Hypnagogic Sensations: Definition, and 4 Causes

Hypnagogic Sensations: Definition, and Causes – Sleep is one way for our body to rest and recharge to be comfortable. That’s why when we get enough sleep, we’ll wake up with a fresh, vibrant body. Conversely, sleep deprivation can cause us to be sleepy, limp, or even dizzy while on the move.

There are various sleep disturbances that can keep us from getting enough sleep.

One of the most frequent is a falling dream that makes us jerk and wake up. Who’s going through it a lot?

Some of you must have experienced the sensation of falling into a ravine,

We must have at least once felt a very real fall dream, which made us finally wake up shocked with a beating heart.

There are some people who can go straight back to sleep again, but some people even think of the dream over and over again, terrified.

But actually, dreams fall while sleeping, then waking up is very common experienced by many people.

This sensation is known as a hypnagogic jerk, which is a subconscious muscle spasm that occurs when a person falls asleep. This explains, according to Tom Stafforda in Bustle, usually, dreams occur when it is in the REM phase where the muscles are being paralyzed.

This fall sensation occurs if you start dreaming before the body is completely deactivated. As a result, the body is confused because it is still in a transition period between waking up and sleeping well.

What are hypnagogic hallucinations?

Hypnagogic hallucinations are when our body muscles twitch unconsciously and unwantedly.

It usually happens when our muscles are relaxed to fall asleep, but our brains are still active and can’t keep up with our muscles to fall asleep and relax.

As a result, the brain instead sends distress signals throughout the body, so we can’t fall asleep and be alert.

Hypnagogic Sensations Causes

Although the researchers aren’t sure what the cause is, this hypnagogic jerk is more likely to occur when you’re sleeping very tired, sleep-poor or stressed. This condition makes the brain wants to get to sleep quickly, but the body misses far to match the speed of the brain.

Too tired

When too tired, whether mind or body, usually the brain will still run as an effect because it has not been able to quit the work we just did.

As a result, the brain will ‘wake up’ us in a hypnagogic sensations.

It can also mean that the fatigue you feel is out of bounds and can cause you to fall ill.

So wherever possible, we should relax and take enough time to rest.


When we are stressed or worried about something, our brain will continue to be active and alert so that it can quickly solve the problem.

The thing is, our brain will continue to be active even if our body is relaxed and wants to fall asleep.

When we’re about to go to sleep, the brain will send a signal to wake up, so we can stay alert and just in case, because we’re still stressed.


There’s a reason why we can’t exercise too long and get too close to our bedtime.

This is because our brains and muscles have not been able to stop “moving” from the exercises we do, so the brain and muscles will continue to be active, even though we should have slept.

Examples of exercise that would create hypnagogic hallucinations are long swims or heavy cardio and long before bedtime.

Chemical material

The chemicals in question are caffeine or nicotine.

If one of these two ingredients gets into our body before bed, usually the chemical can interfere with our ability to fall asleep anyway.

This is because both caffeine and nicotine will produce something that disrupts our sleep and wakes up immediately.
