  https://my.clevelandclinic.org/health/diseases/21974-sleep-paralysis

  Sleep paralysis is when you cant move any part of your body right before falling asleep or as you wake up. It happens when your body is in between stages of sleep and wakefulness. […] The exact cause of sleep paralysis is unknown. Healthcare providers notice they could happen with the following: Narcolepsy, Not sleeping enough (sleep deprivation), An irregular sleep schedule (shift work sleep disorder), Obstructive sleep apnea, Mental health conditions like anxiety, bipolar disorder, post-traumatic stress disorder (PTSD) or panic disorder, Certain medications (like ones that treat ADHD), Substance use disorder (SUD). […] Sleep paralysis happens when you regain awareness going into or coming out of rapid eye movement (REM) sleep. Your body hasnt fully switched sleep phases or woken up during sleep paralysis.

  Sleep paralysis (SP) is a phenomenon wherein individuals awaken from deep sleep but are unable to move or speak, often experiencing vivid hallucinations. This condition, attributed to the persistence of muscle atonia from rapid eye movement (REM) sleep into wakefulness, is associated with factors like sleep deprivation and irregular sleep patterns. […] The primary symptom is the inability to move or talk upon awakening. […] SP involves a temporary inability to move or speak upon awakening, often with vivid hallucinations. It occurs when the muscle paralysis typical of REM sleep persists briefly into wakefulness. Factors like sleep deprivation and irregular sleep patterns influence this condition. Recent studies also highlight risk factors such as stress, psychiatric disorders, genetic predispositions, and, notably, hypertension.

• #3 Sleep paralysis: Causes, symptoms, and tips

  https://www.medicalnewstoday.com/articles/295039

  Sleep paralysis occurs when a persons consciousness is awake, but their body is still in a paralyzed sleep state. […] In sleep paralysis, the bodys transition to or from rapid eye movement (REM) sleep is out of sync with the brain. The persons consciousness is awake, but their body remains in the paralyzed sleep state. […] Factors that may increase the risk of sleep paralysis include: narcolepsy, irregular sleeping patterns, due to things like jet lag or shift work, a family history of sleep paralysis. […] Sleep paralysis can be a symptom of medical problems, including: depression, migraine, obstructive sleep apnea, hypertension, anxiety disorders. […] Many people will experience sleep paralysis only once or twice in their life. However, people with narcolepsy and other sleep disorders have a higher risk of experiencing sleep paralysis.

  SP happens when atonia is based on REM and persists into awakening. […] More than 75% of SP episodes also include numerous bizarre and often terrifying hallucinations in addition to ongoing muscle atrophy. […] SP is when voluntary muscular movements are stopped at the start of sleep or upon waking up. […] SP occurs frequently in the general population and has a unique and dramatic clinical appearance. […] During sleep, the body cycles through REM and non-rapid eye movement (NREM) stages. REM sleep involves heightened brain activity, increased heart rate and blood pressure, and faster breathing. […] SP blurs the line between sleeping and waking states. It involves temporary muscle paralysis lasting seconds to minutes, during which individuals are conscious but unable to move. […] The study’s findings indicate that SP occurs when an individual wakes from deep sleep but is temporarily unable to move or speak. This phenomenon is largely attributed to continuous muscle paralysis associated with REM sleep, a phase characterized by vivid dreaming and complete muscle immobilization.

  https://www.webmd.com/sleep-disorders/sleep-paralysis%231

  Sleep paralysis is not usually something to worry about. But about 10% of people have recurrent sleep paralysis, which can be a symptom of a more serious problem. If you have frequent episodes of sleep paralysis, then you may have a sleep disorder called narcolepsy. There are also serious mental illnesses that can involve sleep paralysis, including posttraumatic stress disorder (PTSD), bipolar disorder, and anxiety or panic disorders. These conditions can disrupt sleep patterns, making sleep paralysis more likely to happen. […] Just why or how it happens isn’t clear. Researchers believe sleep paralysis is caused by a disturbed rapid eye movement (REM) cycle because it mostly happens as people are falling into or coming out of REM sleep. During that stage, your brain normally paralyzes your muscles anyway so they don’t act out your dreams. But during sleep paralysis, your mind is awake, or half awake, and so you are aware you can’t move.

• #7 How sleep paralysis works | University of Toronto

  https://www.utoronto.ca/news/how-sleep-paralysis-works

  New University of Toronto research shows that two powerful brain chemical systems work together to paralyze skeletal muscles during rapid eye movement (REM) sleep. […] The findings may help scientists better understand the causes of sleep disorders such as narcolepsy, tooth grinding, and REM sleep behaviour disorder. […] Understanding the precise mechanism behind these chemicals role in REM sleep disorder is particularly important because about 80 percent of people who have it eventually develop a neurodegenerative disease, such as Parkinsons disease. […] Previous research had suggested that only the neurotransmitter receptors for glycine caused sleep paralysis. However, when the researchers blocked these receptors, sleep paralysis still occurred. […] The data suggest the two neurotransmitters must both be present together to maintain motor control during sleep, rather than working separately. […] By identifying the neurotransmitters and receptors involved in sleep-related paralysis, this study points us to possible molecular targets for developing treatments for sleep-related motor disorders, which can often be debilitating.

  https://en.wikipedia.org/wiki/Sleep_paralysis

  Sleep paralysis is a state, during waking up or falling asleep, in which a person is conscious but in a complete state of full-body paralysis. […] The condition may occur in those who are otherwise healthy or those with narcolepsy, or it may run in families as a result of specific genetic changes. The condition can be triggered by sleep deprivation, psychological stress, or abnormal sleep cycles. The underlying mechanism is believed to involve a dysfunction in REM sleep. […] Research has found a genetic component in sleep paralysis. […] The characteristic fragmentation of REM sleep, hypnopompic, and hypnagogic hallucinations have a heritable component in other parasomnias, which lends credence to the idea that sleep paralysis is also genetic.

  Sleep paralysis is a relatively common sleep condition that is characterized by a temporary and usually brief loss of muscle control – known as muscle atonia – immediately after waking or falling asleep. […] Although the exact mechanisms driving sleep paralysis are still not entirely known, sleep scientists believe it is caused by an abnormal mixed state of wake and rapid eye movement (REM) sleep. REM sleep stage is where you spend most of your sleep time vividly dreaming. […] Sleep paralysis is therefore believed to be caused by a continuation of REM-induced muscle atonia into our waking state. It is for these reasons that sleep paralysis is often accompanied by dream-like hallucinations. During sleep paralysis, we are both consciously awake yet still locked in dream sleep.
