Theories of Sleeping and Dreaming

Sleep is far more important than people may assume. Sleep is the best way to cope with stress, critical thinking and illness. It helps restore energy level and affects the state of physical and metal well being. There are four stages of the sleep cycle. The first stage is considered the eyes being closed and can be woken without difficulty. This stage may last from 5 to 10 minutes and may cause muscle contractions. The second stage is where the body prepares for deep sleep. The muscles relax, heart rate slows and the body temperature will decrease. During stage three, the brain releases waves known as delta waves. This stage is the transitional period between light and deep sleep (http://www.webmd.com/sleep-disorders/excessive-sleepiness-10/sleep-101). Stage four is considered the deepest sleep stage where sleep walking and bed wetting can occur. In this stage, REM sleep occurs which is rapid eye movement and dreaming occurs due to increase of brain activity but voluntary muscles become paralyzed (http://psychology.about.com/od/statesofconsciousness/a/SleepStages.htm). The five common beliefs about dreaming are: people believe that external stimuli can become incorporated into their dreams, some believe that dreams last only an instant, some claim that they do not dream, penile erections are commonly assumed to be indicative of dreams with sexual content and most people believe that sleep walking and sleep talking only occur only during dreaming. There are two common theories of dreams, one made by Freud who believed that dreams are triggered by unacceptable repressed wishes, often of a sexual nature. He argued that because dreams we experience are merely disguised versions of our real dreams. The other theory made by Hobson’s is based on the observation that during REM sleep, many brain-stem circuits become active and…...

Dreaming According to the Dream Activation Synthesis Theory

...“Analysis dreaming according to the dream activation synthesis theory” The activation-synthesis theory explains us that the messages of dreams are not a meaning. They are only processing of brain system when we sleep. The chemicals in the brain transmit message from one nerve cell to another. This electrical energy randomly stimulates memories found in various area of the brain. Also, we have a need to make sense of our world and even while asleep. The brain takes these chaotic memories and creates a logical story line. This theory best explains my dream which I will describe as follows. In my dream, I met giant cockroaches which were taller than I was. I felt very scared because they were very big and they tried to attack me. I ran fast but I could not escape since there were many of them. Then I woke up with a start. On another day, I dreamed that I was driving on the road skillfully and quickly. While I drove past many cars from left to right and right to left, I felt very proud of my driving skill. Therefore, I will show the relation between real life and dream. In the first case, I had seen a cockroach while taking a shower before going to bed. It ran to my leg, and I very do not like them. That represents my concerns about cockroaches and I clearly remember according to the activation synthesis theory. The second dream happened when I was young. I wanted to be a sports car driver in that time because I thought it was very smart. Also at that time, I think about......

Dreaming

...referral, a trip to the office, or all of the above. So, perplexed that I was unable to do anything I favored to in this class, I contented my self with the fact that we were not learning anything at the moment. Instead, we were able to either listen to the teacher ramble on about something completely off-topic (again), or sit back and enjoy our few minutes (half of an hour) of freedom to think of whatever we wished. Yes… thinking was indeed one of the few things in our life we were not limited to. And best part was that no one got to know what we thought about! Unless, of course, we so smartly decided to tell all the adults what was really going through our minds while they continued to lecture us on unneeded knowledge in our life. As was dreaming. There was the I-dream-to-become-a-rock-star kind of dream, and the I-had-a-funny-dream-last-night dream. People tend to do more of the latter than the former, especially during class. It's what we call today "daydreaming", or, "happily wasting our time". When I think, I think of fiction. Fictional characters that are mine to control, mine to shape, mine to keep, and mine to grant with whatever troublesome characteristic or annoyingly impossible situation I can find for them. When I dream, I dream of those personalities and characteristics in action, about what things made them who they are to exist in my head. The only problem is that I can never fit these onto a piece of paper. I curse my laziness. Any day the teacher......

Annotated Bibliography: Psychology of Dreaming

...Psychology of Dreams For my research project, I am investigating the abstract world of dreams and the theories behind those dreams. Why we dream what we dream, and how, and where dreams come from. There have been many different theories on where dreams come from and how to interpret the dreams of different people. I will be exploring the similarities and differences of those theories along with speculating which theories are the most accurate, taking into consideration recent research on the psychology of dreams and dream interpretation. My main focus will be the world-renowned psychologist, Sigmund Freud. His theories on dreams and the interpretation of dreams are the most widely known and socially accepted theories, but are those theories the most accurate? That is what my research paper will be discussing and examining. This paper will be objective, simply providing the facts about dreams and the different theories regarding dreams and the interpretation of them. I will go in depth with why we dream what we dream, some of the most common dreams that people have, and what the most popular theories are behind the psychology of dreams. My purpose of this paper is to inform my audience of the theories behind dreams and where they come from. I will provide information on the different interpretations of common dreams, the history of dreams, and the basics of the sleeping cycle. My readers are my class peers as well as my instructor. I think that many people know the......

Lucid Dreaming

...tired or bored, one will eventually dream in one way or another. Lucid dreaming is a term created by Frederik van Eeden that is used to describe a dream in which one is aware that he/she is dreaming. This type of dreaming is considered by many as a higher level of consciousness. Most people do not know what lucid dreaming is and those who do rarely are aware of how to realize that they are dreaming, let alone actually manipulate their dreams. Lucid dreaming can have many benefits in one’s life, whether it’s relieving stress, learning or studying, having fun, etc. Also, there is little risk in dreaming lucidly, since dreams do not take place in the physical world. Anything that can benefit many people with little risk should be readily available and encouraged. Dreaming lucidly fits this description yet is not studied often, and on top of that, is not taken very seriously within the scientific community. Lucid dreaming should be a topic that is taught and discussed more often than is currently in everyday life. To understand lucid dreaming, one must understand the two different types of “life”. One of which is waking life, which you probably can guess, refers to one’s life while they are awake. The other of which, is dreaming life, which refers to one’s life while asleep. The special thing about lucid dreaming is that it encompasses both of these ideas into one. That is to say, that you are dreaming and consciously aware of that fact simultaneously. This all......

Lucid Dreaming

...Lucid Dreaming Ayeisa Chavez SPCH 1311 MW 8:30 am Irma Garcia March 6, 2013 Imagine going to bed one night only to wake up in a whole other world where anything your heart and mind desired became reality. Flying over clouds, breathing underwater, going to any part of the world or even getting to be with that person you so much desire wasn’t impossible anymore. Well there is a way that can be done, and that’s through something called lucid dreaming. After listening to this presentation I hope you will have a better understanding of the world of lucid dreaming and how it can be done. I will begin by explaining to you in detail what it is exactly. Then, you will learn a few of the benefits gained by this experience and some dangers. Last, I will give you a few simple steps to how it can be done. Sounds exciting, doesn’t it? I know I was! As explained in an article by Rebecca Turner, Lucid dreaming is the proven ability to become aware while you’re dreaming, to consciously “wake up” inside the dream world and control your dreams. In other words, it’s being able to do as you please while you dream. Marshall Brain researched that when you sleep, your brain goes through several stages of a sleep cycle. The cycle that deals with dreams is REM or rapid eye movement which takes up 20 to 25% of sleep and your brain is basically shut off during this period of time. Your body becomes paralyzed except for the eyelids and the part of the brain that deals with logic is......

Challenging Freudian: Hobson and His Neurophysiological Substrate for Dreaming

...Dreaming is a fascinating and mysterious study field that has been invigorated by the advancement in brain science in the recent few decades. As the leading psychiatrist who thrives in developing the new dream theory on extensive base of brain science, Allan J. Hobson comes to public attention with his Activation-Synthesis hypothesis. He claims to take up what Sigmund Freud, historically the best known dream investigator, has left off in the brain side of dreaming and, further, to revise this far-reaching dream speculation of Freud’s into a more scientifically valid way. However, as the psychological approach to dreams has been preoccupied with Freud’s dream theory in such an extent that the marching on neurophysiological hypothesis has inevitably brought up an uncomfortable disturbance among psychoanalysts. Dating back to twentieth century, Freud reached to the field of mental functioning based on his clinical observations of dream cases. As his censorship-disguise notion becomes outmoded along with the advancement in brain science, the contemporary Freudian psychologist, Mark Solms comes to the rescue. He tries to validate the theoretical inference that Freud has sketched with the newly released experimental data, drawing mainly from brain imaging and lesion study. In spite of the ongoing attempt to bring psychoanalysis back to its prominent role in dream study, Hobson stresses the fact that no amount of tinkering is going to improve the erroneous Freudian......

Sleeping and Dreaming

...Sleeping and Dreaming Rebecca Limon PSY 240 January 14, 2014 April Kindall Sleeping and Dreaming There are four stages of sleep. These stages are known as EEG: stage 1, stage 2, stage 3, and stage 4. When transitioning from alert wakefulness to stage 1, there are alpha waves that punctuate the low voltage, high frequency waves of alert wakefulness. The EEG voltage will increase gradually, while the EEG frequency will decrease gradually, as the individual progresses to stages 2, 3, and 4. According to Ch. 14 of Biopsychology, the stage 2 sleep EEG has a slightly higher amplitude and a lower frequency than the stage 1 EEG; in addition, it is punctuated by two characteristic wave forms: K complexes and sleep spindles. Each K complex is a single large negative wave (upward deflection) followed immediately by a single large positive wave (downward deflection)—see Cash and colleagues (2009). Each sleep spindle is a 1- to 2-second waxing and waning burst of 12- to 14-Hz waves. The stage 3 sleep EEG is defined by the occasional presence of delta waves—the largest and slowest EEG waves, with a frequency of 1 to 2 Hz—whereas the stage 4 sleep EEG is defined by a predominance of delta waves. Once sleepers reach stage 4 EEG sleep, they stay there for a time, and then they retreat back through the stages of sleep to stage 1. There are five common beliefs about dreaming. These beliefs include the following, the first belief is that there are some people who believe that......

Sleeping and Gpa

...Can Sleeping Affect Your GPAs? Our statistics project is about how the amount of sleeping hours can affect your GPA. Researchers have shown that lack of sleeping will affect the ability to study of the students. We are told that sleeping is very important as it restores your energy after a whole day working. Having lack of sleep can weaken the ability to concentrate, stay alert, think critically and solve problems of the student and thus, can affect their academic performance. Is it true and does it differs between different major students? In this project we would like to compare students who are majoring in Arts and Business and how lack of sleep or having more hours of sleeping affects their overall GPAs. Our null hypothesis is that there is no significant difference in the relationship of the hours of sleep and the students' GPAs. We are expecting on our alternative hypothesis that there is a significant difference in that relationship. In order to conduct our research, we will select randomly 2 samples of 15 Art students and 15 Business major students. We agreed that less than 4 hours of sleep is not enough to perform well in school and having more than 4 hours of sleep is beneficial for the students to do well academically. Why should our project be considered? We think this is important for students to know whether sleeping can have a significant impact on their academic performance or not. Being acknowledged about the importance of sleep can help the......

Essay on Dreaming

...What Does it Mean to Dream? What does it mean to dream? Why do we dream? In fact, what is dreaming really? In this world, a lot of definitions and answers were formulated to solve this question. Up till now, nobody has actually defined clearly what is dreaming or why do we exactly dream. People after all have different contentions from each other and opinions can play a heavy role in determining a decision. Because of this a lot of prominent psychologists developed different definitions to the meaning of dream. Even before that, Philosophists have already pondered on such an interesting concept. Some say that dreams come from an external source, wanting to communicate with us or convey to us an important message. Others say that dreaming is related to fulfilment… meaning that a dream is essentially something you wish to happen but are either actively repressing it or subconsciously doing it to yourself. Others say that dreams are a reflection of waking life… of what we have experienced translated unto the realm of dreams. But what is dreaming really all about? Dream, otherwise known as Morpheus or Oneiros, and his willy antics extends itself to the realm he presides on. Just like the enigmatic being, the landscape is unpredictable, changing and foreign. It may be rapid in its change or it changes itself in a snail’s pace. There is no limitations to the human mind after all. Anything that can, could and couldn’t happen can be easily conceived and achieved by the mere......

Lucid Dreaming

... Dr. King Lucid Dreaming Holzinger (2009), suggests that dreams have been a major importance to cultures throughout the ages. Native Americans viewed dreams as portals to the spirit world, paths to prophecy and quests. A common phenomenon states, there is an experience in which one is aware that one is dreaming and is able to control what happens in the dream. This experience is known as lucid dreaming. Aristotle may have been the first to write about lucid dreaming, although he did not have a term for it (Holzinger B. , 2009). And some Tibetan Buddhists have been practicing something like lucid dreaming for a long time. In Tibetan Buddhism, it was practiced as a form of yoga, called dream yoga, from the eighth century. The goal of dream yoga is to examine your consciousness and bring you to a constant state of awareness. A big part of the belief system of Buddhism is recognizing the world for what it is, free from deception. A lucid dreamer recognizes the dream world for what it is, a dream (Holzinger B. , 2009). A Dutch psychiatrist named Frederik van Eeden came up with the term for lucid dreams in 1913. He claimed that there are nine well-defined types of dreams in all, including ordinary, symbolic and vivid dreams. He recorded several of his own lucid dreams, and his thoughts during them and upon awakening. He remarked that they often involved flying (Holzinger B. , 2009). Lucid dreaming is normally a rare experience. Though most......

...as much sleep as they did as pre-adolescents (in general, 8.5 to 9.25 hours each night). (Carskadon et al., 1980) Daytime sleepiness increases — for some, to pathological levels — even when an adolescent’s schedule provides for optimal amounts of sleep. (Carskadon, Vieri, Acebo, 1993) Adolescents’ sleep patterns undergo a phase delay, that is, a tendency toward later times, for both sleeping and waking. Studies show that the typical high school student’s natural time to fall asleep is 11:00 pm or later. (Wolfson and Carskadon, 1998) 2 A D O L E S C E N T S L E E P N E E D S A N D PA T T E R N S W National Sleep Foundation B E H AV I O R A L A N D P S Y C H O S O C I A L PAT T E R N S Many U.S. adolescents do not get enough sleep, especially during the week. Survey data show that average total sleep time during the school week decreases from 7 hours, 42 minutes in 13 year olds to 7 hours, 4 minutes in 19 year olds. (Wolfson and Carskadon, 1998) Only 15 percent of adolescents reported sleeping 8.5 or more hours on school nights, and 26 percent of students reported typically sleeping 6.5 hours or less each school night. Adolescents have irregular sleep patterns; in particular, their weekend sleep schedules are much different than their weekday schedules, to some extent as a direct consequence of weekday sleep loss. These differences include both the quantity and the timing of sleep. One study of more than 3,000 adolescents showed that the average increase of......

Dreaming

...Hardman 11/8/2012 Psych 111 Dreaming A dream is a succession of images, sounds, ideas and emotions that we experience involuntarily while sleeping. Everyone has dreamed at least once in their life, even if they don’t remember it. As a matter of fact everyone experiences six to eight dreams per night, and out of the eight hours of sleep we’re supposed to get each night, two of them are spent dreaming. People aren’t the only animals that can dream. Actually, every mammal is known to have dreams at night, and even some birds. Dreams usually occur during the “rapid eye movement” stage of our sleep, when brain function is high, almost as high as when we’re awake. We most likely remember the dreams that we have during the REM stage because the brain is functioning at such a high rate, but we also dream during other stages of sleep. Those dreams are just harder to remember because the brain is not functioning at the level that it would be during the REM stage. As we all know, dreams can range from exciting and pleasurable, to scary and terrifying. I know that I personally have woken up terrified from a dream, and didn’t want to go back to sleep because I didn’t want to encounter what I was dreaming about again. Usually, we can’t control what we dream about. However, it is a proven fact that a person can induce lucid dreaming if they work at it. Lucid dreaming is when the person who is dreaming is aware of the fact that they are dreaming, and can therefor control......

Sleeping

...researchers suggest that sleep deprivation should be recognized with the same seriousness that has been associated with the societal impact of alcohol. When you get tired fatigue sets in. Fatigue is a lingering tiredness that is constant and limiting. With fatigue, you have unexplained, persistent, and relapsing exhaustion. This can cause a lack of attention at work or at school. Retaining information just does not compute correctly as the brain needs a certain amount of sleep in order to function normally. Your body will basically shut down and you will experience different signals that will affect your perceptions, etc. There are many different ways that can affect fatigue, but generally speaking it is through some sort of sleeping disorder that needs correction. Some of the causes of sleep disturbances include genetics, night shift work, medications, and aging. All have a part in the sleep disturbance that can affect our lives daily. Other examples research communicates to us might be a physical disturbance that produces pain. Medical issues such as asthma, diabetes, psychiatric disorders, or environmental issues are highly attributable to sleep disturbances ( Korenblum, 2012). Long-term or chronic insomnia can be caused by factors such as depression, chronic stress, and pain or discomfort at night. Factors like sleep deprivation also magnifies alcohol's effects on the body, so a fatigued person who drinks will become much more impaired......
