Sleep Paralysis
Did you ever awaken and find yourself unable to move? Perhaps you sensed a presence in your room or a pressure on your chest. This is sleep paralysis. It is a common disorder that affects millions of people. Most believe it occurs as we are on the edge of REM sleep. The disorder has been connected with such hallucinogenic events such as alien abduction or an evil presence. Sleep paralysis is an inability to move or speak, occasionally accompanied by hallucinations, for up to several minutes upon awakening or just before falling asleep.
The symptoms of sleep paralysis are often associated with REM sleep. This is because during REM sleep, except for the diaphragm, we are more or less paralyzed from the neck down as we dream (Regestein 30). It is when we enter this dream world or exit we can become a victim of sleep paralysis. Sleep paralysis at the onset of nap was well described by a patient of Edward Binns, a physician writing in the 1850s, about what he termed “day-mares” (Mendelson 223):
During the intensely hot summer of 1825, I experienced an attack of this affliction. Immediately after dining, I threw myself on my back upon a sofa, and, before I was aware was seized with difficult respiration, extreme dread, and the utter incapability of motion or speech. I could neither move nor cry, while the breath came from my chest in broken and suffocating paroxysms. During all this time I was perfectly awake; I saw the light glaring in the windows in broad sultry streams; I felt the intense heat of the day pervading my frame; and heard distinctly the different noises in the street, and even the ticking of my own watch, which I had placed on the cushion beside me; I had at the same time, the consciousness of flie...

...ms, science does not have many answers. There is so much unknown about why our bodies need to sleep and dream, and the disorders that are caused when we do not sleep properly. Sleep paralysis is but a small part of the mystery of sleep: as science unravels this mystery we may know more about the causes of sleep paralysis.
The phenomenon of sleep paralysis can be a frightening experience: many who suffer can feel tremendous anxiety and fear, even though occurrences are considered as harmless as a bad dream. The disorder does not discriminate on the basis of race or gender, but age sometimes is a factor. Treatment for sleep paralysis is limited; in general, doctors treat the disorders linked to sleep paralysis such as sleep apnea or narcolepsy. Sleep paralysis continues to be one of the many mysteries of the human brain, which science will continue to investigate.
“I slept… but I was disturbed by the wildest dreams. I thought I saw Elizabeth…. as I imprinted the first kiss on her lips, they became livid with the hue of death…and I thought that I held the corpse of my dead mother in my arms…and I saw the grave-worms crawling in the folds of the flannel” (43).
THESIS STATEMENT: Narcolepsy is a sleep disorder that has a specific medical definition, life-changing symptoms, and there are ways in how people treat it.
Imagine you are in a boring lecture and you start to drift to sleep, usually you can manage to force yourself to wake up. This may be common occurrence but try to imagine falling asleep while driving or walking. These situations seem more rare. A narcoleptic’s body doesn’t care what it is doing when it goes into these paralyzed sleeping episodes. The sudden overwhelming feeling drives the narcoleptic person to fall asleep. One type of episode that they experience is called cataplexy, which is usually caused by some stressful situation or other common activities such as laughing or running (6). During these periods the person suffers from muscle weakness and paralysis. Although the person appears to be sleeping, they are still conscious, but unable to move. They can hear and feel but cannot react to stimulation. For this reason narcolepsy is a very dangerous condition to have without receiving treatment because serious vehicle accidents can result as well as an general inability to succeed in school (6).
W. Somerset Maugham’s The Moon and Sixpence is essentially a novel about a man’s struggle to free himself from the restrictions of society and to act out his most passionate desire--to paint. However, Maugham’s novel is also a story of its time and therefore reflects popular theories and ideas that were prevalent at the time of its writing. Included in these ideas is Hysteria, mentioned clearly when the narrators describes the doctor’s view of Blanche’s attempt to kill herself as “just a hysterical woman who had quarreled with her lover...it was constantly happening. (Maugham 123). The following will describe the development, symptoms and treatment of Hysteria.
As stated in the text book, hallucination during Sleep Paralysis also occurs due to the sudden high blood pressure in the human brain and the change in the membrane potential of the neurons in the visual and/or auditory cortex. What this means is that one person starts to feel fear or terror when under the state of paralysis, it causes the blood pressure in the brain to increase. The emotion of fear is stated to be perceived in a structure called amygdala in the brain. The amygdala tends to be a small structure which is deep inside the brain and has several distinct nuclei which are the following: medial, lateral, basal, and central. According to the article “Sleep paralysis episode frequency and number, types, and structure of associated hallucinations”, the lateral nucleus seems to receive input from thalamus and cortical sensory and association areas. Then after this happens, the basolateral nucleus integrate the input as fear and send the information to the central nucleus, from which a major output transmits through projections to the hypothalamus and brainstem autonomic areas.
Narcolepsy has been above looked for years beforehand knowing a patient has the illness, it is a quickly producing awareness and is continually altering people and their families lives. With nap materializing to be not merely the ultimate pastime, but additionally a survival imperative, the earth of nap scutiny is quite large, bragging countless disparate spans of study. By scrutinizing phenomena like nap disorders neurobiologists can yearn to comprehend the mechanisms of normative nap, in supplement to perfecting treatment for suffers. Narcolepsy is one such disorder that affects an approximated 250, 000 or 1 in 2000 Americans; comparable numbers are approximated for Parkinson's or countless sclerosis (mayo-foundation). An comprehensive, nevertheless oftentimes misdiagnosed illness (fewer than 50, 000 are cognizant of their condition), narcolepsy can be delineated by chronic daytime sleepiness, cataplexy, nap paralysis, and hypanogic hallucinations (rare-disease). The last three of the tetrad of symptoms additionally transpire in non-narcoleptic individuals; nap episodes are the main determinant in diagnosis. Merely 20 to 25 percent of narcoleptics tolerate from all four symptoms (mayo-foundation). This paper has countless goals, all of that involve elucidating the illness and its symptoms in disparate contexts. In order to do this nap will main be elucidated in a slight detail, pursued by a biological and psychological treatment of narcolepsy. Scutiny of narcolepsy and its implications for the upcoming displays steps to be grabbed in order to garner a larger understanding this particular brain/behavior relationship.
The Spleen by Anne Finch, the Countess of Winchelsea, presents an interesting poetic illustration of depression in the spleen. The spleen for Finch is an enigma, it is mysterious, shape-shifting, and melancholic. Melancholy leads the subject to flashes of a grander, terrifying emotion: the sublime. The subject of Finch’s Pindaric ode experiences the sublime, and yet has the uncanny ability to reflect and reason on the feeling with acuity--even though the subject suffers from depression, which in effect dulls sensory information. The fact that she intensely perceives the sublime suggests a paradox where dulled senses can produce a penetrative emotional episode. To understand the paradox, the theory of the sublime and Finch’s engagement with the sublime in The Spleen must be traced to conceive the state of the dulled mind in the thrall of an infinite, and transcendent wave of emotion. The focus of this essay is that Finch understands that Dullness, as a by-product of depression, enables rational thought during a sublime experience. Furthermore, she thus illustrates her experience through images where she emphasizes her sensory information and her feelings, which were supposedly numbed by depression. Her feelings, indicated in The Spleen, are the crux to how Finch is able to simultaneously feel numb, and process the sublime.
The discovery of rapid eye movement (REM) sleep suggested that sleep was not, as it was thought to be, a dormant state but rather a mentally dynamic one. Your brain is, in fact, very active in this state, almost to the level at which it is when a person is awake. Yet during this active stage in which most dreams occur, the movements of the rest of the body are completely stilled. To imagine this paralysis during dreams not occurring is a frightful image, since in many cases dreams are violent and active. When the neurotransmitters that control the movement of the body do not work properly the person develops REM sleep behavioral disorder (RBD).
Hypnogogic state also known as Hypnagogia, is the transition between sleeping and awake where dreams are mixed with reality including sight, sound, and other sensations. Hypnogogic state is the start of consciousness, and is responsible for the birth of lucid dreaming, hallucinations, out of body experiences, and sleep paralysis. It is possible to induce yourself into Hypnogogic state by deep meditation. People claiming that they experienced paranormal events like sleep paralysis, out of body experience, alien abductions, and night time visitions, and other ghostly encounters likely confronted Hypnagogia. According to Edgar Allen Poe “Only, when I am on the brink of sleep, with the consciousness that I am so…” (Turner, 2014).
Several studies found that alcohol abuse and suicidal ideation was usually accompanied by trauma related insomnia and nightmares. In a longitudinal study, Pigeon, Campbell, Possemato, & Ouimette (2013), examined the prevalence of insomnia and nightmares after six months in eighty combat veterans who met the criteria for sub threshold PTDS. Interviews and self-reports were conducted to measure the severity of insomnia and/or nightmares associated with PTSD (Pigeon et al., 2013). Results indicated that a high PTSD symptom severity level was associated with insomnia; more frequent nightmares; greater alcohol use; and symptoms of depression in the past six months (Pigeon et al., 2013). After six months, veterans were reassessed for whether the insomnia and nightmares frequencies had improved (Pigeon et al., 2013). Out of the entire group of veterans “74% presented with insomnia and 61% endorsed distressing nightmares” (Pigeon et al., 2013, p.549). By the end of the six months, veterans reported a 26% decline in nightmares and a no change in insomnia (Pigeon et al., 2013). The findings demonstrated “a strong association between the presence of sleep disturbance (both insomnia and nightmares) and the severity of both PTSD and depressive symptoms; that the persistence of these symptoms is particularly associated with insomnia; and that insomnia itself does not spontaneously resolve” (Pigeon et al., 2013, p.549). This research established the need for MHNs to implement interventions that will help individuals to cope with the trauma related distress that could contribute drug abuse; suicidal ideation; and insomnia and nightmares. Early interventions for PTSD are necessary to control, reduce or prevent symptoms and the risks they ma...
Arousal disorders are the most common type of parasomnia. These disorders include: confusional arousals, sleepwalking, sleep terrors and nightmares. Experts believe that each is related and share some symptoms. Essentially, they occur because a person is in a mixed state of being both asleep and awake, generally coming from the deepest stage of non-dreaming sleep. The individual is awake enough to act out complex behaviors, but asleep enough not to be aware of or remember them.
“For the disorder first settled in the head, ran its course from thence through the whole of the body, and even where it did not prove mortal, it still left its mark on the extremities; for it settled in the privy parts, the fingers and the toes, and many escaped with the loss of these, some too with that of their eyes.”
Sleep paralysis is a condition that occurs at either the onset or upon awakening of sleep. The medical terms for the two forms of sleep paralysis are hypnogogic and hypnopompic (1). When a person falls asleep, the body secretes hormones that relax certain muscles within the body, causing it to go into paralysis. Doing this prevents the body from acting out a person's dream, which could result in an injury. Sleep paralysis generally runs within one's family or in those who suffer from narcolepsy (2), but there is currently no explanation for why some people get it while others do not.
Witch-trial records, and other early-modern writings on witchcraft, reveal that in various European societies people complained of being physically oppressed at night by witches and other supernatural beings, the victims of these nocturnal assaults describing a similar set of symptoms. Contemporary English authors termed the experience the "mare" or "nightmare." In the twentieth century, it has been identified as a manifestation of "sleep paralysis." Medical studies and surveys of the condition help us make better sense of the historical accounts, while an awareness of the historical evidence illuminates modern reports of sleep paralysis experiences.
Sleep disorders are an underestimated public health concern considering that fifty to seventy million Americans are affected. Technological advances in the field of sleep have facilitated various theories to explain the need for and the purpose of sleep. Scientist have uncovered many types of sleep disorders such as insomnia, sleep apnea, and narcolepsy. Sleep disorders affect men ,women, children, the elderly, and the obese in different ways. Factors such as the number of children and the effects of menopause have been studied to determine their effects on sleep. Various treatments have been utilized ranging from non-pharmacologic to pharmacologic methods. Scientist have pinpointed areas of the brain that are involved in sleep deprivation and hormones that ultimately affect sleep.
