[size=48]A waking nightmare: The enigma of sleep paralysis[/size]

Published Friday 20 April 2018

You wake up in the middle of the night, convinced that an evil figure is lying in wait. You attempt to move, but your body just will not budge. You try to scream, but nothing comes out. The monster draws closer. It may sound like a horror movie scene, but this is the real deal — you're experiencing sleep paralysis.

Sleep paralysis is like a waking nightmare, and the underlying causes for this condition remain unclear.[/size]
This terrifying and mysterious sleep disorder, or parasomnia, has been experienced by people possibly since the dawn of humankind.
And, it may have given rise to numerous ghost stories and mysterious accounts involving "things that go bump in the night."
This most unsettling experience was first clearly documented in a medical treatise in the 17th century, by Dutch physician Isbrand Van Diembroeck, who wrote about the case of a woman "50 years of age, in good plight [health], strong," yet who complained of mysterious experiences at night.
"[W]hen she was composing her self to sleep," explains Van Diembroeck, "sometimes she believed the devil lay upon her and held her down, sometimes that she was [choked] by a great dog or thief lying upon her breast, so that she could hardly speak or [breathe], and when she endeavored to throw off the [burden], she was not able to stir her members."
What the woman in Van Dimbroeck's account likely experienced was a condition that has come to be known as "sleep paralysis."
Researchers define it as "a common, generally benign, parasomnia characterized by brief episodes of inability to move or speak combined with waking consciousness."

[size=38]Sleep paralysis and hallucinations[/size]

The reason why sleep paralysis is so scary is not just because you will suddenly become alert but realize that you are, in fact, unable to move a muscle or utter a sound, but also because this experience is often — as in the case above — accompanied by terrifying hallucinations.
These, as specialized literature has now ascertained, typically fall into three distinct categories:
[/size][list="box-sizing: border-box; margin: -10px 0px 25px 7px; counter-reset: a 0; padding-right: 0px; padding-left: 20px; list-style: disc outside;"]
[*]a sensed presence, or intruder hallucinations, in which the person feels the presence of an evil, threatening individual
[*]incubus hallucinations, in which the person might feel someone or something pressing down uncomfortably, even painfully, on their chest or abdomen, or trying to choke them
[*]vestibular-motor hallucinations, during which the individual thinks that they are floating, flying, or moving — these may also sometimes include out-of-body experiences, in which a person thinks that their spirit or mind has left their body and is moving and observing events from above
[/list]
[size]
Among the types of dreamlike hallucinations listed above, the first type — a sensed presence — is one of the most commonly experienced by people with sleep paralysis.
As for the time of sleep at which sleep paralysis — with or without hallucinations — normally takes place, again, there is no single answer.
According to a study that was published in the Journal of Sleep Research, sleep paralysis typically happens soon after falling asleep (or hypnagogic episodes), at some point during the course of sleep (or hypnomesic episodes), or a little before the person's usual time of awakening (or hypnopompic episodes).
The authors of that study note that the most common instances of sleep paralysis are hypnomesic, and that they usually take place after 1–3 hours from falling asleep.

'A strange, shadowy man'

In fact, these visions and sensations can seem so realistic to many people that they may think that they are having a paranormal experience, or even being subjected to strange tests and rituals.

The most common hallucination linked to sleep paralysis is the 'sensed presence' of a sinister figure.[/size]
"Witness accounts" of such hallucinations can be truly unsettling, and a number of long-time experients — such as Louid Proud in his book Dark Intrusions — have offered detailed accounts of years of uncanny nightly encounters.
One person who told me about his nightmarish hallucinations said he felt as if "someone knelt on [his] chest so that it [felt] as if [he was] being choked out."
Another person spoke of a night-time assailant that takes pleasure in tormenting her in myriad ways.
[/size]

"When [sleep paralysis] strikes, I get both visual and auditory hallucinations, which most often involve a strange, shadowy man coming up my stairs and into my bedroom. Occasionally, he'll prod or tickle me."

[size]
Often, she told me, this sinister figure even "co-opts" her partner in his mischief.
"Sometimes," she says, "I'll even hallucinate my partner lying next to me and laughing maliciously at me, or siding with the shadowy figure in annoying me. This is very frustrating, since all I want him to do is help me!"
Given the intensity of these hallucinatory experiences, it may come as no surprise that researchers have repeatedly argued that hallucinations linked with sleep paralysis can be held responsible for many reports of magical events, sightings of ghouls and demons, and alien abductions.

Some happy exceptions

Although usually people with sleep paralysis report experiencing terrifying hallucinations, a happy few actually point to a state of bliss that makes them look forward to these episodes.
A study that was conducted by James Allan Cheyne, from the University of Waterloo in Ontario, Canada, suggests that the people who most often describe experiencing positive feelings and sensations during an episode of sleep paralysis are those who are prone to vestibular-motor hallucinations.
[/size]

"These hallucinations were found to involve feelings of floating and [out-of-body experiences], which are associated with feelings of bliss rather than fear."
James Allan Cheyne

[size]
"In contrast to the other-oriented nature of the Intruder and Incubus hallucinations," he adds, "these experiences are very much focused on the experient's own person."
Sometimes, Cheyne continues, feelings of bliss during sleep paralysis are derived from pleasant erotic sensations that arise from vestibular-motor hallucinations.

[size=38]What is the underlying mechanism?[/size]

So, what happens in the body during an episode of sleep paralysis? Essentially, during the dream phase of sleep — known as the rapid eye movement (REM) phase — our skeletal muscles are paralyzed.

The reasons behind this are not fully understood, though researchers have been making progress in uncovering the mechanisms attached to this process.

One popular theory posits that this temporary state of paralysis is meant to prevent us from hurting ourselves, perhaps in automatic response to some violent dream.
During sleep paralysis, paradoxically, our brains — or parts of our brains — become awake and conscious, but the rest of the body is still immobilized.
At the same time, during sleep paralysis, many people experience dream visions and sensations as though they were real — hence the hallucinations — and the fact that they are, in fact, partly awake and conscious blurs the line between reality and dreams.

[size=38]Who is at risk of sleep paralysis?[/size]

Sleep paralysis is more common than we may think. A 2016 study declares that it is "surprisingly common," but that "determining accurate prevalence rates is complicated" because researchers and study participants alike have different understandings of what counts as sleep paralysis.

[size][size]
Although a fair amount of research has been conducted in this respect, it remais unclear as to who is most at risk of sleep paralysis.[/size]
A recent review of the available data, however, suggests that 7.6 percent of the population have experienced at least one episode throughout their lives.
That said, the numbers may be even higher.
What causes sleep paralysis, and what the main risks are for experiencing such an episode, remain largely mysterious.
Sleep paralysis is a common symptom of the neurological disorder "narcolepsy," which is characterized by uncontrollable sleepiness throughout the waking day.

But many people who experience sleep paralysis do so independently of neurological conditions. And, to distinguish between narcolepsy-related episodes and independently occurring sleep paralysis, specialists usually refer to the latter as "isolated sleep paralysis."
Recurrent isolated sleep paralysis often starts in adolescence, and around 28.3 percent of students apparently experience it.
Moreover, people with poor "sleep hygiene" — for instance, those who sleep too much or too little — may also be more likely to experience sleep paralysis. The authors of a systematic reviewpublished in Sleep Medicine Reviews note:
[/size]

"Specifically, excessively short (fewer than 6 hours) or long (over 9 hours) sleep duration and napping, especially long naps (over 2 hours), were associated with increased odds of sleep paralysis."

[size]
"Long self-reported sleep latency [how long it takes to fall asleep] (over 30 minutes) and difficulty initiating sleep were related to an increased likelihood of reporting sleep paralysis," they add.

Are mental health issues to blame?

Given the frightening nature of the most of the hallucinations associated with sleep paralysis, many have wondered whether individuals experiencing mental health issues — such as depression or anxiety — are more susceptible to these experiences.
The results of existing research, however, are mixed. Some have argued that individuals who have experienced abuse in early life — whether or not they remember it — may be more exposed to sleep paralysis.
According to the study that was published in Sleep Medicine Reviews, "Levels of waking state dissociative experiences, involving depersonalisation, derealisation, and amnesia, were found to be related to both sleep paralysis frequency and the frequency/intensity of all three hallucination types."
But links to other neurological and psychiatric disorders are more uncertain.
The authors of a study that was published in the journal Consciousness and Cognition note that previous research has tried to make a case that bipolar disorder, post-traumatic stress disorder, depression, panic disorder, and generalized anxiety disorder — to name but a few — may play a role in sleep paralysis.
However, they report that their analysis of the available data has revealed "no general relationship between [isolated sleep paralysis] and major psychopathology."
Instead, they decided to focus on the most common "symptom" of sleep paralysis — that is, sensed presence hallucinations that induce a feeling of fear — and explained that there may be a link between it and what they call "passive social imagery."
Passive social imagery refers to the experience of individuals who are prone to being more socially anxious, and to imagining themselves in embarrassing or distressing social situations as the passive victim on the receiving end of abuse.
These individuals, the researchers suggest, appear to be more at risk of experiencing distress due to sensed presence hallucinations.

[size=38]What can you do to prevent it?[/size]

Prevention and coping strategies for sleep paralysis are, unfortunately, mostly anecdotal, but there are some methods that seem to have been repeatedly validated by many individuals who say that they — usually or often — work for them.
These include:
[/size]

• trying not to fall asleep on on your back, since studies have associated episodes of sleep paralysis with lying on one's back when going to sleep
  
• trying to ensure, on a regular basis, that your sleep will not be disrupted, since repeatedly waking up during the night has been flagged up as a potential risk factor
  
• avoiding overuse of stimulants, such as tobacco and alcohol — coffee, surprisingly, has not been deemed risky in this context — though the evidence that these affect the chances of experiencing sleep paralysis is mixed
  
• learning meditation and muscle relaxation techniques may help you to better cope with the experience
  
• persisting in the attempt "to move extremities," such as fingers or toes, during sleep paralysis also seems to help disrupt the experience
  

[size]
Finally, if you regularly experience sleep paralysis with "sensed presence" and you think that this may be related to other experiences of anxiety in your day-to-day life, then it may be worth considering cognitive behavioral therapy.
According to the authors of the Consciousness and Cognition study, there is a distinct "possibility that frightening [isolated sleep paralysis] sensed presence experiences [...] may contribute to maintenance of an individual's negative social imagery biases."
If that is the case, they argue, "cognitive behavioral treatment of [these] experiences could help to alleviate the more general social imagery dysfunction," which may improve the overall situation.
