Demystifying the Science of Sleep

Have you ever wondered about the stages we go through while sleeping? Our sleep cycle comprises five stages, starting with pre-sleep, where our mind settles down, followed by light sleep, deep sleep, and finally, REM sleep. During the first two stages, our brain sorts through the day’s experiences, deciding what to stash and what to trash, while the following stages are characterized by slow brain waves. Our most vivid dreams occur during the fifth stage of REM sleep, during which our mind goes through internal processes. The entire process typically lasts about 90 minutes, with the deep sleep and REM stages constituting a quarter of our total sleep. In the next sections, we’ll delve into the significance of our dreams and their impact.

The Science of REM Dreams

Dreams occur during REM, the fifth stage of sleep when the limbic system becomes more active. The anterior cingulate gyrus, a vital part of the limbic system, is linked to our self-awareness and free will. Our emotions and past memories are connected during REM, making new memories as we sleep. Our prefrontal cortex makes logical reasoning, causing dreams to be utterly bizarre during REM. Due to our paralysis during REM, acting out our dreams is prevented, and we don’t harm ourselves. Dreaming is strongly connected to our survival, and its importance will be further explored.

The Evolutionary Purpose of Dreams

Beyond providing emotional insights, dreams also serve an essential role in humanity’s evolution. The ability to practice skills and survival techniques during dreams has allowed humans to adapt and survive for millennia. The symbolism of the recurring dream of being chased holds that every person, regardless of origin, shares the same fears and reactions. While other animals also practice skills in their dreams, they may not recognize the difference between dream and reality, making them vulnerable. As children, the distinction between dream and reality is taught to humans by their parents, who reassure them when they wake up from nightmares. This crucial ability to differentiate between the two worlds has allowed humans to harness the full benefits of dreams and thrive as a species.

The Power of Sleep

Contrary to popular belief, sleep is not a time for the brain to rest. Our brain uses this time to consolidate and store new information in our memory bank. Research shows that during Rapid Eye Movement (REM) sleep, the brain is as active as when we are awake, and this is when we have the most vivid dreams. Dreams help us solve real-world problems by using metaphors. Evidence suggests that they play a fundamental role in both our intellectual and emotional growth. For instance, dreams help us to memorize things, draw connections and solve problems subconsciously. So, if you want to be better at learning and emotional regulation, let your brain dream.
