On Sleep and Dreaming

Sleep is a state of altered consciousness, characterized by certain patterns of the brains activity and inactivity. An altered state of consciousness is when a person is not completely aware of their surroundings. Some researchers believe that we sleep to clear our minds of useless information. Other people believe that it is a type of primitive hibernation: we sleep to conserve energy.

Humans, like any other animals, sleep. No one fully understands why we have to sleep. But if we are deprived of sleep for too long, we die. It is as true as dreams and dreaming. The longer a person sleeps they will reach an advanced stage in sleep where the body begins to experience rapid eye movement(REM). Humans experience most of their dreams during the REM period. While a person is awake or asleep, the mind consciousness functions as a model of the world that was constructed by our brain. While awake, the mind takes in informations throughout the day that it can remember.

“Why do we sleep?” is a very popular questions that many humans ask today. Sleep is very sufficient to the human body. If it was not important, then God would not have designed for a third of our life to be occupied by sleep. During this time period, many people are interested to know what is a good amount of sleep and what are the harmful effects to not getting enough sleep.

There are a few factors that are essential for life such as breathing or eating, but one of the most essential factor is sleep. Even though the amount of sleep people need differs from one individual to another, the fact is that eventually everyone needs to sleep. People know the importance of sleep, but due to the increased workload and the pressure of society people are getting less sleep. As a result, there has been an increase interest on the effects lack of sleep has on the mind especially the memory of a person. Many questions arose about the relationship between sleep and memory due to the fact most high school and college students have become sleep deprived. For example, does more sleep mean higher grades?

Consciousness is your awakened state of mind in which you are cognizant of and are able to distinguish between realities while also being preemptive to one’s thoughts, emotions, and feelings through the establishment of the fundamental aspect of student-object relationships in which one is not only aware and mindful of his surroundings, but oneself as well at any given moment as the present renders sentiments of familiarity, presumably rectifying preconceived notions that consciousness is merely an illusion and is rather more so a universal force and a collective body of existence and self-realization.

The average human spends about 25 years of their life sleeping. That is equal to one-third of a person’s life. So if sleep is vital and common among every single human, what do you know about it? What happens when we sleep (Attention Grabber)? Before the 1950s, scientists believed that the brain would just “shut off” when we would go to sleep. It wasn’t until the discovery of the Rapid Eye Movement (REM) state that scientists really looked into what happens in the brain while we are asleep. Studies have found that we go through a cycle of stages during sleep, and it is important for our health (Orientation to Topic). Today, I am going to inform you about what really happens when we sleep, and some issues that are found among it (Specific Purpose). In order to really understand this worldwide commonality, you need to know some background on sleep, the stages in the cycle, and some common disorders (Central Idea). I have taken a year long psychology course that went into depth on sleep psychology, and I have done extensive research on the topic to better grasp it (Statement of Credibility). I want to inform you on sleep so you can understand what happens when you close your eyes every night, and so you can detect any irregularities in your sleep pattern (Statement of Goodwill). First, I will give a background of why and how we know to sleep, then I will explain the stages in the sleep cycle, and finally I will tell you about some common disorders (Preview).

Sleep is undoubtedly one of the most essential requirements for the human body to function properly. It plays a very important role in ensuring the wellness of the human body both physically as well as mentally. In fact, the importance of sleep is clear from the fact that it helps you in maintaining a good lifestyle throughout our entire lifetime. Not only does it help maintain our physical and mental health; rather it also helps in maintaining a decent and healthy lifestyle along with ensuring safety from a number of fatal diseases. It is usually said that the mood in which you wake up is largely dependent on the type of sleep you have been in. This in itself is a big proof of the importance of sleep in our lives. While sleeping, our body finally gets its share of rest and it also gets ample time in rejuvenating from all the wear and tear that it went through during the entire day. Not only this, the body is in its own working condition when we are sleeping as this is the time when it supports the healthy functioning of the brain as well as physical attributes of our body.

In Module 9 on the topic of Sleep and Dreams, was an interesting topic that was discussed in class as many people normally question why and how we dream. There isn’t a specific reason in how dreams are functioned but there are different interpretations and stereotypes that people think have meanings and others that don’t.

Throughout the night most people do not even notice all the different stages of sleep that they go into without even thinking about it. In an entire night of sleep a person goes through four different stages of sleep. When a person first lies down before their body even reaches the first level of sleep they lay there in a relaxed state slowing all of their natural body activities In the first actual

Sleep occurs in in cycles; stage 1, stage 2, stage 3, and stage 4. Stage 5 sleep is when you go into REM sleep and dreams occur. Each stage is differentiated by the amount of electrical waves put off, the frequencies that they resonate, and where the waves are coming from. For the most part your brain puts off low, high voltage delta waves while it’s in stage 3 and 4 also known as “deep sleep” (Rosen, 31). The most common theory on why we actually need sleep and why we dream is that it helps our brains sort out information that we may or may not need. With continuous sleep deprivation our brains cannot do this

Sleeping is extremely important for all mammals, but humans especially. Without sleep we are unable to function properly and at our fullest abilities. When we sleep we grow, and it is an opportunity for us to dream which has many benefits. Sleep is also a way for us to relieve ourselves of stress.

 The goal is to avoid, "clocks on collision," and to allow internal clocks to match external clocks, this is why night shifts are often on weekly rotation.

In the novel, Waiting for the Barbarians by J.M Coetzee, the magistrate’s progressive, non-linear dreams are a parallel to his growing involvement with the barbarians and his growing distaste for the empire. The great psychoanalyst, Sigmund Freud said, “The interpretation of dreams is the royal road to a knowledge of the unconscious.” In every dream there is a hidden meaning and when the reader starts analyzing the magistrate’s dreams he reveals that he is oddly attracted to the barbarians and knows he should not get involved and it will be a trial to get close to them.

Why is sleep so important to us? There have been studies done that suggest that sleep deprivation can be detrimental to or decrease the function of our immune systems. Just think, how often was it that after many days of continual sleep deprivation did you start to think that you had a cold? Sleep deprivation can also result in a decrease in core body temperature, decrease in the release of growth hormone, and possible cause an increase in heart rate variability. Sleep also seems to be important in order for our nervous system to work properly. Without sufficient amount of sleep, our behavior and our ability to do things are impaired. We feel drowsy and are unable to concentrate after not getting enough sleep. With enough sleep deprivation, it has been found that some begin to hallucinate and develop mood swings. Higher-ordered cognitive task become more difficult to do where it has been shown that tests that require speed and accuracy have lower results compared to those that are not sleep deprived. Judgment is also impaired; it has been tested that riskier behavior is more likely to occur when sleep deprived. (2).This is part of the reason why you should not drive when you are sleep deprived. Aside from the risk of falling asleep at the wheel, since judgment is
