  1. Interesting. Makes sense. The non-(hard)-scientific approach (Freud) claims that dreams “re-organize” the day’s events. Or long-standing memories, or traumas. In other words Dreams serve as a healer, shuffler. A common torture technique used by the Eastern block in the cold war was to let prisoners sleep but detecting REM, indicative of dreams, wake them up before they could dream. All subjects confessed to anything after a few days. (Don’t let the Orange man find out)
