The Psychological Theories Behind Why You Dream

Believe it or not, scientists still do not know why we dream. There are many theories as to why we dream; some think that dreaming is necessary for the brain to function, while others say that dreams serve no function at all. Either way, dreams are here to stay.

Dreams are involuntary images, ideas, emotions and sensations that occur in the mind, usually during certain stages of sleep. Dreams usually occur during REM (Rapid Eye Movement) sleep, where the brain activity is higher than normal. Dreams can still occur during other stages of sleep, but are less likely, and the dreams are not as vivid or memorable. One theory says that dreams are just caused by REM sleep, and serves no natural purpose—and that people can go about their lives without ever needing to remember or think about their dreams. Another theory involves the idea where the forebrain is reacting with random activity from the
of the brainstem, and that the mind is simply sorting out and piecing together random information in the brain. A further theory suggests that when you dream, you are in a different biochemical state and that the brain—while dreaming—is working out different solutions to different problems you have been thinking about during your time awake, and that dreams create new ideas to these problems. In another theory, the idea that  dreams have evolved for the pure purpose of simulating threatening scenarios, to arm the dreamer against possible threats or problems that they may encounter at some other stage in their life. And lastly,
another theory argues that dreams are essential for humans to survive, and that people dream four main themes: danger, social standing, health, and sexuality. According to the theory, we dream about danger and health to arm us against these things in real life, and dream about social status and sexuality to encourage us to feel good about ourselves. At this point in time, there is no real proof as to why we dream, so in the meantime, it's up to you to decide.
