What is sleep paralysis? How is the experience interpreted in yoga tradition?

Every night we suffer from sleep paralysis. But we are not always aware of it. Sleep paralysis occurs while we are half awake and half asleep and we can’t move.

“Always when I’m going off to sleep. It’s pretty much the same”, Ted, a 35 year old British psychologist described his experiences of sleep paralysis. “My eyes are open and I get the sense something in the room is happening. Then a shape gathers. A presence. I can feel its weight. I have multisensory sensations. I feel like my body is floating. I can’t move it. I try to make a sound in my throat. I can’t. As I keep struggling to cry out, eventually scream out and that wakes me up and then I can move my body.”[1]

As I was thinking about writing this post, I kept hearing readers tell me, “You don’t know that sleep paralysis is similar to yoga meditation experiences. Who are you to speculate on the traditions and experiences of yogis, saints, and mystics?” I had my doubts about writing this post. While what I write may not adequately address all aspects of sleep paralysis and interpretations, I feel it is important anyway to write this article.

In between sleeping and waking, in this “threshold consciousness”, are a variety of mental phenomena that includes lucid dreaming, hallucinations, and sleep paralysis. I assert the sleep paralysis may be, in yoga tradition, what is interpreted as union with god, soul, or spirit. But more on that later. First, let’s return to what happens in our body during sleep paralysis.

What Happens During Sleep Paralysis?

While sleeping, your body alternates between REM (rapid eye movement) and NREM (non-rapid eye movement) sleep. One REM and one NREM sleep cycle lasts about 90 minutes. First is the NREM sleep cycle which takes as much as 75% of your overall sleep time. During NREM sleep, your body relaxes and rejuvenates itself. At the end of NREM, your sleep shifts to REM. Your eyes move rapidly, dreams occur while the rest of your body remains very relaxed. During REM your muscles are “switched off”. If you become aware and interrupt before the REM cycle is finished, you may notice you cannot move or speak. This is sleep paralysis.[2]

In Something Wicked This Way Comes: Causes and Interpretations of Sleep Paralysis Chris French, Professor and Psychologist at University of London, identified three psychological factors in the experience of sleep paralysis:

  1. Intruder — The person may sense a presence, hear voices or strange sounds, and see lights or visions. In a word–hallucinate.
  2. Incubus[3] — The experiencer may feel pressure, be unable to voluntarily control breathing, may panic creating a feeling of suffocation or difficulty breathing.
  3. Unusual body experiences — Sensations of floating, flying, or hovering, and out of body experiences. Proprioception, self-orientation within the body, is missing or out of order.

Sleep paralysis may evoke feelings of bliss or terror. The experience may be interpreted differently by different cultures or traditions. In Hinduism, Viśvarūpa is Sanskrit for “sacred terror”. Whether the experience is terrible or joyful is irrelevant. It’s the tradition and the interpretation that frames it as either sleep paralysis or sacred yoga.

How is sleep paralysis experience interpreted by yoga meditation tradition?

Yoga Tradition and Sleep Paralysis Experience

Famed yogi-guru, Paramahansa Yogananda, taught his students a “Definite Technique of Attaining Ecstasy:

“As you are falling asleep each night, keep your eyes half-open and focused at the point between the eyebrows; consciously enjoy in a relaxed nonchalant way the state at the border of joyous sleep as long as you can hold it without falling asleep, and you will learn to go into ecstasy at will. . . Try to remain in this state from five minutes to one hour, then you will know about yoga: conscious communion of your soul with God.”[4]

The practice of the yogi-guru’s technique (above) could result in what Western medicine and psychology says is sleep paralysis. Yogananda interprets sleep paralysis experience as “yoga: conscious communion of your soul with God”.

Another aspect of sleep paralysis which overlaps with yoga tradition is samadhi. Samadhi is by tradition the supreme goal of yoga (union or communion with God).

Let’s examine some similarities between so-called yoga samadhi and sleep paralysis.

Similarities Between Yoga Samadhi and Sleep Paralysis

When compared with sleep paralysis we find many similarities between yoga samadhi experiences, which include:

  • Immobilized body, unable to move
  • Altered or heightened awareness
  • Heard voices, sounds
  • Saw shapes, visions
  • Sensed presence
  • Disabled physical senses
  • Labored breathing
  • Panicked to breathe, speak, or move
  • Felt terror[5] or bliss (depending on experiencer interpretation)
  • Sensed floating, levitating
  • Hovered, outside, or “above” the physical body

To be aware is to experience. No awareness, no experience. After awareness of experience comes interpretation.

For instance, you become aware you can feel or control your “breathing”. Terror sets in. You panic. You gasp for breath. Or, you feel detached from your physical body. You feel bliss or terror.

I had panicked during yoga meditation. My awareness just landed on “not breathing” after feeling “outside” my body. I panicked and gasped for air. Coming back to voluntary control of my body.

An American-born swami-monk lectured around the world about the blessings of yoga meditation. The first time he practiced his guru’s yoga meditation technique, he told audiences he panicked when he became aware he was “not breathing”. Gasping finally resulted in sucking air into his lungs. Immediately the swami said he was brought back into his body consciousness.

Personal experiences like these are anecdotes, not proof the phenomena are objectively real. Returning now to the anecdotes reported by yogis and experiences of sleep paralysis patients, let’s examine the differences.

Differences Between Yoga Samadhi and Sleep Paralysis

Differences between sleep paralysis and yoga samadhi, includes:

Sleep ParalysisYoga samadhi
Very common. More than 3 million US cases per year.[6]Legendary, mythical claims and anecdotal stories not well-documented nor verified by independent researchers.
Reproduced, well-documented by independent researchers in various lab experiments.Not reproduced, not well-documented by independent research or lab experiments.
Mechanism fairly well-understood for how and why physical and psychological phenomena occurs during half awake, half asleep state.No “samadhi” or superconscious awareness has been clearly explained in a verifiable, credible way. No scientifically known mechanism for how and why a superconsciousness exists or is actually different from non-supernatural brain states, such as sleep paralysis.
Recorded durations of seconds or minutes.Said to last minutes, hours, days, years, or for eternity (when one reaches godhood or cosmic consciousness). No well-documented cases from independent researchers or experiments.

What can sleep paralysis teach us about yoga traditions?

When we compare sleep paralysis and yoga samadhi experiences we find many similarities. Not all phenomena related to so-called yoga samadhi and sleep paralysis experiences are the same. Paramahansa Yogananda’s “Definite Technique of Attaining Ecstasy” seems to be yoga method to induce sleep paralysis. The ecstasy or experience that Yogananda and yoga tradition may interpret as supreme yoga–union or communion with God–physicians and psychologists may call sleep paralysis.

Have you experienced sleep paralysis? Yoga “samadhi”? What do you think of similarities or differences between the interpretations by yoga tradition?

In Medieval Europe demons called incubus were said to attack women and succubus to attack men, usually sexually. Different cultures interpret differently but usually mythologically the experiences of sleep paralysis, altered awareness, and yoga samadhi.

4  Paramahansa Yogananda, Self-Realization Fellowship Lesson 154. Yogananda refers to “conscious” sleep throughout his yoga lessons, “The soul may use its intuition together with life force released from bodily activities during the relaxation of sleep to project true visions on the screen of the subconscious. Visions may show events to come, as the soul can use its intuitive power to “photograph” future happenings. But a vision does not appear until sufficient energy has been relaxed from the heart and from the ordinary waking consciousness (as in sleep) to project it”, Lesson 73. And, “This detachment of the mind from body consciousness [during yoga meditation] is similar to that experienced in sleep, except that one remains consciously aware”, Summary Lesson.

In the Bhagavad Gita, the Hindu bible, Lord Krishna reveals to his chief-disciple, Arjuna, the Viśvarūpa experience. Arjuna is terrified by Viśvarūpa, said to the universal form of Hindu God(s).

  1. Yes, I have experienced Kanashibari (the Japanese word for it) and many Japanese have — I used to take surveys about it in the school where I taught. Six years ago I wrote a little post on that and astral projection — occurring during Yoga.

    Is altered states labelled as SAMADHI actually kanashibari — probably often. Well done.

  2. David Brooks commented: “I’ve experienced involuntary sleep paralysis since age of 5 (resorted to sleeping curled with knees to chest, head face down-to stop). Had this monthly from late teen till 33 (always scared-thought daemon was after me). In ’93 I was drawn to Yogananda (via “Man’s Eternal Quest). Long story short- sleep paralysis, controlled, becomes ecstasy and a way to observe onesself sleeping. Due to a back injury, I had a haitius from Kriya-a bit of karma, perhaps. Now, nearly 59, I am back on track & hope I can advance with good karma in next life. A taste of, “having a small taste of inexhaustible bliss,” made a devotee out of me. I’ve been interested in Conscious Sleep (samadhi-subconscious state) for years and hope to be blessed to rest as I balance my body mind spirit.”

    @David: Wonder what you do to “control” sleep paralysis? As if you could control it would not be paralysis? It would be voluntary, willed, controlled. I wonder if you’ve seen a doctor about your situation and what medical doc would say. You make much meaning out of what you call sleep paralysis. I’m not convinced you understand what it is.
