Dreams are a very ponderous things. Simply saying, dreams are a stream of images, sounds, and

the actions of something; like a movie. But never have dreams been able to be explained. The

Greeks and Romans claimed that dreams were signs from their gods and had prophetic magic

(www.scientificamerican.com). Even though the purpose of dreams has not been discovered, a

huge movement in the study of dreams occurred at the end of the nineteenth century. In 1952,

scientists in Chicago discovered electrical readings during a certain stage of sleep. When woken

up in this stage, people almost always remember their dreams. This stage is the only stage of

sleep where we dream, and it is known as the REM stage (YouTube.com).

During the REM stage your brain acts as if it is awake, with a small difference. Chemicals, such


as norepinephrine, serotonin, and histamine, are blocked. This causes your body to become


paralyzed so that you do not act out your dreams. With this being said, it is possible to wake


suddenly not being able to move because your body has not stopped blocking chemicals from


entering your system. The REM stage is the deepest sleep stage. In this stage your heart rate and


breathing become inconsistent. REM sleep is very important, even though it only takes up about


25% of your sleep cycle. Without REM sleep, your body is tired and cannot remember things.


Your body, even though it is paralysed in this stage, relaxes. REM sleep is vital for the body,


even though the exact reason is not known. Without it not being known, it affects the theories of


why we dream. (YouTube.com)



There are many theories on why we dream. Some of them fall into the religious aspect of

things, but most are...

between emotion and symbol help the brain recognize the emotions and weave them into

our personal history.Ultimately, this hypothesis brings us back to the storytelling

component of dreams. We seem to use these bizarre images and ideas to make sense of

the day's events, to turn random neural firing into something coherent, and even to figure

out how we should feel about what's happened to us. There is no doubt that dreams play a

major role in our thought processes. The question remains, however: Are they an

evolutionary adaptation, or just an uncanny accident? (10 theories that explain why we dream)


Whether it is believed to be a distraction or an adaptation, dreams are still a mystery.

Scientists and society may ponder on the interpretations of their meanings and origins

until the end of time. Until then, we will just keep dreaming!

Dreams Essay

- Dreams Although the idea of dreams has always been a psychological one, there is a philosophical side to them. Descartes once said, "For all I know, I might be dreaming" (Bruder/Moore, Philosophy, 81). This conjecture of Descatres was one that explained the concept of dreams.

There can never be an answer to this question but it proves that there is a philosophical view of dreams. A dream is a form of mental activity that occurs during sleep....   [tags: Papers]
