Reverse-learning hypothesis - Why do we dream ?

In the eighties, there was yet another theory introduced. Francis Crick, had the Reverse-learning hypothesis developed. This theory assumes that memories are stacked, because there is not enough room in the skull to each other. The memories are then partially the same neurons in use. If the overlap is too large, there is an overload, and that leads to fantasies, obsessions, and sometimes hallucinations. That does not happen when someone is awake, but if someone dreams, for then all the muscles are paralyzed. During REM sleep by the PBL impulses unnecessary, and overburdened memories discarded, and then processed in a dream.
