Sleep paralysis, also known as ReM atony, is a temporary disability to move or speak during the transition between sleep and vigil. It is a phenomenon that occurs during the fast ocular movements phase (mor), which is characterized by vivid dreams. During this phase, the brain sends signals to the muscles to prevent dreams from representing, which causes temporary muscle paralysis that protects us from physically representing our dreams. However, in cases of sleep paralysis, this paralysis persists for a few seconds a few minutes after waking up or just before falling asleep.
- Sleep paralysis symptoms may include
- Chest pressure sensation
- Difficulty breathing or drowning sensation
- Hallucinations, often accompanied by a feeling of fear or imminent fatality.
- Feeling of being caught or not being able to move
- An overwhelming feeling of fear
Sleep paralysis can be an distressing experience that leaves defenseless and scared people. It is important to note that, although sleep paralysis can be a symptom of underlying sleep disorder, such as narcolepsy or sleep apnea, it can also occur in healthy people. The exact cause of sleep paralysis is not fully known, but certain risk factors, such as irregular sleep schedules and high levels of stress have been identified. It is recommended to go to the doctor if sleep paralysis episodes are frequent, significantly alter sleep quality or are accompanied by other worrying symptoms.
Understanding the definition and symptoms of sleep paralysis is crucial for people who experience this phenomenon. By recognizing and controlling possible trigger factors, people can take measures to mitigate the frequency and impact of sleep paralysis episodes, improving the general quality of sleep and wel l-being.

Sleep Paralysis: Understanding the Phenomenon
The phases of sleep:
- Vigil: It is the state of full consciousness in which the brain is active and the body can move freely.
- Phase 1 of the sleep: During this phase, which usually lasts for a few minutes, the brain produces alpha and theta waves. It is a transition phase between vigil and sleep.
- Stage 2 sleep: In this stage, the brain produces specific patterns of brain waves known as sleep spindles and K complexes. It is a deeper sleep state than Stage 1. It is a deeper sleep state than stage 1.
- Rapid eye movement (REM) sleep: REM sleep is characterized by rapid eye movements, vivid dreams, and temporary paralysis of skeletal muscles. This phase is considered the deepest of sleep.
“Sleep paralysis usually occurs during the transition from REM sleep to wakefulness, when the brain is active but the body remains temporarily paralyzed. This phenomenon is the result of the dissociation between the brain’s sleep and wake systems.”
Understanding sleep paralysis:
Sleep paralysis can be an incredibly distressing experience, often accompanied by vivid hallucinations and a sense of impending doom. Although the exact causes are not completely known, they are believed to be related to disturbances in the REM sleep cycle and associated muscle atonia. Factors such as sleep deprivation, irregular sleep schedules, and certain sleep disorders can increase the likelihood of experiencing sleep paralysis.

What is Sleep Paralysis?
During an episode of sleep paralysis, the brain is awake while the body remains in a state of muscle atonia, a natural paralysis that occurs during REM (rapid eye movement) sleep to prevent us from acting out our dreams. However, in sleep paralysis, the mind wakes up before the paralysis wears off, causing a temporary state of immobility. This state can last from a few seconds to a couple of minutes, making the person feel trapped and unable to move. The experience can be frightening, as people may also perceive the presence of threatening figures or auditory hallucinations.
It is important to note that sleep paralysis is relatively common, with around 8% of the general population experiencing it at least once in their life. It can occur in people of all ages, but is most common in adolescents and young adults. Sleep deprivation, irregular sleep patterns, stress, certain medications, and sleep disorders such as narcolepsy have been associated with a higher likelihood of experiencing sleep paralysis.
It is estimated that about 40% of people with narcolepsy, a neurological disorder characterized by excessive daytime sleepiness, also suffer from sleep paralysis.
- Sleep paralysis can be classified into two main types: isolated sleep paralysis and recurring isolated sleep paralysis.
- In the paralysis of the isolated sleep, episodes occur low and are not associated with any underlying disease.
- Recurrent isolated sleep paralysis, on the other hand, refers to the presence of repeated episodes over time, often accompanied by other slee p-related disorders.
- Although the cause of sleep paralysis is still not known exactly, several factors that can contribute to it have been identified:
- Dream-Vigilia cycle alterations
- Genetic predisposition
- Stress and anxiety
- Sleep disorders
| Sleep paralysis symptoms: | Possible explanations: |
|---|---|
| Immobility | Atony rem still |
| Visual and auditory hallucinations | Brain hyperactivation, dreamlike state |
| Feeling of imminent danger or presence of threatening figures | Activation of the amygdala, brain region involved in the response to fear |
The Science behind Sleep Paralysis
Stages of sleep and paralysis: During a typical sleep night, our brain goes through multiple stages, including sleep without rapid ocular movements (NREM) and sleep with rapid ocular movements (REM). The Nrem dream consists of several stages, which begin somnolence and progress to deep sleep. It is during the ReM sleep when most dreams occur and, curiously, it is also when sleep paralysis is more likely. During the REM dream, the brain becomes very active, similar to when we are awake, while the body is paralyzed to prevent us from carrying out our dreams.
ATIA REM: REM atony, also known as muscle atony related to REM, is the temporary paralysis state that occurs during REM sleep. This paralysis is triggered by the release of inhibitory signs of the brain trunk to motor neurons, effectively preventing voluntary muscle movements. However, in some cases, this paralysis continues to pass from sleep to the vigil, which gives rise to sleep paralysis.
- Hallucinations and fear: One of the most striking characteristics of sleep paralysis is the presence of vivid hallucinations. These hallucinations can vary in content, from benign experiences to elaborate and terrifying scenarios. They are believed to be the result of the brain’s attempt to make sense of the disconnection between the dream and waking worlds. The fear and anxiety often experienced during sleep paralysis can be attributed to the combination of hallucinations and the individual’s awareness of their inability to move or escape.
Understanding the science behind sleep paralysis provides valuable information about the intricate workings of our sleep-wake cycle and the mechanisms that regulate our movements during sleep. Further research into this phenomenon is essential to unravel the underlying causes and develop effective treatments for people who suffer from sleep paralysis regularly.
Symptoms of Sleep Paralysis
Hallucinations: One of the most common symptoms of sleep paralysis is hallucinations. These hallucinations can be visual, auditory or tactile. Visual hallucinations can range from seeing shadowy figures or shapes in the room to vivid, real images. Auditory hallucinations, on the other hand, consist of hearing sounds, voices or music that are not present in reality. Tactile hallucinations can include the sensation of being touched, grabbed, or pressed on various parts of the body.
- visual hallucinations
- auditory hallucinations
- Tactile hallucinations
Feeling of pressure in the chest: Another common symptom of sleep paralysis is a feeling of pressure in the chest. Many people describe this feeling as if they had someone sitting on their chest or a heavy weight pressing down on them. This can cause discomfort, difficulty breathing, and a feeling of fear or panic. It is important to note that this feeling of pressure is not the result of any external physical force, but rather a manifestation of the sleep paralysis episode.
Inability to move or speak: The characteristic symptom of sleep paralysis is the temporary inability to move or speak. It is usually accompanied by the feeling of being paralyzed or trapped in one’s own body. Despite the intense desire to move or ask for help, the individual is unable to do so. This feeling of paralysis can be incredibly distressing and lead to feelings of helplessness or even panic.
- Feeling of pressure in the chest
- Inability to move or speak
Types of Sleep Paralysis
1. Isolated sleep paralysis:
Isolated sleep paralysis, also known as episodic sleep paralysis, refers to the appearance of sleep paralysis episodes infrequently and randomly. People with isolated sleep paralysis may experience it once or have isolated episodes throughout their lives. It is usually related to sleep deprivation, irregular sleep schedules or alterations of the sleep-vigilia cycle.
- Occurs randomly and randomly
- It can happen one or several times throughout life
- Is related to sleep deprivation or irregular sleep patterns
Isolated sleep paralysis is usually not associated with any underlying disease or sleep disorders. It is considered a normal phenomenon that can be triggered by various factors, such as stress increase, insomnia, time lag or sleeping hours.
2. Recurrent sleep paralysis:
Recurrent sleep paralysis, as the name implies, consists in experiencing sleep paralysis episodes regularly and recurring. Individuals with this type of sleep paralysis usually have frequent episodes, sometimes even several times a week. Recurrent sleep paralysis is usually associated with underlying sleep disorders, such as narcolepsy or sleep apnea, and it is believed that it is caused by interruptions in the REM phase (rapid ocular movements) of sleep.
- Occurs regularly and frequency
- It can happen several times a week
- It is usually associated with sleep disorders, such as narcolepsy or sleep apnea.
In cases of recurring sleep paralysis, it is essential to consult a healthcare professional to perform an exhaustive evaluation and diagnosis. The treatment of the underlying sleep disorder can often help relieve the frequency and severity of sleep paralysis episodes.
| Guy | Frequency | Associated factors |
|---|---|---|
| Isolated sleep paralysis | Uncommon and random | Irregular sleep patterns, irregular sleep patterns |
| Recurrent sleep paralysis | Regular and frequent | Sleep disorders (narcolepsy, sleep apnea) |
Causes and Triggers of Sleep Paralysis
1. Sleep deprivation: One of the main causes of sleep paralysis is sleep deprivation. When people do not sleep enough, their sleep cycles are altered, which increases the probability of experiencing sleep paralysis. Lack of sleep can alter the natural balance of sleep phases, especially the REM phase (rapid eye movements), in which sleep paralysis usually occurs. To reduce the risk of sleep paralysis, it is important to maintain a regular sleep schedule and sleep enough every night.
- Irregular sleep patterns: in addition to sleep deprivation, irregular sleep patterns can also trigger sleep paralysis episodes. Incoherent sleep habits, such as frequent changes in sleep or irregular alternation between day and night shifts, can alter the internal body of the body and increase the probability of sleep paralysis.
- Stress and anxiety: emotional and psychological factors such as stress and anxiety have been related to sleep paralysis. High levels of stress and anxiety can alter sleep quality and increase the chances of experiencing sleep paralysis episodes. Finding effective techniques to control stress and going to therapy or advice can help relieve these triggers.
It is essential to go to the doctor if sleep paralysis episodes become frequent, significantly affect daily functioning or are accompanied by other worrying symptoms. Only a medical professional can properly diagnose and treat sleep disorders.
In addition, some factors related to lifestyle and sleep disorders are also associated with sleep paralysis. Substance abuse, sleep apnea, narcolepsy and nightclubs in the legs have been identified as factors that can contribute to sleep paralysis. Identifying these triggers and addressing them through changes in lifestyle, therapy or medication can help control and prevent sleep paralysis episodes.
| Possible triggering factors of sleep paralysis: | Associated factors: |
|---|---|
| sleep deprivation | Interrupted sleep cycles |
| Irregular sleep patterns | Inconsistent sleep schedules |
| Stress and anxiety | Poor sleep quality |
| Substance abuse | Alteration of the balance of neurotransmitters |
How to Manage and Prevent Sleep Paralysis
Creating a coherent sleep schedule: Establishing a regular sleep routine can be beneficial to control sleep paralysis. Go to bed and get up at the same time every day helps regulate the internal body of the body, promoting a more repairing dream. In addition, avoiding caffeine, nicotine and alcohol near bedtime can improve sleep quality and reduce the probability of sleep paralysis.
Important: Maintaining a constant sleep schedule is crucial to control and prevent sleep paralysis. It helps to regulate the internal body of the body and favors a more repairing dream.
Practice good sleep hygiene: adopting healthy sleep habits can also help control sleep paralysis. Creating a relaxing sleeping environment keeping the cool, dark and quiet bedroom favors a quality dream. It is also recommended to practice relaxation techniques such as deep breathing exercises or meditation before bedtime. These practices can reduce stress and anxiety, which are usually associated with sleep paralysis episodes.
- Avoid using electronic devices, such as smartphones or tablets, in bed, since the blue light emitted can alter the sleep-vigilia cycle.
- Incorporate regular exercise to your daily routine, but avoid intense training near bedtime.
- Consider using white noise machines or ear plugs to create a quieter sleep environment.
Improve sleep quality: sleep quality plays a crucial role in prevention of sleep paralysis. It is important to create an environment conducive to sleep and give priority to sleep hygiene. In addition, people suffering from recurring episodes of sleep paralysis can benefit from consulting a healthcare professional, as a sleep specialist. This can provide more guidance and explore the possible underlying causes or contributing factors.
| Control and prevent sleep paralysis | Key strategies |
|---|---|
| Create a coherent sleep schedule | Regulate the internal body clock |
| Practice good sleep hygiene | Create a relaxing sleep environment and reduce stress |
| Improve sleep quality | Consult a health professional |
Sleep Paralysis and its Connection to Lucid Dreaming
In sleep paralysis, the brain passes from a state of consciousness to another, which causes a temporary disconnection between the mind and the body. When a person enters the sleeping phase of rapid ocular movements (MOR), which is usually associated with dreams, the brain releases chemical substances that inhibit movement. This mechanism, known as ATIA REM, prevents people from physically representing their dreams. However, in sleep paralysis, this inhibition continues even after the person has woken up, which causes the inability to move the body.
Sleep paralysis usually occurs during the transition between sleep and vigil, known as hypnagogical or hypnopompic state. It is a crucial phase in which the brain simultaneously maintains sleep and vigil elements. During this state, individuals may experience vivid hallucinations, such as seeing shady figures or listening to strange sounds, along with paralysis. It is important to note that these hallucinations are purely subjective and do not indicate any external reality.
- The lucid dream is a state of consciousness in which a person realizes that he is dreaming while the dream continues his course. This phenomenon allows individuals to have a certain degree of control over sleep content and their actions within it.
- Recent studies suggest that there is a close relationship between sleep paralysis and lucid dreams. It is believed that people who experience regular episodes of sleep paralysis are more likely to develop the ability to induce intentionally lucid dreams. This is because sleep paralysis creates a greater state of sel f-awareness and allows individuals to recognize that they are in a state of sleep.
Understanding the connection between sleep paralysis and lucid dreams can provide valuable knowledge about human brain mechanisms during different states of consciousness. A greater research in this field not only has the potential to reveal the mysteries that surround sleep disorders, but also offer opportunities for people to explore and take advantage of the unique experiences that occur during sleep paralysis and lucid dreams.
Debunking Myths about Sleep Paralysis
Myth #1: Sleep paralysis is a supernatural occurrence
One of the greatest false ideas about sleep paralysis is that it is caused by supernatural forces or demonic entities. This belief has its origin in the terrifying hallucinations that usually accompany the episodes of sleep paralysis. However, it is important to note that sleep paralysis has a scientific explanation based on sleep biology.
Sleep paralysis is a natural phenomenon that occurs when the brain and body are not synchronized during the sleep-vigilia transition. During the REM dream, the brain becomes very active, while the body is basically paralyzed to prevent dreams from producing. In sleep paralysis, this muscle paralysis persists for a brief period, even when the person enters vigil. The hallucinations that are experienced during sleep paralysis are the result that the brain tries to make sense of this state of confusion.
Myth #2: Sleep paralysis is a sign of a mental disorder
Another common myth about sleep paralysis is that it is a symptom of a mental disorder, such as psychosis or schizophrenia. While it is true that sleep paralysis may be more common in individuals with certain psychiatric conditions, it does not directly cause or indicate the presence of a mental disorder.
- Sleep paralysis is a neurological phenomenon that can affect people without any underlying psychiatric disorder. It is associated with altered sleep patterns, stress, sleep deprivation and certain sleep disorders.
- People with mental disorders may experience sleep paralysis more frequently due to their altered sleep patterns and general sleep disturbances. However, it is crucial to recognize that sleep paralysis itself is not a mental disorder, but rather a sleep-related condition.
