Term Essay

The stages of sleep can be broken down into two broad categories: non-REM and REM sleep. Non-REM (rapid eye movement) sleep can be further broken down into four more stages - stages 1-4.

The humankind throughout history has tried to learn and figure out the meaning of dreaming. The interpretations and true meanings of dreams has expanded and has varied over centuries and cultures. Many of the earlier studies were based on culture’s and the interpretation of dreams, but also used as a form of prophecy, inspiration, and guidance. Many people still believe this such, people today beliefs and theories have opened up to a more vast interpretation, they are made up of; dreams are rare brain activity, dreams allow people to reflect on themselves, or that dreams are too massive to be correctly interpret. Although, not a single theory has been proven to this day, science as of why dreams occur is still a mystery.

Have you ever not gotten enough sleep, or cut your sleep short for a class? Show of hands? Alright, well today I will be speaking with you about a subject that is near and dear to all of our hearts. Today I will be talking about sleep, specifically about REM sleep. First off does anyone know what the initials REM even stand for? REM stands for rapid eye movement, and it is the stage of sleep in which most dreams occur. It gets its name from the way your eyes move back and forth in this stage. Though those movements are slower than how your eye would move when you are awake. During a typical night, you cycle between REM and non-REM sleep, but spend the majority of your time asleep in non-REM.

Researchers have classified two definitive types of sleep, REM, otherwise known as rapid eye movement, and non REM and have divided the sleep cycle into four distinct stages. REM sleep is associated with dreaming as most of our dreams occur during this stage. REM waves are very fast and resemble beta waves which indicate that you are awake. REM sleep is usually

In the final stage of sleep called R or REM sleep but also known as Rapid Eye Movement sleep, you will have to progress back through stage N2 to get to REM. In this stage the body temperature rises to a near waking level, eyes begin to move rapidly, and the heart rate becomes faster. More than half of dreams occur in REM sleep. Dreams in this stage will seem more vivid and life like. You can also experience sleep paralysis. This stage occurs every 90

With this in mind, a person’s heart rate slows, and they begin to rest and recharge after a long day. When this person finally dozes off, they undergo cycles of non-REM and REM sleep. Non-REM sleep comes early in sleep and contains deeper, more restful sleep. Dream filled REM sleep comes late in the night and when all dreams occur. Dreams in REM sleep can last anywhere from a few seconds to forty-five minutes long. The transition between the two cycles happens at the same time for each person, regardless of bedtime. The time of this switch between cycles differs for each person. This is the reason for not forcing sleep. This results in a healthy balance of non-REM and REM sleep balance

Every day scientists have been performing sleep and dream tests on people for the past decades but could not come up with an exact reasoning to why we sleep or dream. There are many theories to why we dream they may include that it may be a physiological, biological, or psychological functions but that have not to be answered. But that have not stopped many scientists from coming up with speculations. But we do know that our dream cycle is usual most lavish and finest during the rapid eye movement of sleep also known as the REM stage of sleeping. Dream are still to be considered to be a mystery because they have a litter meaning to them and it hard to recall what happened in the dream. Except the fact that many scientists in the scientific

This stage is believed to help people enter deeper stages of sleep (4). Stage 3 sleep consists of 20-50 percent delta activity and stage 4 sleep of more than 50 percents delta activity (4). Stages 3 and 4 are characterized as being slow wave sleep in addition to being the deepest levels of sleep. Approximately 90 minutes after being asleep, people enter rapid-eye-movement (REM) sleep (4). REM sleep consists of rapid eye movements, a desynchronized EEG, sensitivity to external stimulation, muscle paralysis and dreaming (4).

Our dreams are created by our cerebral cortex, the part of our brain in charge of interpreting and organizing the information we receive from the environment during consciousness. Sleep is divided into many different cycles, one such cycle, REM sleep, involves rapid eye movement and very high brain activity similar to when we are conscious. Scientist believe that our brain receives “random signals from the pons during REM sleep” which our cortex interpret as well and thus the cortex ends up putting together a “story” out of pieces of brain activity. Of course, this all means that if a person were to skip the REM cycle of sleep by not sleeping enough or by altering their sleeping habits to wake up before these periods of time happen, then they wouldn’t have the opportunity to dream. Even so, this has proven that everyone dreams with this in mind, scientists have also proven that lucid dreaming is possible. Experiments done by Stephen LaBerge, leader in the scientific study of lucid

Throughout the centuries, the scientific advances allowed people to come up with many conclusions about biology and the human body. However, there is a major aspect of the neurological and psychological fields that is still not fully understood. The unknown phenomenon that will be discussed in this book are dreams. The importance of dreams is viewed differently in different cultures, and the universal interpretation and purpose of dreams still has yet to be discovered.

During a single night of sleep, a healthy adult goes through multiple different stages which repeat themselves irregularly. Therefore, sleep involves REM (rapid eye movement) sleep and nREM (non rapid eye movement) sleep, which subdivides in stages 1, 2, 3 and 4.

Everyone dreams even if they don’t remember dreaming the next day. Dreams can be disturbing, delightful or bizarre. According to Merriam Webster dreams are a series of thoughts, images or emotions occurring during sleep. A simpler definition of dreams is stories and images our mind creates while we sleep. Dreams can make you feel different types of emotions like happy, sad, angry, or scared. They can also be vivid. The brain is more active during REM(rapid eye movement) sleep, that is when most vivid dreams occur. No one has figured out why we dream but, there are many theories. Researchers say many things about dreams some saya that they have no purpose or meaning while, others say they are necessary for mental , emotional and physical health.

Dreams have been around as long as the first civilization came to be and have been a normal part of human existence. One third of your life is spent sleeping, and of that third, on average you will have spent a total of about six years of it dreaming. Most people dream on average two hours every night, but you can have anywhere from four to seven dreams in one night. According to research, the most common setting for a dream is in your own house. In our dreams we can do anything we want and be whoever we want to be. Our dreams are an escape from reality. While we dream we are unable to control our actions and choose our surroundings. We let our minds take over. Sometimes dreams can be understood in the context of repressed thoughts. Dreaming serves as an outlet for those thoughts and impulses we repress during the day. When we go to sleep at night and slip into our dream state, we feel liberated and behave in a manner that we do not allow ourselves to in our everyday life. Visions and ides can come from your dreams. Often, authors, screenwriters, and even poets turn to their dreams for inspiration. The think quest oracle library goes on to tell about the most well-known of the modern dream

Dreams have fascinated philosophers for thousands of years, but only recently have dreams been subjected to empirical research and concentrated scientific study. Chances are that you’ve often found yourself puzzling over the mysterious content of a dream, or perhaps you’ve wondered why you dream at all.

 REM Sleep (Rapid Eye-Movement Sleep): a stage of sleep associated with dreaming, and characterized by frequent eye movements, suppression of the muscles.
