It is good for us that the neurotransmitters kick in or else God know what we would be doing. Your eyes alone also have a big part in the dreams images-Dream images are thought to originate in the centre Of the cerebral cortex, the brains grey matter and the minds hub for memory, awareness, cons( senses, and thought. While the part of your visual cortex that takes in new images sleeps right along with , the part that interprets images stays wide awake. So, basically, your brain gets down to business, Eng to makes sense of all the bits of memory and imagination. The human brain is a mysterious little ball of gray matter. After all these y , researchers are still baffled by many aspects of how and why it operates like it does. Scientists have b performing sleep and dream studies for decades now, and we still arent 100 percent sure about the if on of sleep , or exactly how and why we dream. There are several theories as to why we dream. One is this names work hand in hand with sleep to help the brain sort through everything it collects during the waking ours. Your brain is met with hundreds of thousands, if not millions of inputs each day. Some are mini sorry details like the color Of a passing car, while others are far more complex, like the big presentation e putting together for your job.

Studies indicate that as were learning new things in our waking hours, dreams increase w we sleep. Participants in a dream study who were taking a language course showed more dream act Han those who were not. Another theory is that dreams typically reflect our emotions. During the d our brains are working hard to make connections to achieve certain functions. When posed with a tough h problem, your brain is incredibly focused on that one thing.

The same goes for simple task e hitting a nail with a hammer. Have you ever lost focus and smashed your finger because your mind was else where?

Its during sleep that the emotions of the day battle it out in our dream cycle. If something is weighing heavily on your mind during the day, chances are you might dream about it either specifically, or through obvious imagery. For instance, if youre worried about losing your job to company downsizing, you may dream youre a shrunken person living in a woo RL of giants, or youre wandering aimlessly through a great desert abyss. Theres also a theory, define tell the least intriguing of the bunch, that dreams dont really serve any function at all, that theyre just a poi nettles byproduct of the brain firing while we slumber. We know that the rear portion of our brain gets pretty y active during ERM sleep, when most dreaming occurs. Some think that its just the brain winding down for the night and that dreams are random and meaningless firings of the brain that we dont have when we re awake. The truth is, as long as the brain remains such a mystery, we probably wont be able to pinpoint w tit absolute certainty exactly why we dream.
