• 'It's a very profound and frightening experience,' says Dr Chris French, a psychologist at Goldsmiths who specialises in the psychology of paranormal experiences and is collecting data on sleep paralysis. ...
• Sleep paralysis usually happens when someone is just entering or leaving sleep, and lasts from a few seconds to a couple of minutes. Most research has linked it with REM, or rapid eye movement, sleep which indicates dreaming. When the body and brain enter REM sleep, the muscles relax and the brain blocks signals that would normally allow the limbs to move, so preventing the body from acting out its dreams. One suggestion for the cause of sleep paralysis is that the firewall between sleeping and wakefulness temporarily drops, so that some sleep phenomena, of which paralysis is one, breaks into wakefulness. ...

• Narcolepsy is a sleep disorder marked by recurring, uncontrollable episodes of sleep during normal waking hours, as well as by sudden episodes of muscle weakness (cataplexy), sleep paralysis, and hallucinations.
• These episodes resemble the muscle relaxation that occurs during REM sleep and, to a lesser degree, the experience of being "weak with laughter. ...
• This experience, called sleep paralysis, can be terrifying. The touch of another person may relieve the paralysis. Otherwise, the paralysis disappears on its own after several minutes.
• Sleep paralysis and hallucinations occasionally occur in otherwise healthy adults. If the diagnosis is uncertain, electroencephalography (EEG), which records the brain's electrical activity (see Section 6, Chapter 77), is performed, usually in a sleep laboratory. If a person has narcolepsy, EEG typically shows that REM-type sleep activity occurs as the person falls asleep, rather than later in the sleep cycle as it normally does. ...

• ALIEN ABDUCTION? JUNK SCIENCE CALLS IT SLEEP PARALYSIS.
• This is the way the New York Times should have headlined their July 6 science section piece on the poorly understood phenomenon of sleep paralysis. Unfortunately, however, the headline read "Alien Abduction? Science Calls It Sleep Paralysis" my emphasis , suggesting to the world that the UFO abduction phenomenon has at last been successfully explained away. ...
• " What data were amassed and studied to support a headline proclaiming that abductions have now been explained as nothing more than cases of sleep paralysis? A careful look at the existing data is enlightening. ... So where do nighttime sleep paralysis experiences come into the data pool of these crucially important first decades of abduction research? Nowhere. ...
• The Times writers therefore had no reason not to give knee-jerk support to the idea that sleep paralysis is the source of the UFO abduction phenomenon. ...
• In order to accept the sleep paralysis explanation, any scientist, journalist or lay person must first suppress any contradictory data. Thus, the Times article suppressed the fact that for the first two decades of abduction research, all of the central cases took place with the abductees fully awake and functioning, and none involved bedroom paralysis. ...
• Having established the irrelevancy of sleep paralysis as the cause of the UFO abduction phenomenon, let us take up a more realistic issue. In later decades, when bedroom abduction cases began to be reported, might some of these involve sleep paralysis and nothing more? Of course. The possibility always exists that some sleep paralysis experiences might have been misinterpreted by the individuals reporting them as UFO abductions, particularly by susceptible people who have been devouring books on UFOs. ...

• Kanashibari, or sleep paralysis, usually happens when the sleeper is either entering or coming out of REM sleep. When we enter REM sleep, the brain and body "disconnect", and the body is effectively paralysed so that we don't act out our dreams. Sleep paralysis occurs when the body's transition to or from REM sleep is "out of time" with that of the brain, that is, the body is asleep while the brain is either awake or half-awake. ... Often, the paralysis is accompanied by auditory, visual and tactile hallucinations. ...

Add to that that this is a time when young people are experiencing the pressure of entrance examinations, and when sleep patterns are often interrupted due to long hours of study. ...

• Have you ever wondered how people sleep walk?   Well normally, we don't act out our dreams because a mechanism in our nervous system paralyzes our body when we're dreaming.   But if for some reason that mechanism doesn't work on cue, then if a person dreams, that person will act out that dream and sleep walk.
•   It explains the direct causes of sleep paralysis, hyponogogic hallucination, and lucid dreaming.   Sleep paralysis is when you are unable to move after waking up or before going to sleep.   Hypnogogic hallucination is when you hallucinate after waking up or before going to sleep. ...

• Do you work shifts and find yourself unable to get a normal sleep pattern going?.
• These and many other unusual happenings all fall in the domain of the sleep researcher. While the concept of watching someone sleep may not be your cup of tea, there are many researchers and medical personnel around the world who do just that.
• Sleep research falls into 2 very distinct fields - the pure science and the sleep disorder field.
• Many scientists are still looking to solve some fundamental issues about sleeping - such as why do we sleep? (Apart from just making sure we don't fall asleep the next day!).
• Sleep Paralysis.
• Research in this area ranges from investigating the basic neurological mechanisms such as the paralysis that occurs during REM or dreaming sleep. The importance of the paralysis may be to prevent us acting out our dreams and certainly creates the feeling of an inability to move or run away when we are faced by nightmares. If this paralysis doesn't stop on waking, people may experience sleep paralysis and an inability to move when they wake up as in the scenario described above.
• In elderly men, particularly, the normal paralysis during REM sleep may not occur due to aging changes. ...
• These and many other variables increase and decrease at various times during the day and night and determine when we need to sleep and be most alert. Simply changing our desired bedtime such as during shift work or when traveling across time zones does not guarantee that our body will be ready to sleep when we want it to. ...
• We all know that if we are sick or sore that our sleep tends to be interrupted. The scientific literature however, cannot tell you at present how much pain will interrupt your sleep, how it will change the character of your sleep and what medication is the best to resolve that problem. So researchers spend nights letting people fall asleep and then hurting them slightly to see what the impact on their sleep is. ...

• Narcolepsy is a chronic neurological disorder that is the second leading cause of excessive daytime sleepiness after obstructive sleep apnea. ...
• Narcolepsy impairs the ability of the central nervous system to regulate sleep. ... Hypocretin activates arousal and regulates sleep.
• In addition to excessive daytime sleepiness and sudden episodes of falling asleep, other symptoms typically associated with narcolepsy are: cataplexy (short-lived intermittent muscle weakness), hypnogogic hallucinations (hallucinations while falling asleep or waking), sleep paralysis (paralysis while falling asleep or waking), and automatic behavior. ...
• The Sleep Foundation’s Living with Narcolepsy provides further explanation about the symptoms of narcolepsy: .
• Sleep Paralysis – being unable to talk or move for a brief period when falling asleep or waking up. Many persons with narcolepsy suffer short-lasting partial or complete sleep paralysis. ...
• People without narcolepsy may experience hypnagogic hallucinations and sleep paralysis as well. ...
• Narcolepsy can be diagnosed through the presence of symptoms, although some of the symptoms are associated with other sleep disorders and depression. A nocturnal polysomnogram and a multiple sleep latency test (MSLT), performed at a sleep disorders clinic, can provide conclusive diagnosis and rule out other possible causes of excessive daytime sleepiness. It is important to see your doctor or a sleep specialist if you suspect you have narcolepsy.
• Doctors often prescribe stimulants to improve alertness and anti-depressants to control cataplexy, hypnagogic hallucinations and sleep paralysis. For narcolepsy, some sleep specialists also recommend several short daily naps to combat excessive sleepiness and sleep attacks. ...

• Whether Sp is an occasional or frequent sleep experience, overcoming the tremendous and overwhelming fear associated with atonia ( paralysis ) may be a real obstacle to using SP as a 'launching pad'to LD. ... Since repeated occurrences are the norm within a relatively short, nighttime period, changing sleeping positions ( for example, from laying on one's back to a belly down or sideways posture ) often allows the SP experiencer to return to normal REM sleep, to less conscious REM sleep.
• I have been an SP (and LD) experiencer since my early teens and I must say that in time, one learns to overcome most if not all of the anxiety associated with the paralysis and is able to enter a new dimension of dream experience - richer and more creative than that of the average dreamer. ...

• Isolated Sleep Paralysis (SP) occurs at least once in a lifetime in 40-50% of normal subjects, while as a chronic complaint it is an uncommon and scarcely known disorder. A series of messages written by subjects who experienced at least one episode of SP, containing more or less detailed descriptions of this disorder, were collected from the Sleep Web site of the University of California in Los Angeles between January 1996 and July 1998. Two hundred and sixty-four messages fulfilling the International Classification of Sleep Disorders (ICSD) (Thorpy, 1990) minimal criteria for SP were analyzed. ...
• Current Claim: Isolated Sleep Paralysis may occur with a wide spectrum of severity, including a recurrent form which closely resembles the ion-channel pathologies, and it is often accompanied by stereotyped subjective experiences which suggest an activation of limbic system structures. ...
• Sleep Paralysis (SP) and hallucinations in the wake-sleep (hypnagogic) or sleep-wake (hypnopompic) transition can occur separately or in association, and they seem to share a common neurophysiopathologic substrate, as shown by polysomnographic registrations of such events occasionally captured in a laboratory. In either case, clinical and electrophysiologic assessment evidences a mixed pattern of REM sleep phase and wakefulness (Takeuchi et al. ... REM sleep is a brain-activated state, characterized by a desynchronized electroencephalographic activity resembling that of wakefulness. ... REM sleep phasic activities are supposed to underlie the hallucinoid imagery of dreams. ... In spite of this high brain activation, REM sleep differs from wakefulness because of muscular atonia, with abolished H-reflex, caused by inhibitory postsynaptic potentials in spinal motoneurons. Furthermore, late cerebral responses to somatosensory stimulation (P100, P200, P300) disappear during REM sleep (Goff et al. ... SP differs from normal REM sleep since there is not such blocking of exteroceptive stimulation, and waking consciousness is largely retained (Hishikawa and Kaneko, 1965). ...

• We followed the minimal criteria of the ICSD (1990): A (a complaint of inability to move the trunk or limbs at sleep onset or upon awakening) + B (presence of brief episodes of partial or complete skeletal muscle paralysis) + E (not associated with other medical or psychiatric disorders); the latter criterion has been applied as far as possible according to the available data. On the other hand, all participants reported a substantially stereotyped symptomatology (a disorder arising at sleep onset or on awakening, characterized by skeletal muscle paralysis associated with a high level of alertness, with sparing of ocular movements and a cessation that occurs in seconds or minutes when spontaneous, or suddenly when the patient is touched by a relative) that seems to warrant a sufficient diagnostic certainty. ...

Sleep tends to occur during monotonous conditions conducive to normal sleep but may also occur during hazardous circumstances (eg, while driving). ... Total daily sleep time usually does not increase despite the frequent sleep episodes. Onset of REM sleep is almost instantaneous. This pattern differs from normal sleep, in which NREM sleep usually lasts about 60 to 90 min, preceding REM sleep. Nighttime sleep may be unsatisfying and interrupted by vivid, frightening dreams.
