Sleep paralysis is a state during which an individual is conscious yet unable to move or speak. It occurs when an individual wakes up during the dream phase of sleep, also known as REM sleep, and the brain turns off signals to the body to prevent it from acting out dreams. Sleep paralysis is often accompanied by hallucinations, which can be threatening in nature due to the individual's state of paralysis and vulnerability. In various cultures, sleep paralysis has been associated with supernatural entities, such as ghosts, demons, or, in the case of Newfoundland, the Old Hag. This phenomenon has led to the condition being referred to as the old hag syndrome.

Sleep paralysis is a state of full-body paralysis during sleep
During sleep paralysis, it is common for individuals to experience hallucinations, which can be visual, auditory, or tactile. These hallucinations often involve a sense of threat and the presence of a menacing figure, such as an old lady or a witch, that the individual feels is in the room with them. This phenomenon is sometimes referred to as "the old hag syndrome", especially in places like Newfoundland, Canada. The experience can be terrifying, with individuals reporting feelings of intense anxiety and fear.
The old lady or witch figure seen during sleep paralysis may be related to cultural beliefs and folklore. For example, in Brazilian folklore, there is a figure called the "pisadeira", an old woman who lies in wait on roofs and walks on the chests of people who sleep on their backs with full stomachs. In Japan, sleep paralysis is called "kanashibari", which is rooted in Buddhism and associated with the magical powers of Buddhist monks who could paralyze others. These cultural influences may shape the specific content of hallucinations experienced during sleep paralysis.
While the exact causes of sleep paralysis are not fully understood, there are some strategies to reduce the likelihood of experiencing it. Improving sleep hygiene by establishing a consistent and calming sleep routine, optimizing the sleep environment, reducing substance use, and curbing electronic device usage before bed can help stabilize sleep cycles and reduce the occurrence of sleep paralysis. Additionally, addressing sleep disorders, managing stress, and seeking support for associated mental health conditions can also potentially reduce the frequency of episodes.
It is important to note that sleep paralysis is typically not considered dangerous, and it is classified as a benign condition. However, for some individuals, the experience can be emotionally distressing and disruptive to their daily lives. If frequent episodes or anxiety related to sleep paralysis are occurring, it is recommended to consult a healthcare provider for guidance and support.

It is often accompanied by hallucinations, which may be visual or auditory
Sleep paralysis is a state, during waking up or falling asleep, in which a person is conscious but unable to move or speak. Episodes generally last no more than a few minutes and can reoccur multiple times or occur as a single episode. Sleep paralysis is often accompanied by hallucinations, which may be visual or auditory.
During an episode, people may experience vivid, terrifying hallucinations, imagining they see or hear something, or that someone or something is in the room with them. These hallucinations are referred to as sleep paralysis demons. People often describe seeing someone standing in the corner, lurking near the bed, or approaching slowly. They may also experience a sense of being watched, or see shadowy, human-like figures in the room, often interpreted as demons, ghosts, or intruders due to their menacing presence and the intense fear they provoke.
In some cultures, sleep paralysis is associated with folklore and mythology. In Newfoundland, Canada, it is referred to as the "Old Hag", and victims are said to be "hag-ridden" upon awakening. In Brazil, an old woman called a "pisadeira" is said to lie in wait on roofs and walk on the chests of people who sleep on their backs with a full stomach. In Japan, sleep paralysis is called "kanashibari", a term rooted in Buddhism, as it was believed that Buddhist monks could use magic to paralyze others.
The intruder and incubus hallucinations are highly correlated with one another and are moderately correlated with the third type of hallucination, vestibular-motor disorientation, or out-of-body experiences. A hyper-vigilant state created in the midbrain may further contribute to hallucinations. When individuals wake up paralyzed and feel vulnerable to attack, the threat response can be intensified, explaining why such visions during sleep paralysis are so vivid.

Sleep paralysis is also called the old hag syndrome, with victims said to be hag-ridden
Sleep paralysis is a state of full-body paralysis that occurs when an individual is conscious and awake, but their body is still in a sleeping state. During an episode, the person may hallucinate, often resulting in fear. Sleep paralysis is also called "the old hag syndrome", with victims said to be "hag-ridden" upon awakening. This term is used because people often report seeing an old hag or witch during their episodes. In fact, in Newfoundland, Canada, sleep paralysis is referred to as the "Old Hag". Victims report being conscious but unable to speak or move, and they often report a person or animal sitting on their chest.
There are several reasons why people may see an old lady or hag during sleep paralysis. One theory suggests that it is due to a brief myoclonic spike in brain activity, which induces a floating sensation and can lead to vivid hallucinations. The feeling of vulnerability during sleep paralysis may also contribute to these hallucinations, as the threat response is intensified, making the visions more vivid and terrifying. Additionally, sleep paralysis is linked to sleep disorders and mental health conditions, such as post-traumatic stress disorder (PTSD) and anxiety disorders, which may influence the content of hallucinations.
Cultural influences may also play a role in the perception of seeing an old hag during sleep paralysis. For example, in Brazilian folklore, there is a figure called a "pisadeira", an old woman who lies in wait on roofs and walks on the chests of people who sleep on their backs with full stomachs. Similarly, in Japan, sleep paralysis is called "kanashibari", which is rooted in Buddhism and associated with the belief that Buddhist monks could use magic to paralyze others. These cultural beliefs and stories may shape how individuals interpret their sleep paralysis experiences, including the perception of an old hag or witch.
While the exact causes of sleep paralysis are not fully understood, it is believed to be linked to a dysfunction in REM sleep and can be triggered by sleep deprivation, psychological stress, or abnormal sleep cycles. It is important to note that sleep paralysis is generally considered a benign condition and is not typically dangerous. However, for some individuals, it can cause emotional distress and anxiety. If episodes become frequent or disruptive, it is recommended to seek advice from a healthcare provider.

The old hag is a common figure in folklore, appearing in films, plays, and crafts in Newfoundland
Sleep paralysis is a state during which an individual is conscious yet unable to move or speak. It occurs when there is a disruption in the transition between wakefulness and REM sleep. During an episode, the person may hallucinate, often resulting in fear.
In Newfoundland, sleep paralysis is referred to as "The Old Hag", a prominent figure in local folklore. The Old Hag is described as a malevolent entity that visits people during sleep paralysis, taking the form of an old woman with wrinkled skin, wild hair, and a twisted grin. She is said to sit on the chest of her victims, making it difficult for them to breathe, and sometimes whispers threats or curses into their ears. The belief in the Old Hag is deeply ingrained in the culture and passed down through generations, with many attributing their sleep paralysis episodes to this spirit.
The Old Hag is well-known enough in Newfoundland to have become a pop culture figure, appearing in films and plays, as well as crafted objects. The legend of the Old Hag has its roots in centuries-old beliefs about witchcraft and the occult, and it continues to fascinate and terrify people, with some seeking cures or preventions for the phenomenon.
While the Old Hag is unique to Newfoundland, similar experiences and stories have been reported in various cultures worldwide. Psychologists and neuroscientists now understand sleep paralysis as a natural occurrence, likely caused by disruptions in sleep patterns. However, the folklore surrounding the Old Hag has persisted, providing a way for people to make sense of the terrifying and unexplained phenomenon of sleep paralysis.

Sleep paralysis may be triggered by sleep deprivation, psychological stress, or abnormal sleep cycles
Sleep paralysis is a frightening but harmless phenomenon where a person becomes conscious but is unable to move their body or speak. It can occur during the transition between sleep and wakefulness. During an episode, the person may hallucinate, often seeing menacing figures or feeling vulnerable to attack.
Abnormal sleep cycles, including erratic sleep schedules and irregular sleep patterns, can also trigger sleep paralysis. This is particularly common among shift workers, who often experience disruptions in their sleep schedules. Additionally, sleeping in the supine position (on the back) has been found to be an instigator of sleep paralysis. This sleeping position can cause the soft palate to collapse and obstruct the airway, potentially triggering an episode.
While the exact cause of sleep paralysis is not fully understood, it is believed to be associated with a dysfunction in the REM sleep stage. During REM sleep, the eyes move rapidly, and vivid dreaming occurs, while the muscles of the body are relaxed to prevent acting out dreams. Sleep paralysis occurs when an individual wakes up suddenly from REM sleep, regaining awareness while the muscles remain relaxed. This results in a temporary paralysis, and the mental imagery of REM sleep can persist, leading to vivid hallucinations.
The experience of seeing an old lady during sleep paralysis is commonly referred to as "the old hag syndrome." It is intriguing that many people report seeing a similar figure, which may be related to the neurological aspects of sleep paralysis. The cerebellum, which coordinates body movement, may experience a brief spike in brain activity, inducing a floating sensation. Additionally, the threat-activated vigilance system in the brain may be activated, intensifying the sense of vulnerability and contributing to the vividness of the hallucinations.
