Sleep paralysis (SP) is a dissociative experience that happens mostly when you wake up. Changes in motor, perceptual, affective, and cognitive functions, such as inability to make voluntary movements, visual hallucinations, chest pressure, delusions about a frightening presence, and, in some cases, fear of approaching death, are all symptoms of SP. SP is most commonly connected with sleeping in the supine position, however it is considered a disorder (parasomnia) when it is recurrent and/or coupled with emotional stress. Surprisingly, different people have interpreted SP in different ways throughout human history. Canadian Eskimos, for example, ascribe SP to shaman spells that impair movement and cause hallucinations of a shapeless presence. SP is said to be caused by a vengeful spirit who suffocates his enemies while sleeping in Japanese folklore. In Nigerian culture, a female demon attacks and paralyzes people while they are dreaming. The report of SP is a current version of SP “Alien abductions” are characterized by incapacity to move upon waking, as well as visual hallucinations of aliens. Overall, SP is a good illustration of how different cultural contexts can influence how a biological event is viewed and molded. In order to go more into the ethnopsychology of SP, we present the following review “The character “Pisadeira” is a character from Brazilian folklore who originated in the country's southeast but may also be found in other parts of the country under different names. Pisadeira is a crone with long fingernails that hides on roofs at night and tramples on the chests of those who sleep with their belly up. Many anthropological studies mention this legend, but we couldn't find a complete reference on the Pisadeira from the standpoint of sleep research. This is where we hope to fill the void. The Pisadeira traditional tale is presented after a study of the neuropsychological characteristics of SP. Finally, we review the many historical and artistic expressions of SP in other cultures, highlighting similarities and distinctions with the Pisadeira.

What triggers sleep paralysis?
Sleep deprivation, or a lack of sleep, is one of the leading causes of sleep paralysis. Changing your sleep routine, sleeping on your back, using certain drugs, stress, and other sleep-related issues like narcolepsy could all play a role.
Does sleep paralysis mean anything?
In most situations, sleep paralysis is merely a warning that your body is not going smoothly through the stages of sleep, according to sleep researchers. Sleep paralysis is rarely linked to underlying psychological issues.
Why do I keep having sleep paralysis in my dreams?
During your sleep cycle's transition phases, you may experience sleep paralysis. This implies it can happen right before you fall asleep or right after you wake up. Simply put, your mind is transitioning to dreaming faster than your body. The experience is short-lived, lasting barely a few seconds to a minute.
What is Sexomnia?
Sexsomnia is an uncommon sleep disorder in which an individual engages in sexual activity while sleeping. They will have no memory of what happened during the act or after they wake up.
- What is sexsomnia? We examine what sleep science has to say about this uncommon condition.
- the causes of sexsomnia and the effects it has on the individual and others around them
- sexsomnia and the law: case studies and the challenges it poses in legal proceedings
- how lifestyle modifications and addressing underlying health issues can effectively treat sexsomnia
Has anyone died sleep paralysis?
– While sleep paralysis might be a frightening experience, the truth is that there is nothing to be concerned about. It hasn't caused any physical harm to the body, and no clinical deaths have been reported to date.
What do people see during sleep paralysis?
Imagine being startled awake in the middle of the night by an eerie apparition with blood spilling from its fangs. You try to shout but are unable to. You are unable to move even a single muscle! If this sounds familiar, you've probably had a case of sleep paralysis, which causes you to be unable to move or talk when you fall asleep or wake up, and is frequently accompanied by hallucinations. At least once, one out of every five persons has had sleep paralysis. Despite its frequency, it has remained mostly unknown. For millennia, people have attributed these hallucinations to black magic, mythical monsters, and even paranormal activity in societies all across the world. Despite the fact that scientists have invalidated such hypotheses, cultural beliefs endure. Indeed, research undertaken by my colleagues and me over the course of a decade in six nations reveals that ideas about sleep paralysis can drastically affect the physical and psychological experience, indicating a fascinating type of mind-body interaction.
What appears to be a basic brain defect at the border between wakefulness and rapid eye movement (REM) sleep causes sleep paralysis. You get vivid, lifelike dreams while in REM. Your brain devises a brilliant way to prevent you from carrying on these realistic dreams (and injuring yourself!). It momentarily paralyzes your entire body. Your brain does, in fact, have a “switch” (a group of neurochemicals) that allows you to alternate between sleep and waking. However, there are instances when the “switch” fails, and your brain wakes up while your body is still under the “spell” of REM paralysis, trapping you in a paradoxical condition of awake and REM sleep. The vivid dreams of REM “spill over” into waking consciousness during sleep paralysis, like a dream coming alive before your eyesfanged figures and all.
These hallucinations, which frequently involve seeing and sensing phantom bedroom intruders, are interpreted differently in different parts of the world. Sleep paralysis is commonly supposed to be caused by a jinn (“genie”), a mythological monster who terrorizes and occasionally murders its victims in Egypt. Sleep paralysis is sometimes interpreted in Italy as an attack by the so-called Pandafeche, a wicked witch or terrifying huge cat. Indigenous people in South Africa think segatelelo (black magic) is to blame for the state, which involves scary dwarflike monsters known as tokoloshe, and strange spirit-like entities known as karabasan in Turkey. The Danes, on the other hand, provide a less imaginative explanation: sleep paralysis is generally attributed to physiological risk factors such as stress.
These theories, both scientific and sensationalist, have the potential to change people's perceptions of sleep paralysis. When we compared the dread of the occurrence in Egypt and Denmark, we discovered that Egyptians are far more afraid than Danes. In fact, more than half of Egyptians who suffered from sleep paralysis believed the ailment was fatal. Egyptians also thought the incidents lasted longer, and they happened three times more frequently for this population. Egyptians' beliefs regarding sleep paralysis seems to have had a significant impact on their experience. Those who blamed supernatural forces were more terrified about the encounter and were paralyzed for longer. A pattern was beginning to emerge. Sleep paralysis had evolved from a simple “brain glitch” to a chronic, long-lasting, and potentially fatal supernatural experience when combined with specific beliefs.
It was unclear whether the findings could be reproduced. The origin of sleep paralysis is also a topic of intense cultural debate among Italians. More than a third of people from the Abruzzo region believed the Pandafeche creature was to blame for their sleep paralysis. Italians, like Egyptians, were more likely to have sleep paralysis, which was characterized by protracted paralysis and an exaggerated terror of the experience. Beliefs about the disease exacerbated symptoms in both groups, resulting in a strange mind-body interaction with “nocebolike” effects. The potential of an engaged imagination to influence bodily events was astounding.
According to these studies, the more people fear sleep paralysis, the more they encounter it and the more severe its consequences are. What were once regarded to be benign, even imaginative, ideas have triggered conditioned anxiety and colored the content of hallucinations, transforming the disease. Anxiety and stress make people more vulnerable to attacks, so those who fear them are more likely to have one. In fact, compared to Denmark, sleep paralysis is nearly twice as common in Egypt. Those who believe their sleep paralysis is caused by a supernatural force are also more prone to hallucinate during the episode, including experiencing a ghostly “sensed presence,” as discovered in Italy. Sleep paralysis is then viewed via the lens of fear, resulting in increased anxiety and unwelcome awakeningsand, in effect, more sleep paralysis. This vicious loop, which I refer to as the “panic-hallucination model,” feeds on itself until sleep paralysis becomes chronic, long-lasting, and potentially psychopathological.
Our new findings suggest the intriguing notion that sleep paralysis, when accompanied by certain beliefs, can be both terrifying and distressing. Long after an episode has ended, the effects can persist. In one study in Egypt, we discovered that persons who have witnessed the event have higher levels of trauma and anxiety symptoms than those who have not. Those who have visual hallucinations, such as seeing “demonic entities,” are more more vulnerable. In a recent study in Abruzzo, my colleagues and I discovered that panic during sleep paralysis, as well as fear of dying as a result of the attack, were connected to trauma and depression symptoms. These findings suggest that the disease can create psychopathology when viewed via a specific cultural lens.
Sleep is not an escape from reality for those who suffer from sleep paralysis. Indeed, “sleeping” can contribute to mental illness in some people. The human mind is far more mysterious, and sometimes cruel, than one may think.
Are your eyes open during sleep paralysis?
The most common symptom of sleep paralysis is being fully aware of your surroundings yet unable to move or speak for a short period of time. This normally happens when you're waking up, but it can also happen while you're sleeping.
- Take deep breathes with difficulty, as if your chest is being squashed or limited
- be able to move your eyes – some people are able to open their eyes, while others are unable to do so.
- Have the impression that someone or something is in the room with you (hallucination) many people believe this presence is attempting to harm them.
An episode might last anything from a few seconds to many minutes. Sleep paralysis affects many people once or twice throughout their lives, while others get it many times a month or more frequently.
After that, you'll be able to move and speak normally, though you could feel unsettled and concerned about sleeping again.
Is sleep paralysis a dream or real?
Parasomnia is a term used to describe sleep paralysis. Parasomnias are sleep-related aberrant activities. Sleep paralysis is classified as a REM parasomnia since it occurs during the rapid eye movement (REM) portion of the sleep cycle.
A typical REM sleep cycle includes vivid dreaming as well as atonia, which prevents dream actors from carrying out their fantasies. Atonia, on the other hand, stops when a person wakes up, therefore a person is never aware of their incapacity to move.
Does anxiety cause sleep paralysis?
Many of these characteristics exhibited only a weak or unclear association, however poor sleep quality was undeniably linked to sleep paralysis events. The review discovered that the less peaceful a person's sleep was, the more likely they were to develop sleep paralysis.
“Overall, several elements linked to interrupted sleep appear to be linked to sleep paralysis,” Gregory added. “Those who use substances, are stressed, or have psychiatric problems, for example, are more likely to have disrupted sleep.”
Individuals who awoke frequently during the night were shown to be considerably more likely than sound sleepers to develop paralysis episodes in various studies. Individuals who slept for fewer than 6 hours or more than 9 hours at a time were more likely to develop sleep paralysis upon waking, according to various studies. Napping has also been linked to an increased risk of sleep paralysis.
“When we think about the likely mechanisms behind sleep paralysis,” Gregory said, “this makes sense.” Sleep paralysis happens when a person is trapped between REM sleep and alertness.
The review discovered that stress and worry are associated to a person's risk of experiencing sleep paralysis. Multiple studies found that people with post-traumatic stress disorder (PTSD) had much greater rates of sleep paralysis than patients without the disease. People with social anxiety and overall stress were more likely to have sleep paralysis episodes than those without these characteristics, although only to a smaller amount. In addition, some studies have discovered a link between sleep paralysis and nightmares.
“It's possible that stress causes sleep paralysis, but it's also possible that stress causes sleep paralysis,” Gregory added. “It was difficult to separate cause and effect.” She said that further long-term studies will help determine which emerges first: sleep issues or anxiety.
