BODY
I.I’m sure most, if not all of you have experienced what it is like to dream. But what exactly is a dream?

To define a dream, we first must define sleep. Sleep is the most important aspect of dreaming, without sleep you cannot dream.

1. There are two specific parts of sleeping. In an an Article called Dreaming by Today’s Dreaming they talk about the two types of sleep. There is Synchronized or Non-Rapid Eye Movement sleep where there are little to no reports of dreaming. The second type of sleep is Desynchronized, dreaming or rapid eye movement sleep. This type of sleep causes your eyes to move rapidly, your autonomic nervous system to be activated, and for you to dream. The average person has five cycles of rapid eye movement sleep and dreams are had in intervals of about 90 minutes. What is interesting, is that a dream period usually lasts from 5 to 20 minutes (Dreaming).

2. In an article called Biology of Sleep by Marvin Rosen, he shows a study by Nathaniel Kleitman and Eugene Aserinksky at Stanford University in 1953 that proves that subjects are sleeping while in Rapid Eye movement sleep. They saw that after about an hour of sleep, the subjects eyes would move rapidly back and forth, and the subjects would awaken and tell them they were dreaming. Hence this stage of sleep being called rapid eye movement sleep. (Biology of Sleep)

B. Coming from a Biology major I always find it interesting to learn what happens when we are awake and what parts of our brains are active, but it is even more interesting to see what is active when we are asleep and dreaming.

1. In Rosen’s article Biology of sleep he recognizes the parts of the brain that are used during Rapid eye movement sleep. He states, “..what we see when we dream are modifications of what we see when we are awake. Which suggests that the parts of your brain that are active when you’re awake, are also active when you are dreaming. It has been shown in tests that the visual cortex, the part of the brain responsible for vision, is firing during sleep. Presumably, this is why we have visual imagery in dreams. The only thing that seems to be different is that without being awake there is no perception of time which is why some dreams can seem to last hours, when in reality they are only lasting a few seconds.” (Biology of Sleep).

a. In Rosen’s article he shows that not only is the auditory cortex used but the limbic system is also used. The limbic system lies at the innermost edge of the cerebral hemispheres. Part of the limbic system is the hippocampus, which is the key for storing memories. Without the hippocampus short term...

This is a short article written by a collaboration of people by a company named Today’s Science. Their main goal was to describe the pattern of sleep a human goes through during the night. This cycle is called NREM and REM, non-rapid eye movement and rapid eye movement. They mostly describe what happens during sleep because without sleeping you could not dream. Dreaming occurs during the rapid eye movement cycle of your sleep which is about 90 minutes into your sleeping cycle.
Pollak, Charles P., Michael J. Thorpy, and Jan Yager. "dreams." Health Reference Center. Facts On File, Inc. Web. 24 Oct. 2013.
These authors talked about dreams and how they lead up from history until recent times. They talked about dreams dating from the bible and how they were even important then. They talk about the sleep cycle and how it includes REM and without REM you could not have dreams. They also brought up different scientists theories in which they believed that dreams eliminate unwanted information from the central nervous system. Dreaming may be important in un-cluttering the brain so that new information can be more easily retained in memory. They talk about different types of dreaming such as lucid dreaming, nightmares and night terrors. They also talk a small amount about the sleep disorder narcolepsy.
Rosen, Marvin. "Biology of Sleep." Health Reference Center. Facts On File, Inc. Web. 24 Oct 2013.
The author Marvin Rosen describes the brain like a computer. He starts off by comparing the human brain to a microchip and that no one actually thinks about what is happening inside the microchips when a computer is working. The same goes for our brains, and no one actually thinks about what is going on while we sleep or while we dream it just happens. He defines sleep, the R.E.M. cycles that happen during and he also talks about a brief history of the study of sleep and dreaming. He explains why we sleep, saying that it is a break time for the brain to review all the information during the wakened state. He also talks about why we dream and that is necessary because provide the brain with stimulation that is required to develop and preserve the brain 's nerve pathways. This theory is supported by the fact that infants, whose brains are rapidly developing, spend most of their time in REM sleep.
Rosen, Marvin. "Theories of dreams and application in psychotherapy."Health Reference Center. Facts On File, Inc. Web. 24 Oct. 2013.
The author, Marvin Rosen, elaborately describes the sleep cycle in order for the reader to understand the concept of the Dream. He uses various examples from different psychologists including Sigmund Freud, Fritz Perls, and Carl Jung. Each of these men had a different standpoint on Dream analysis and the way the brain works to compute a dream. Freud believed that there was deeper, metaphorical meanings to the images and sounds in your dreams, Perls believed that there was also meaning except that dreams were basic enough for most everyone to understand the underlying meaning, and Jung believed that the images in dreams were passed down from generations through the nervous system.
“Scientists Discover Why Dreams Are So Weird.” Today 's Science. Infobase Learning, Mar. 1998. Web. 24 Oct. 2013.
This article focuses on the emotions behind a dream. It says the the emotions you experience in the day you also experience in your dream because the limbic system is involved. The limbic system is the part of your brain that deals with emotions, and it is also the part of the brain that largely contributes to dreaming which is why your emotions pertain to your dreams. Other scientists in this article believe that dreams have no psychological significance and are merely the by product of our brains getting rid of excess information from our days.
