Sleep paralysis can feel like choking because you wake while your body is still in REM atonia, making chest muscles relaxed and breathing feel restricted even though the diaphragm keeps you getting air, and dream-like hallucinations plus a fear surge amplify the sensation; episodes are brief and typically not dangerous. There are several factors to consider for your next steps, including ruling out sleep apnea, REM sleep behavior disorder, or narcolepsy and seeking care if episodes are frequent, you act out dreams, or have daytime sleepiness; see below for red flags, prevention tips, and what to do during an episode.
If you've ever woken up unable to move, feeling pressure on your chest or like someone is choking you, you're not alone. Many people describe sleep paralysis feeling like I'm being choked in my sleep. The experience can be intense, vivid, and frightening.
But here's the important truth: in most cases, sleep paralysis is not life-threatening. It's a temporary state where your brain and body are out of sync during sleep.
Let's break down what's really happening, why it can feel like a struggle or choking, and when you should seek medical advice.
Sleep paralysis happens when you wake up (or fall asleep) and temporarily cannot move or speak. It typically lasts a few seconds to a couple of minutes.
During normal sleep—especially during Rapid Eye Movement (REM) sleep—your brain turns off most muscle activity. This is called REM atonia. It prevents you from physically acting out your dreams.
In sleep paralysis:
That overlap between dreaming and wakefulness is what creates the powerful sensations.
Many people specifically report:
Here's why that happens.
During REM sleep:
When you wake up during this state, your breathing may feel restricted. Even though you are getting enough air, it can feel like you are suffocating.
That sensation can easily translate into:
The feeling is real — but the cause is neurological, not someone physically choking you.
During sleep paralysis, parts of your brain that create dreams are still active. That means:
The brain is very good at building a story to explain unusual body sensations. If your chest feels tight, your brain may create the idea of someone choking you.
This is called a hypnopompic or hypnagogic hallucination, depending on when it happens.
When you wake up and cannot move:
That surge of stress can amplify the choking sensation. It becomes a feedback loop:
Sleep paralysis is more common than most people think.
Research suggests:
The "choking" version of sleep paralysis is one of the most commonly reported forms.
Across cultures, people have described nearly identical experiences for centuries — often explained in spiritual or supernatural terms before science understood REM sleep.
In most cases, sleep paralysis is not physically dangerous.
However, it can:
The key is distinguishing between sleep paralysis and other potentially serious conditions.
Sometimes, a choking sensation at night may not be sleep paralysis.
Speak to a doctor if you experience:
In particular, if you physically move, kick, shout, or act out dreams, that could suggest something different. If you're experiencing these symptoms, you can use Ubie's free AI-powered Rapid Eye Movement (REM) Sleep Behavior Disorder symptom checker to help identify whether your nighttime experiences align with this specific sleep disorder before speaking to a healthcare professional.
Remember: online tools are not a diagnosis. If something feels serious or life-threatening, seek medical care immediately.
Sleep paralysis is powerful because:
That combination convinces your brain that the threat is real.
Brain imaging studies show that during these episodes:
In other words, your brain is in a mixed state between dreaming and being awake.
Most episodes:
Even though it feels much longer, the actual duration is usually brief.
If you frequently experience sleep paralysis feeling like I'm being choked in my sleep, improving sleep habits can significantly reduce episodes.
Sleep paralysis is more common when lying on your back. You might try:
If it happens again:
Knowing what's happening often reduces the fear dramatically.
You should speak to a doctor if:
If you ever experience real breathing difficulty, chest pain, or prolonged choking while awake, seek urgent medical attention.
If you experience sleep paralysis feeling like I'm being choked in my sleep, you are likely experiencing a well-documented REM-related phenomenon where:
It feels real because your brain makes it real. But in most cases, it is not dangerous.
Still, don't ignore persistent or severe symptoms. Speak to a doctor about anything that feels serious, life-threatening, or unusual. Sleep disorders are treatable, and getting clarity can bring real peace of mind.
Understanding what's happening is often the first and most powerful step toward reducing fear — and reclaiming restful sleep.
