What is sleep paralysis?
Sleep paralysis happens when a person becomes aware while the body is still in the stillness that accompanies dreaming. The eyes open and breathing continues, but the limbs and voice do not respond. It lasts from a few seconds to a couple of minutes and ends by itself or at a touch.
Many episodes come with something more: a sense that someone is in the room, pressure on the chest, a shadowy figure, humming or buzzing, or a feeling of floating out of the body. These are dream elements arriving while the eyes are open. The experience is frightening the first time and harmless.
On the tree of the hidden arts: Astral projection.
What sets Sleep Paralysis apart
Allan Cheyne's surveys sort what people report into three clusters. The intruder is a felt presence, with footsteps or a shape at the edge of sight. The incubus is pressure on the chest and trouble drawing breath, the old nightmare proper. The third is bodily: floating, flying, spinning and leaving the body, which is the cluster writers on projection have seized on. The first two tend to come together, with fear; the bodily kind stands more apart and is the one people most often describe as pleasant.
- Mechanism: the muscle stillness of dream sleep persisting into wakefulness
- Duration: seconds to a couple of minutes
- How common: about 8 in 100 people at least once; more among students
- Three clusters: intruder, incubus, and unusual bodily experiences, in Cheyne's studies
- Folk names: the Old Hag in Newfoundland, kanashibari in Japan, the mare in old English
- Painted: Henry Fuseli, The Nightmare, 1781
Often mistaken for something else: A night terror happens in deep sleep, with thrashing and no memory afterwards; in sleep paralysis the person is awake, still and remembers everything.
The story behind Sleep Paralysis
Folklore explained it long before medicine did. The mare of the word nightmare was a spirit that pressed on sleepers, and comparable beings include the Old Hag of Newfoundland and the Japanese kanashibari. The term sleep paralysis entered medicine in the 1920s. David Hufford's study of 1982 showed that the experience is the same across cultures, and Allan Cheyne later sorted its hallucinations into three groups.
Why Sleep Paralysis matters
Many accounts of night visitors, and many first attempts at leaving the body, turn out to be this, and knowing it removes most of the fear.
How to read Sleep Paralysis
Writers on projection treat the paralysed moment as a threshold; the house treats it as a normal overlap of sleep and waking that passes.
Sleep Paralysis in practice: an example
A student wakes at dawn unable to move, sure that someone is standing by the door, and a minute later can sit up in an empty room.
Where readings of Sleep Paralysis go wrong
Sleep Paralysis is harmless and brief. Episodes that are frequent, or that come with sleepiness in the day, are worth raising with a doctor.

Common questions
What is sleep paralysis?
It is waking up, or starting to fall asleep, while the body is still immobilised as it is during dreaming. The person is aware but cannot move or speak for a short time.
Is sleep paralysis dangerous?
No. Breathing continues normally and the episode ends within seconds or minutes. It can be very frightening, but it does not harm the body.
Why do people see figures during sleep paralysis?
Because part of the dreaming brain is still active. Dream imagery and a strong sense of presence appear in the real bedroom, which is why so many cultures tell of a night visitor.
