Five Stages: The National Sleep When The Human Brain

Dreaming, although a substantial component of our nighttime lives, remains somewhat of an enigma due to the fact that it occurs while we are unconscious. The inaccessibility of the unconscious mind weakens full analysis and comprehension of dreaming which researchers have been attempting to accomplish. However, over the years many researchers have elucidated many mysteries about dreams, such as when we dream, why we dream, and what we dream about, in order to bring forth an understanding of dreams as well as identify

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.

Although newborn infants spend about half of their sixteen to eighteen hours of sleep time a day in REM sleep, adults spend only about an hour and a half in REM sleep. (1) This difference in both amount and percentage of REM sleep between infants and adults indicates the importance of REM sleep, or of dreams, in development. Several dream researchers have hypothesized that REM sleep may play an important role in infant brain development by providing an internal source of powerful stimulation which would prepare the baby for the almost infinite "world of stimulation it will soon have to face" and also by facilitating the "maturation of the nervous system." (1)

“The average person spends a total of about six years dreaming - 2 hours each night - although one third of our lives is spent sleeping” (“Dreams”). Everybody that goes to sleep, dreams. Dreams are a huge part of individuals because they experience dreaming every time they go to sleep. However, no one exactly knows what are dreams define. Even though people are aware of their dreams, they do not know when they dream. Dreams are emotions, thoughts, images, and sensations that happen while sleeping. They cannot be controlled, or so many people believe, so not anything that happens in your dreams are in people’s control. Scientists discovered that dreaming happens in rapid eye movement (REM) stage of sleep. Another thing about dreams is that

Dreams are series of thought, stories, ideas, emotions that happen unintentionally in the mind during certain stages of sleep. Human sleep occurs in several cycles during the night, each cycles consisting of five stages. Light sleep to very deep sleep are ranging during the first four stages, EEG machine shows that the brain activities are decreasing by demonstrating the electrical wave rhythms from first to fourth stage. The four stages can categorized as non-REM sleep (or slow-wave sleep). However, during the fifth stage, there are increased activity of the brain which is associated with rapid eye movement (REM). Due to the increased activity of the brain, most of the dreams happen during REM sleep. People dreams all night long. According to scientific American, each person dreams three to five times per night, some may up to seven

The average person sleeps around four months a year, begging the question why do humans dedicate such a large portion of our time asleep? One of the key components of sleep are dreams, many psychologists have attempted to figure out why dreams are beneficial to us, some of these theories include: Wish-fulfillment, problem solving, replay, and activation-synthesis. Through analyses of my dream, I will demonstrate that activation-synthesis is the most logical explanation as to why we dream.

When people sleep their brain’s activity changes in characteristic ways over the course of one night. These sleep patterns are classified into two main kinds of sleep – rapid-eye movement or REM and non-rapid eye movement or NREM sleep. REM sleep is most often associated with dreaming and it is thought that it assists in brain development especially in the early stages

A normal night's sleep is when a person successfully goes through all five stages of sleeping. The first stage is when you are lightly sleeping and muscle activity starts slowing down a little. You then start slowing your breathing and heart rate down, as well as your body temperature. The 3rd stage is what is called deep sleep. Deep sleep is whenever your brain start to generate delta waves. The next stage is number 4. This stage is whenever your body is in a very deep sleep and your brain is producing delta waves. The last stage of sleep is the 5th. While in this stage a person may start having rapid eye movement. This is also the stage wear dreaming occurs. It is always important to get a good and full night's rest. Not sleeping can cause

Science has shown us that when we sleep there are five sleep stages. These stages move from light sleep to deep sleep and finally ending in REM (rapid eye movement) sleep. REM sleep periods occur approximately every sixty to ninety minuets through out the night. This is where the dreams are the most vivid and most often remembered. The REM sleep stage is characterized by rapid eye movement, increase heart rate and breathing, and elevated blood pressure. In an eight hour night there may be four to six dream periods, which is surprising since you often cannot remember even one

Stage 1 of NREM is the lightest sleep, it lasts about 10 minutes and is presents only 5% of our total sleep time. During this stage we are transitioning from being awake to falling asleep. Our eyes move slowly as well as brain waves and muscle activity begins to decrease. Many people who are in this stage may also experience hypnic myoclonia; sudden muscle contractions. Following stage 1 is stage 2 a deeper sleep, because a person passes through this stage many times it accounts for 50% of our total sleep. When entering stage 2 eye movement stops, heart rate slows, and brain activity decreases, with occasional rapid waves called sleep spindles. Stage 3 and stage 4 is a deep sleep, it is the most difficult to awaken someone from this stage. These stages are often called “slow wave sleep” (SWS) or “delta sleep”. Stage 3 and 4 are characterized by delta waves, which are very slow brain waves with a high amplitude, there is no eye movement or muscle activity and both temperature and blood pressure decreases. Children might experience night terrors, and bedwetting during SWS, and those who wake up from SWS often feel confused and disoriented for several

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

Sleep is the resting period so the body can eliminate muscle waste, repair cells, strengthen immune system, and recover mental flexibility, attention and creativity. There are four stages we go through while we sleep. In stage 1 , brain waves become small/irregular and drift to edge of consciousness (light sleep) where it proceeds to start stage 2 where the brain emits short bursts of rapid and high-peak waves (sleep spindles). In Stage 3 Brain waves stage 2 + some high peak slow delta waves (slow breath/hard to wake) and last stage, is when the brain emits delta waves and is in deep sleep.

Dreams are very unique and many people have theorized about what a dream 's meaning or purpose is, and what affects them. In most present day studies, more vivid dreams have been linked to the stage of sleep called REM (rapid eye movement) sleep. REM dreams are emotional, bizarre, and sometimes so vivid we may confuse them with reality. Most commonly, a dream’s story line incorporates traces of previous day’s experiences and preoccupations. Unless a person is awakened during REM stage of sleep or the dream is exceedingly vivid or intense, most people don’t remember anything about their dreams during REM sleep. This is likely due to the fact that during REM sleep, our brain essentially turns off the ability to encode,or create, new memories.

A dream is a series of thoughts, images, or emotions occurring during sleep. A team of French researchers found that dreams are generated by the brainstem. The average person can have up to seven dreams a night. The amount of time dreams can last vary. They can be anywhere from a few seconds to two hours. Dreams last longer as the night progresses.

People are not required to be sleep to be able to dream. However, the stage that dreams occur is called REM, Rapid Eye Movement. REM is one of the five stages of sleep. The other stages consist of; stage 1: a light sleep, stage 2: eye movement and brain waves slow down, stage 3: extremely slow brain waves, so very little to no brain activity, stage 4: deep sleep, and the final stage is REM, when one’s eyes are constantly moving beneath the eye lid and muscles become temporarily paralyzed. REM is the stage were dreams occur. The REM stage happens every 90 to 110 minutes which is a complete sleep cycle. People typically have around three to four sleep cycles each night. During the first REM period of the night, a dream can last as long as five to ten minutes. Eventually, the dream process can last as long as thirty to
