What Is Sleep Paralysis?
Have you ever woken up and felt unable to move your body? Maybe you tried to speak, but no sound came out. Some people also feel pressure on their chest or think they see a strange shadow in the room.
This experience is called sleep paralysis.
Sleep paralysis happens when your brain wakes up before your body fully wakes up. During deep sleep, the body naturally relaxes and temporarily stops most movement. Sometimes the mind becomes awake too early, while the body is still in “sleep mode.”
Although sleep paralysis can feel frightening, it is usually not dangerous.
Common Symptoms of Sleep Paralysis
People who experience sleep paralysis may:
Be unable to move their arms or legs
Feel pressure on the chest
Have difficulty speaking
Feel fear or panic
See shadows or figures
Hear strange sounds or whispers
Feel like someone is in the room
Episodes usually last from a few seconds to a few minutes.
Why Does Sleep Paralysis Happen?
Experts believe sleep paralysis is connected to poor sleep habits and stress.
Some common causes include:
Lack of sleep
Stress and anxiety
Sleeping at irregular times
Jet lag
Sleeping on the back
Exhaustion
Students, office workers, and people with busy schedules may experience it more often.
Sleep Paralysis Around the World
Many cultures have traditional stories about sleep paralysis. Before modern science, people often believed supernatural beings caused the experience.
Different countries have their own explanations and legends.
Sleep Paralysis in the Philippines
In the Philippines, many people call sleep paralysis “bangungot.”
Some Filipinos believe a spirit or creature sits on a sleeping person’s chest during the night. Older generations sometimes connect it to ghosts or supernatural beings.
However, doctors explain that bangungot is related to sleep disorders and stress.
Even today, many Filipinos still share scary stories about waking up unable to move.
Japan’s Counterpart: Kanashibari
In Japan, sleep paralysis is called kanashibari (金縛り).
The word literally means “bound by metal” or “fastened in metal.” It describes the feeling of being completely unable to move.
Long ago, some Japanese people believed kanashibari was caused by spirits, curses, or supernatural forces. Japanese ghost stories, horror movies, and anime sometimes include scenes of kanashibari.
Today, scientists in Japan explain kanashibari as a natural sleep phenomenon, just like sleep paralysis in other countries.
Still, many Japanese people describe it as a very frightening experience because it can feel extremely real.
Similar Beliefs in Other Countries

United States

Is Sleep Paralysis Dangerous?
Sleep paralysis is usually not dangerous.
However, frequent episodes may affect sleep quality and mental health. If it happens often, doctors recommend improving sleep habits and reducing stress.
People should talk to a doctor if:
Sleep paralysis happens frequently
They feel very anxious about sleeping
They often feel tired during the day
They experience other sleep problems
How to Reduce Sleep Paralysis
Here are some helpful tips:
1. Get Enough Sleep
Try to sleep 7–9 hours every night.
2. Keep a Regular Sleep Schedule
Go to bed and wake up at the same time every day.
3. Reduce Stress
Relax before sleeping. Reading, stretching, or listening to calm music may help.
4. Avoid Sleeping on Your Back
Some people experience sleep paralysis more often in this position.
5. Limit Screen Time Before Bed
Phones and computers can make it harder to sleep deeply.
Interesting Fact
Scientists believe many “ghost sightings” throughout history may actually have been sleep paralysis experiences.
Because people cannot move and may see hallucinations, the experience can feel very real.
