I awoke in darkness, my body utterly unresponsive. At first, I thought I was still dreaming, yet the sensation in the room was different – heavier, charged, undeniably real. A presence loomed. I couldn’t move, couldn’t speak, yet my mind was alert and unusually calm.
Perched on my chest was a small figure, no taller than four feet, thin and entirely black except for the face. Its limbs were unnaturally slender, yet human in proportion. The face… it is hard to describe. Flashing briefly in my mind was the grotesque, demonic visage from The Exorcist: glaring, solid, and impossibly vivid despite the surrounding shadows.
Even as my heartbeat quickened, a strange clarity emerged. I realised I was awake, yet trapped in the residue of a dream. The figure seemed to follow me from sleep into this half-conscious state, yet it did not strike or harm me. Instead, it simply sat, waiting, observing, yet exuding pure malevolence.
Then the thought formed: this is sleep paralysis. Not panic, not disbelief – simple recognition. Almost instantly, the figure’s glare softened; its posture shifted from tense menace to neutral, almost resigned, as if it had been an actor breaking character when the director yells “cut!” Slowly, it rose and walked out of the room. My limbs moved again, and the paralysis ended.
What struck me most was the calmness I retained. Unlike the horror-filled accounts I had read about, I did not feel panic. Recognition, understanding, and analytical observation were my reaction. The experience left me shaken, certainly, but intensely curious: why did awareness exert such immediate influence? Why did acknowledging the phenomenon seem to alter the hallucination so completely?
The Science of Sleep Paralysis
Sleep paralysis is a surprisingly common phenomenon, though estimates of how many people experience it at least once vary widely. Systematic reviews suggest that roughly 8% of the general population report an experience of sleep paralysis in their lifetime. Certain populations, such as university students or individuals with disrupted sleep, show higher prevalence – for instance, some studies find nearly 30% of students have experienced at least one episode.¹ It is also notable that certain sleep disorders, like obstructive sleep apnoea, have been linked by some researchers to increased likelihood of experiencing sleep paralysis – more on this later.
Sleep paralysis occurs when the brain and body fall out of sync during transitions between sleep stages. Normally, during REM sleep (the stage most associated with vivid dreams), the brain induces muscle atonia – a protective paralysis preventing us from physically acting out our dreams. During a typical episode, a person awakens into a semi-conscious state: fully aware of their surroundings, yet completely unable to move or speak.¹
The experience is often accompanied by hypnopompic or hypnagogic hallucinations – dream imagery spilling into wakefulness – such as the sensation of a presence in the room, pressure on the chest, or visual and auditory intrusions.² These hallucinated entities are commonly described as shadowy figures lurking near the bed or doorway; small, humanoid forms perched on the chest – malevolent or threatening presences that inspire immediate panic. In my case, the “demon” I perceived seemed to have followed me out of the dream I was having moments before, dragging elements of that dreamworld into waking reality.
From what I’ve read and observed in other accounts, emotional responses during these episodes are intense: heart rates spike, adrenaline surges, and fear dominates.³ The hallucinations can feel alive, as though they are actively interacting with the sleeper, yet the individual remains helpless to act.
Most first-time experiencers do not recognise the phenomenon as sleep paralysis while it is occurring. This lack of recognition often makes the episode feel like a direct attack by a supernatural entity. Some people report lingering anxiety or dread long after the event has passed.
In contrast, my experience followed a rare pattern: recognition in the moment coupled with analytical curiosity. Instead of succumbing to panic, I observed the figure, noted the dream-to-wake transition, and understood the neurological mechanism at play. Almost as soon as I realised what was happening, the figure’s demeanour shifted – from glaring menace to neutral, almost resigned – and the paralysis began to lift.
I suspect part of why I reacted this way, even as a first-time experiencer, is my long-standing academic interest in the paranormal and related phenomena. Much like people who experience sleep paralysis repeatedly and learn to recognise an “episode” from past encounters, my prior knowledge gave me a head start in understanding and navigating the hallucination. This made me realise how awareness and cognitive appraisal can directly modulate the intensity of sleep paralysis – a concept echoed in both folklore motifs and modern neuroscience.
Folklore and the “Night Demon”
The experience of sleep paralysis is echoed in a host of global traditions. Though the names and forms vary, cultures worldwide have described nocturnal assailants who pin down sleepers, steal breath, or invade dreams. These myths are more than colourful stories – they often encode strategies of resistance that bear a striking similarity to my own experience.
• The Old Hag (Newfoundland & Anglo-American Tradition)
The “Old Hag” is one of the most widely recognised folk interpretations of sleep paralysis, particularly in Newfoundland. Victims report waking to find an old woman sitting heavily on their chest, rendering them immobile and breathless. In many accounts, she appears grotesque, with tangled hair, wrinkled skin, and glaring eyes – similar to contemporary reports of sleep paralysis “intruders.” Unlike in modern clinical language, however, the Old Hag was not seen as a neurological glitch but a supernatural attack.
Ethnographic studies describe communities where sufferers would protect themselves by placing boards, knives, or Bibles near the bed, or by reciting prayers before sleep. Sometimes family members were advised to wake a sufferer by calling their name, an act believed to break the hag’s hold. Folklorist David Hufford, in The Terror That Comes in the Night (1982), noted how recognition of the experience as “the Hag” actually shaped the experience – many Newfoundland subjects had detailed, culturally specific descriptions of her that overlapped with one another, reinforcing a shared supernatural interpretation.³
• The Jinn (Islamic Tradition)
In Islamic belief, jinn are spirit beings made of smokeless fire, with free will to be good or evil, as described in the Qur’an. Across the Middle East, experiences were described as jinn attacks, particularly a subset known as the Qarinah – a female jinn who lies upon the sleeper’s chest to suffocate them. The victim often describes an overwhelming sense of presence in the room, pressure on the chest, and a struggle to breathe – identical to modern sleep paralysis accounts.
Protective rituals against jinn intrusion are heavily rooted in Islamic practice: reciting passages from the Qur’an (especially Ayat al-Kursi, Qur’an 2:255), wearing amulets inscribed with verses, or performing ablution before sleep. Anthropological research notes that the very act of invoking God’s name or reciting Qur’anic verses during paralysis is perceived as a way to repel the entity.⁴
• The Mara (Scandinavian Tradition)
In Norse and later Scandinavian folklore, the mara is a female spirit or witch who “rides” sleeping people, sitting on their chests and causing nightmares and suffocation. The English word “nightmare” derives directly from this figure (mara + “night”). The mara was often described as an evil woman, sometimes a witch or a cursed soul, who slipped through keyholes or cracks in walls to torment sleepers.
Preventative rituals varied: laying iron objects such as scissors under pillows, sleeping with one’s head facing east, or even tying one’s hair in knots before bed to prevent the mara from using it as a “bridle.” In some cases, sleepers were encouraged to confront or name the mara aloud, breaking her influence. These customs, recorded in 17th–19th century Swedish folklore archives, illustrate how the recognition of the entity was a crucial part of defence.⁵
• The Batibat (Philippines)
In Ilocano folklore of the Philippines, the batibat is a large, vengeful female spirit that lives in trees, especially the banyan. If a tree is felled without appeasement rituals, the batibat may follow the lumber to a household, where she attacks sleepers. Victims describe being crushed by the batibat’s immense weight, unable to move or breathe. This folklore persists strongly enough that even today, sudden nocturnal death in the Philippines is sometimes attributed to her, linked to the phenomenon known as bangungot (“nightmare death syndrome”).
To ward off the batibat, sleepers were advised not to lie on their backs, since that posture “invites” her. They might also bite their thumb, wiggle their toes, or call out to household members to break the spirit’s grip.⁶
Note: In these last two examples, we also see another parallel to modern sleep paralysis anecdotes. The preventative measures described against the Mara (sleep with head facing east), or the Batibat (avoid sleeping on your back) suggest an early understanding that sleeping on one’s back exacerbates certain sleep disorders such as sleep apnoea – conditions linked in some research to higher reported incidence of sleep paralysis.
• Kanashibari (Japan)
The Japanese word kanashibari literally means “to be bound in metal” and is used both for magical restraint in folklore and for the paralysis felt during these nocturnal episodes. Early records (Edo period) describe monks and onmyōji (ritual specialists) using spiritual bindings to immobilise adversaries – a magical concept that likely influenced the interpretation of sleep paralysis as being spiritually “tied down.”
Cultural accounts describe sufferers sensing malevolent presences, sometimes ghosts or yōkai, pressing down on them during the night. Ritual responses included chanting Buddhist sutras, invoking protective deities, or sleeping with protective talismans such as ofuda. Modern Japanese even use kanashibari colloquially to describe both supernatural and physiological sleep paralysis, showing how embedded the motif remains.⁷
• Naming the Demon (Christian Motif)
Christian demonology preserves a motif that resonates strongly with these traditions: the belief that speaking the demon’s name grants power over it. From the Gospels (where Jesus drives out demons by name) to medieval exorcism rites, identification was the first step toward banishment. Such attacks framed through Christian belief often involved demonic oppression – “night terrors” were blamed on demons attempting to suffocate or corrupt the soul. Prayer, the sign of the cross, or invoking Christ’s name (“In the name of Jesus”) were prescribed defences.⁸
What is particularly striking is the similarity between folkloric countermeasures and modern coping strategies. In all of these examples, the key similarity in combatting such demonic attacks lies in the act of identifying, recognising and acknowledging the threat by name.
It would appear that the proponents of these ancient beliefs were onto something – the power of these old methods lies not in the ritual itself, but in this act of acknowledgment. The psychological mechanism may be simple: recognition restores a sense of agency, reducing panic and often terminating the episode. The same principle has also been claimed to underpin so-called “lucid dreaming”, where it is believed that the dreamer’s awareness of the dream state allows them to consciously influence its unfolding.
Conclusion: Recognition as Resistance
My own experience – where realisation disarmed the perceived threat – echoes across centuries of myth and belief. The figures and rituals may vary, yet the core remains remarkably consistent: acknowledgement restores agency to the “victim”.
What folklore framed as ‘naming the demon,’ contemporary psychology might describe as cognitive reappraisal – the deliberate reframing of a perceived threat to restore agency. In both cases, the shift into metacognitive awareness interrupts the fear–paralysis loop. Whether the words are ritual or clinical, the underlying mechanism is the same: recognition transforms the experience from an assault into an event you can navigate.
Modern science frames this in psychological terms: recognising sleep paralysis for what it is reduces fear, interrupts the panic loop, and may even end the episode. Folklore encoded the same insight in ritual and myth. Both point to a fundamental truth – that naming the demon, whether literally or metaphorically, gives us the power to withstand it.
The night I met a “demon”, I did not banish it with prayers or charms. I defeated it by speaking its true name – sleep paralysis. And that recognition was enough to free me from its grasp.
