Imagine this: You’re sleeping peacefully when suddenly you wake up, but not because of your alarm clock. Your eyes are open, and you feel like something heavy is sitting on your chest, holding you down. You try to scream, but no sound comes out. You want to get up and run, but you can’t move at all. It feels like you’re trapped in a nightmare, even though you’re awake.
This strange and scary experience is called sleep paralysis. It’s something that about half of all people will experience at least once in their lives. During these episodes, which can last from a few seconds to a few minutes, you might see or hear things that aren’t really there. Some people even think they’ve seen ghosts or been visited by aliens!
In 1867, a doctor named Silas Weir Mitchell was the first to study sleep paralysis. He described it as a state where you’re aware of your surroundings but can’t move. Even before Dr. Mitchell’s research, people all over the world had their own explanations for sleep paralysis.
Today, scientists think sleep paralysis happens because of an unusual overlap between REM (rapid eye movement) sleep and waking up. During REM sleep, you dream, and your brain is fully asleep. Your body releases chemicals that temporarily paralyze your muscles so you don’t act out your dreams.
When sleep paralysis occurs, you’re experiencing parts of REM sleep while you’re awake. You’re dreaming, and your muscles are paralyzed, but your mind is conscious. This is why it feels like there’s a scary presence in the room with you.
The feelings of panic, choking, or pressure on your chest are your body’s natural reaction to what it thinks is an attack. During REM sleep, you lose voluntary control of your breathing, which can make your breaths shallow and quick. This can create a sensation of pressure or suffocation.
Some people experience sleep paralysis regularly, and it might be linked to sleep disorders like narcolepsy. However, many people only experience it once in their lifetime. So, you can relax knowing that there’s no evil entity trying to haunt or suffocate you. Save those fears for horror movies!

Imagine this: You’re fast asleep when all of a sudden you’re awoken! And not by your alarm clock. Your eyes open, and there’s a presence sitting on your chest, pinning you down. You try to open your mouth and scream, but no sound comes out. You try to get up and run away, but you realize that you are completely immobilized. This presence seems to be trying to suffocate you, but you can’t fight back. You’ve awoken into your dream, and it’s a nightmare.
This experience is known as sleep paralysis, and about half of the population has encountered this phenomenon at least once in their life. This panic-inducing episode can last anywhere from seconds to minutes and may involve visual or auditory hallucinations. Some have even mistaken sleep paralysis for an encounter with a ghost or an alien abduction.
In 1867, Dr. Silas Weir Mitchell was the first medical professional to study sleep paralysis. He described it as a state where the subject is aware of their surroundings but is incapable of moving. Although Dr. Mitchell was the first to observe patients in this state, sleep paralysis is so common that nearly every culture throughout history has had some kind of explanation for it.
In medieval Europe, people believed that an incubus visited them at night. In Scandinavia, a figure known as the mare was thought to sit on sleepers’ rib cages. In Turkey, a jinn was believed to hold people down. In Thailand, Phi Am was said to bruise sleepers. In the southern United States, the hag was a common explanation. In Mexico, it was referred to as “subirse el muerto,” or “the dead person.” In Greece, Mora was thought to sit upon the chest and try to asphyxiate individuals. In Nepal, Khyaak the ghost was said to reside under the staircase.
Modern scientists believe that sleep paralysis is caused by an abnormal overlap of the REM (rapid eye movement) and waking stages of sleep. During a normal REM cycle, you experience sensory stimuli in the form of a dream, and your brain is unconscious and fully asleep. Special neurotransmitters are released during your dream, which paralyze almost all of your muscles, preventing you from acting out your dreams.
During an episode of sleep paralysis, you’re experiencing normal components of REM sleep. You’re dreaming, and your muscles are paralyzed, but your brain is conscious and awake. This is what causes you to imagine that you’re having an encounter with a menacing presence.
The feelings of panic, choking, or chest pressure that many people describe can be explained by the body’s fear response to a perceived attack. During REM sleep, the mechanism that prevents you from acting out your dreams also removes voluntary control of your breathing. This can lead to shallow and rapid breaths, causing a sensation of pressure on the chest or suffocation.
While some people experience sleep paralysis regularly, it may be linked to sleep disorders such as narcolepsy. Many who experience it do so infrequently, perhaps only once in a lifetime. So you can rest easy, knowing that an evil entity is not trying to haunt or suffocate you. Save that for the horror films!
Sleep – A natural state of rest for the body and mind, during which consciousness is suspended and the body undergoes various restorative processes. – During sleep, the brain processes information and consolidates memories from the day.
Paralysis – A condition where a person is unable to move certain parts of their body, often due to nerve or muscle issues. – Sleep paralysis can occur when a person is waking up or falling asleep, causing temporary inability to move.
Dreams – Sequences of images, thoughts, or emotions occurring involuntarily in the mind during certain stages of sleep. – Many people experience vivid dreams during the REM stage of sleep.
Brain – The organ in the head that controls thoughts, memory, emotions, touch, motor skills, vision, breathing, and every process that regulates our body. – The brain is highly active during sleep, especially when we dream.
Muscles – Tissues in the body that have the ability to contract, enabling movement of body parts. – During REM sleep, most of the body’s muscles are temporarily paralyzed to prevent acting out dreams.
Panic – A sudden, overwhelming feeling of fear or anxiety that can cause physical symptoms like increased heart rate and shortness of breath. – Some people wake up in a panic after experiencing a nightmare.
Pressure – The force exerted on an object or surface, often related to stress or tension in a psychological context. – High levels of stress and pressure can affect sleep quality and lead to insomnia.
Awareness – The state of being conscious of something, including thoughts, feelings, and surroundings. – Mindfulness practices can increase awareness and improve mental health.
REM – Rapid Eye Movement, a stage of sleep characterized by quick movements of the eyes, vivid dreams, and increased brain activity. – REM sleep is essential for cognitive functions like memory and learning.
Nightmares – Frightening or unpleasant dreams that can cause a person to wake up feeling scared or anxious. – Nightmares are more common in children and can be triggered by stress or trauma.
