What is sleep paralysis?

Sleep paralysis is a sleeping disorder that makes you feel paralyzed in your sleep. It must be pretty clear with the name itself. Sleep paralysis is a condition where you feel conscious in your sleep and are yet unable to move.

You might feel a temporary loss of muscle function during sleep paralysis. It usually occurs when you are in a transition state from wakefulness to sleep or vice versa. Sleep paralysis is generally accompanied by an inability to sleep or move for a few seconds or a few minutes, even if you are conscious.

Sleep paralysis might also occur shortly after you have fallen asleep. Hence, you might experience disturbed sleep patterns due to sleep paralysis. If you dig deeper into scary facts about sleep, you will realize sleep paralysis is a result of your mind and body getting out of sync. 

Why do we experience sleep paralysis?

Sleep paralysis is not one of the demon things about sleep. It has a well-established scientific reason behind it. If you come across scary sleep facts, you would notice what causes sleep paralysis is when your body wakes up in a state of sleep.

In simple words, our body has a mechanism of relaxing while asleep, and the voluntary muscles do not move. It is designed to keep people from hurting themselves while they act out in dreams.

However, when you wake up in that relaxed state of your body with your voluntary muscles still unable to move, you experience sleep paralysis. You might experience hypnopompic or hypnagogic hallucinations during sleep paralysis. Hence, this explains what causes sleep paralysis, as many scary sleep facts state.

What are the types of sleep paralysis?

Through the above discussion on scary sleep facts and what causes sleep paralysis, you must have noticed two terms, hypnogogic and hypnopompic hallucinations. These are nothing but the types of sleep paralysis you might experience. The two are differentiated based on what phase of your sleep you experience sleep paralysis.

When you experience sleep paralysis as you are just about to sleep, that is the transition from wakefulness to sleep; the condition is known as hypnagogic or predormital sleep paralysis. On the other hand, when you experience sleep paralysis while waking up from your sleep, that is, the transition from sleep to wakefulness, the condition is termed hypnopompic or postdormital sleep paralysis.

The two types of sleep paralysis have different symptoms and causes. Hence, if you need an answer to what causes sleep paralysis, you must know what kind of sleep paralysis you experience the most.

What causes sleep paralysis?

So now that you are deeper into scary sleep facts, it is time to know what causes sleep paralysis. However, you must first know how the body functions during sleep and the transitions that take place as you sleep and wake up.

There are phenomena called Rapid eye movement (REM) and Non-rapid eye movement (N-REM). The body undergoes a REM-NREM cycle for about 90 minutes, during which the time spent sleeping falls under the Non-rapid eye movement phase. 

Our body relaxes during the Non-rapid eye movement phase. On the other hand, the body is still relaxed during the Rapid eye movement phase, but the eyes move quickly. We experience dreams under the Rapid eye movement phase.

However, when the transition between REM and NREM is out of sync with the brain, it is what causes sleep paralysis. During sleep paralysis, you keep alternating between the Rapid eye movement and Non-rapid eye movement phase. Hence, you find yourself unable to speak or move even if you are in a conscious state. 

Hence, the brain becomes over-sensitive to threats and goes on to a heightened state. So now that you know what causes sleep paralysis, you know a lot of scary facts about sleep. However, hold on as there is more to cover on scary sleep facts that would tell you interesting things about sleep.
