The Evolution of Dreams

You are awake in prison, suddenly attacked by a person with a royal sword in class, then you were taught to a man like Neil deGrasse Tyson in a way to prevent you suddenly being bitten by your companion. All you can think is that you are late for work. Is this familiar? Dreams are universal experiences; they can bother us at night, let us shoot upwards from sleep and tremble with our arms trembling Our dreams are so irrational Even if it is absurd, I have the question "Why does it happen?"

Some scientists associate dreams with the evolution of our thoughts. They believe that "the biological function of a dream is to simulate threat events, rehearse threat recognition and threat avoidance." People who have these dreams will be able to face the threat when they wake up. As a result, people who dream like this will survive more frequently and take over their genes. Unfortunately, this theory does not explain random, strange or simple dreams.

Finnish psychologist Antti Revonsuo believes that the dream has evolved completely from the "threat simulation". According to his threat simulation theory, physical and interpersonal threats are serious for most of human evolution and provide a reproductive advantage for surviving people. Therefore, dreams have evolved to duplicate these threats and continue to practice them. To support this theory, Revonsuo believes that modern dreams constitute more threatening events than people encounter in everyday non-dream lives, and that dreamers usually interact properly with them . This theory suggests that the purpose of dreams is to enable rehearsal of threat scenarios to strengthen personal preparation for real threats.

We only have about 20 times to realize our dreams and to awaken our dreams. Prague robe pointed out that the fact that "you can not find the singularities of our dreams while sleeping" can be selected through evolution. This is because the dream evolved into the form of a threat simulation, "because you have to trust that the simulation is real - to practice what it is all over the world while sleeping" is there.

Theory of Probabilistic Evolution This theory argues that a dream may be a simple random process evolved from sleep, but it does not have a real purpose. It believes that early animal cerebellum is not as complex as it is today. Therefore, the sleep process is relatively simple, so they can not dream. Even if the more complicated brain evolutionary dream becomes part of sleep, there is no reason just because the brain structure is becoming increasingly complex. If you are interested in learning more about this, I recommend your dream: the adventure of David K. Randall in strange sleep science. This is a wonderful recompilation and explanation of all different theories and experiments, trying to solve sleep and dream mystery.
