that's exactly what's needed.ĭreams, says Robert Stickgold, a sleep researcher at Harvard Medical School, allow the mind time to switch gears from one part of the brain, the hippocampus, to another, the neocortex. 11, are dreaming about the events in one way or another. Many Americans, seared by the attacks of Sept. And there's the New York City firefighter who, in his dreams, keeps returning to the World Trade Center site just before the buildings collapse and running to save his father on the eleventh floor. There's the air traffic controller at Dulles International Airport who, in her sleep, keeps seeing the image of the hijacked plane on her radarscope and then wipes it away with her hand. 5, 2001 - If we haven't had the dreams, ourselves, we've at least heard about others'.
