Why do we dream? – Amy Adkins


In the third millenium BCE, Mesopotamian kings recorded and
interpreted their dreams on wax tablets. A thousand years later, Ancient Egyptians wrote a dream book listing over a hundred common dreams
and their meanings. And in the years since, we haven’t paused in our quest
to understand why we dream. So, after a great deal
of scientific research, technological advancement, and persistence, we still don’t have any definite answers,
but we have some interesting theories. We dream to fulfill our wishes. In the early 1900s, Sigmund Freud proposed that while all
of our dreams, including our nightmares, are a collection of images
from our daily conscious lives, they also have symbolic meanings, which relate to the fulfillment
of our subconscious wishes. Freud theorized that everything
we remember when we wake up from a dream is a symbolic representation of our unconscious primitive thoughts,
urges, and desires. Freud believed that by analyzing
those remembered elements, the unconscious content would be revealed
to our conscious mind, and psychological issues stemming
from its repression could be addressed and resolved. We dream to remember. To increase performance
on certain mental tasks, sleep is good, but dreaming while sleeping is better. In 2010, researchers found that subjects were much better
at getting through a complex 3-D maze if they had napped and dreamed
of the maze prior to their second attempt. In fact, they were up to
ten times better at it than those who only thought of the maze
while awake between attempts, and those who napped but did not dream
about the maze. Researchers theorize that certain
memory processes can happen only when we are asleep, and our dreams are a signal
that these processes are taking place. We dream to forget. There are about 10,000 trillion
neural connections within the architecture of your brain. They are created by everything you think
and everything you do. A 1983 neurobiological theory of dreaming,
called reverse learning, holds that while sleeping,
and mainly during REM sleep cycles, your neocortex reviews
these neural connections and dumps the unnecessary ones. Without this unlearning process, which results in your dreams, your brain could be overrun
by useless connections and parasitic thoughts could disrupt
the necessary thinking you need to do while you’re awake. We dream to keep our brains working. The continual activation theory proposes
that your dreams result from your brain’s need to constantly
consolidate and create long-term memories in order to function properly. So when external input falls
below a certain level, like when you’re asleep, your brain automatically triggers the generation of data
from its memory storages, which appear to you in the form of
the thoughts and feelings you experience in your dreams. In other words, your dreams might be
a random screen saver your brain turns on so it doesn’t completely shut down. We dream to rehearse. Dreams involving dangerous and threatening
situations are very common, and the primitive instinct
rehearsal theory holds that the content of a dream
is significant to its purpose. Whether it’s an anxiety-filled night of
being chased through the woods by a bear or fighting off a ninja in a dark alley, these dreams allow you to practice
your fight or flight instincts and keep them sharp and dependable
in case you’ll need them in real life. But it doesn’t always have
to be unpleasant. For instance, dreams
about your attractive neighbor could actually give your reproductive
instinct some practice, too. We dream to heal. Stress neurotransmitters in the brain
are much less active during the REM stage of sleep, even during dreams
of traumatic experiences, leading some researchers to theorize that one purpose of dreaming is to take
the edge off painful experiences to allow for psychological healing. Reviewing traumatic events
in your dreams with less mental stress may grant you a clearer perspective and enhanced ability to process them
in psychologically healthy ways. People with certain mood disorders
and PTSD often have difficulty sleeping, leading some scientists to believe
that lack of dreaming may be a contributing factor
to their illnesses. We dream to solve problems. Unconstrained by reality
and the rules of conventional logic, in your dreams, your mind can create
limitless scenarios to help you grasp problems and formulate solutions
that you may not consider while awake. John Steinbeck called it
the committee of sleep, and research has demonstrated the effectiveness of dreaming
on problem solving. It’s also how renowned chemist
August Kekule discovered the structure
of the benzene molecule, and it’s the reason that sometimes
the best solution for a problem is to sleep on it. And those are just a few of the more
prominent theories. As technology increases our capability
for understanding the brain, it’s possible that one day we will discover
the definitive reason for them. But until that time arrives,
we’ll just have to keep on dreaming.

    Man, I've never really trained any fighting skills, but I was always playing that I'm fighting since I was a kid, and watching movies of it. Then, in many of my dreams, I actually needs to fight and that doesn't only make me remember some movements but also learn new ones. And then come one day that I really had to fight in real life after a argue, and it was against one man that was training for years but, for my surprise, I beat him without even getting hurt, and you know how? By using my skills that I got from training at my dreams 🙂

    Muslims have specific interpretations for their dreams which indicates future and it’s 100% true . I always interpreted it and turned out always correct

  • 獣TIGLE says:

    I learned some stuff from dreaming, that I never knew in my life. In my theory our brains observed anything that we see, hear and feel. Our brain just don’t process every information when we are wake. Because In that moment our brain is under our control. When we sleep we can’t control (I meant think or do what ever we want). But when we are sleep our brain get rest. And that moment our brain starts making images, sound and feeling. From what our brain learned from our environment. Simply in my Theory, Our brain has also had will of its own. The will we keep in our control when we are awake. If you follow my theory, You will realize our brain is a living creature that’s inside us. And we are able to control it. We are not exactly our brain. Our brain is different from us. The mutual relationship between our body and brain keeps us as a one living being. I know it sounds crazy. But that’s my theory.

When i was a kid, i've dream about my mom teaching me to play a violin. And 2 days after that, my mom start giving me a violin lesson. I always had this dream in the weekend or so.

    Does anyone have that kind of dream?
