Why do we dream? There are five modern theories as to why we dream. Theory #1  Evolutionary Theory:   The basic context of this theory is that our brain fires off the "fight or flight" reflex in our sleep while our body is unattached to our conscious so that in the real world, when we are awake our bodies "fight or flight reflex" reacts better. This is thought because the amygdala (fight or fight part of the brain) and the motor controls part of the brain fire off more than normal during consciousness. Theory #2  Dreams Create Wisdom   The thought behind this theory is that dreams sort through our memories to determine which ones to keep and which ones to lose. This is to decide which memories are important enough to help us to make better decisions in the future. Theory #3  Dreaming Is Like Defragmenting Your Hard Drive This theory is that dreaming is like a machine that gets used to connecting data in certain ways. Dreaming is the way of streamlining the system and keeping our minds sharp. Theory #4  Dreams Are Like Psychotherapy In dreams, we we deal with emotional content in a safe place, making connections in our subconscious that our critical and defensive brains could not make. We think of things in a less rational and defensive way, which may lead us to truths that our brains would normally suppress. Theory #5  Absence Of Theory This Theory simply says that dreams are the random firings of our unconscious brains. There is no deep meaning, Reason, or cause.
