Dreams have puzzled philosophers for thousands of years and only recently dreams have been subjected to empirical research and scientific study. So what are dreams? Dreams are any thoughts, images, or emotions that are expressed during certain stages of sleep, mostly during stage five, known as REM, where the brain increases in activity. Dreams can range from being extremely vivid to very vague, filled with varying types of emotions such as joy, sadness, or fright, and can also be completely clear and understandable or totally unclear and confusing.
“People say, 'I'm going to sleep now,' as if it were nothing. But it's really a bizarre activity. 'For the next several hours, while the sun is gone, I'm going to become unconscious, temporarily losing command over everything I know and understand. When the sun returns, I will resume my life.” This quote by George Carlin is a perfect description of the odd nature of sleep and dreams. Dreams are something that most human beings experience on a nightly basis. Because we all dream, the mysterious topic of dreams becomes something we are all interested in. It is an amazing concept that has us waking up feeling good at times and terrified at others. The documentary, “Why Do
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.
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
Robert Bly’s “Waking from Sleep” explores the thoughts and events that occur at night as the country recovers from the war that has just occurred. In the first stanza of the poem, the narrator is addressing the war, the reader can confirm this because he states “tiny explosions at the waterlines” (line2) and “wind of the salty blood” (line 3). The reader is immediately informed that a war has occurred because of the navies setting forth, tiny explosions and salty blood. In the second stanza, the narrator is describing the months after the war. The memories still remain of the tragic events that have occurred. In the third stanza things for the narrator start looking brighter. The country is now rising from bed and waking up. However, the memories of those who have passed away are remembered as their shouts are heard from the harbor. Throughout the fourth, and final stanza the country is healing. The country is singing, and dancing in the kitchen. The author portrays that those who are lost are never forgotten, and the country is reminded of their memories every morning at dawn when silence sweeps the nation.
Sleep timing, duration, and quality can influence the release of growth hormone, cortisol, leptin, and ghrelin. The sleep wake cycle also influences insulin secretion. Reduced sleep can have adverse effects on metabolism and endocrine function. Disruptions in circadian rhythm and the sleep wake cycle regulate the release of hypothalamic activating and inactivating factors that influence the release of pituitary hormones and sympathetic and parasympathic activity. With reduced sleep, a study found increased evening cortisol levels, decreased glucose tolerance and glucose sensitivity, and a slight elevation of GH while awake (Leproult & Van Cauter, 2009). Because the student sleeps less than 8 hours a night, this will reduce the leptin level and elevate ghrelin, so the appetite of the student will probably increase, thus increasing the BMI as well. Ghrelin works to stimulate the appetite. (Taheri, Lin,
However, the article also goes into details about REM sleep and NREM sleep, which explains the different sleep stages. Furthermore the article also goes on to explain how REM sleep deprivation can affect memory and NREM sleep interruptions can affect facial emotional expressions. Although research from the article provides evidence showing that NERM and REM sleep are great places to process and reprocess emotions. Article can be used to assist with emotions topic.
“Dreams seem to help us process emotions by encoding and constructing memories of them. What we see and experience in our dreams might not necessarily be real, but the emotions attached to these experiences certainly are. Our dream stories essentially try to strip the emotion out of a certain experience by creating a memory of it. This way, the emotion itself is no longer active. This mechanism fulfills an important role because when we don’t process our emotions, especially negative ones, this increases personal worry and anxiety. In fact, severe REM sleep-deprivation is increasingly correlated
The precise science behind dreams has baffled psychologists for years. Most of these dreams that are constantly studied are not all that enchanting as the name suggests. The grotesque side of these images of the subconscious are called nightmares. When a person experiences a nightmare, heart pounding, sweating, and nervousness occur. These sensations are due to the amount of frightening content of the dream. In turn, the subconscious has the ability to overpower the body outwardly. From research on the causes of nightmares, affected age groups, and how the brain is affected, nightmares can teach humans a lot about the inner workings of their mind.
When we receive proper amounts of sleep, we wake up feeling refreshed and ready for the day’s challenges. Sleep can also affect how we feel and perform the day’s tasks as well as how we look. Sleep was once known as a passive state but is now known to be a highly active process during which the day’s events are processed and energy is restored. The sleep cycle involves two distinct phases that alternate cyclically from light sleep to deep then deeper and deepest sleep throughout the sleep period. There are two main phases of sleep: non-rapid eye movement (NREM) and rapid eye movement (REM) sleep, during which dreaming occurs.
The goal of this study was to investigate the role of sleep in the regulation of emotional reactivity and mood, and in particular the role of rapid eye movement (REM) sleep. The research team led by Rosales-Lagarde measured the impact of total sleep deprivation (TSD) by evaluating subjective responses to frustration and aversive stimuli. It was found that coping skills and emotional regulatory abilities were decreased along with decision-making skills following REM sleep disturbances. It was also found that the subjects that experienced disturbances in REM sleep displayed a greater degree of impulsiveness when faced with a risky decision and favored utilitarian judgments. The data was collected using functional magnetic resonance imaging (fMRI) imaging of the brain during the various stages of the experiment, and during the administration of the Emotional Reactivity Task. It was found that there is a greater and longer lasting activation of the amygdala while viewing negative stimuli, and specifically following TSD. This study was based on previous research that suggests that REM sleep plays a significant role in emotional regulation, as brain areas associated with emotion are specifically activated during REM sleep cycles. These include the amygdaloid complex, medial and orbital frontal cortices, and posterior association areas.
Have you ever wondered why we have dreams? Dreaming is described in varies ways. Many people in the early days interpreted dreams as a way of communicating with god. Messages were said to be sent through dreams to communicate with the immortals. Sigmund Freud believed that every dream had a meaning behind it. There were also many other psychologists with other perspectives on dreams. Sleep is also a major part of our everyday lives. Without sleep, we would have no energy to do our normal everyday routines. Sleep has many stages and also had REM and NREM sleep. Sleeping is very critical for people. There are also certain hours that a person should sleep or else they will be sleep deprived. The following will discuss the stages of sleeping, sleep deprivation, and will also talk about why we dream, and what it has to do with our everyday lives.
Since the beginning of time humans have been intrigued by what happens in their brains at night; especially dreams. We can see that all the way from Ancient history to Medieval to Classical and now in modern history, humans’ views on Dreams and Sleep have played huge roles. According to Gackenbach and Sheikh (1991) in some cultures, like Ancient Egypt, people with “vivid and significant” dreams were considered blessed. A philosophical question that may never be answered is that of the meaning of dreams. Throughout history man has pondered the meaning of dreams. Philosophers often bounce to Hippocrates and Aristotle for the philosophy behind these questions, however even before Hippocrates, Ancient Indians believed that dreams meant two things. The first was inner desires, in that each dream you had reflected your deepest wishes. The second is that dreams are when souls leave the body and are being guided through dreams until woken up. William C. Dement, once said “I believe that the study of sleep became a true scientific field in 1953.” He said that because of his ingenious findings. Dement conducted an experiment on REM Deprivation. He deprived 8 subjects of REM sleep for 7 days and, the study showed that as time went on the subjects went into REM rebound, which is when the body enters into REM sleep more frequently because of a lack of REM sleep. REM rebound shows the importance of REM sleep to the body.
Dreams are a useful and often overlooked tool in psychoanalysis. They provide a way to become aware of one’s unconscious thoughts. Dreams can clarify and sort emotions in new and unexpected ways. One’s most vivid dreams occur during the REM cycle of sleep, these dreams bring one’s body into an excited state which allows the brain to store long-term memories and alter feelings. For the average person, rapid eye movement sleep accounts for one fourth of sleeping time and occurs in bi-hourly cycles. Though much is still unknown about the exact meaning of dreams, scientists do know that dreams play a role is shaping our emotional responses and reactions to the world around us. This leads us to the questions: what does a person 's dream say
“We all must sleep. From the time before birth, through the long years of our life, to the very day that we die, a rhythm of sleep and wakefulness goes endlessly on” (Silverstein 1). Considering that a person spends about one third of their life asleep, it is apparent that sleep is crucial for the human body and mind. While sleeping, a person might snore, turnover, mumble, talk, or even walk. Stray thoughts drift in and out of the mind and are sometimes woven into the fanciful stories and scenes that we call dreams. The true meaning of what dreams are and why they occur has been speculated for many centuries and today there are numerous theories on why the human mind dreams. The state of unconsciousness, known as dreaming, is a universal human experience that is distinguished by sensory, cognitive, and emotional occurrences during sleep.
