What research shows
Affects around 8% of the general population at least once, higher in students and shift workers. During REM the body is atonic by design; paralysis is that state persisting a few seconds into wakefulness.

Dreaming about paralysis
Dreaming about paralysis is traditionally read as not a dream at all in the strict sense — sleep paralysis happens on the edge of waking, and the mind supplies a story for a body that will not move. No survey has measured how often this one occurs, so we give the reading without a frequency — only 19 of the dream themes here have a published figure at all.
The psychological reading
The sensed presence, chest pressure and inability to speak are the three classic features, and they recur across every culture studied — with different names attached. The Old Hag, the kanashibari, the pisadeira are the same experience.
When it turns up
Why this dream arrives when it does
Sleep paralysis is not a dream in the strict sense: it happens on the edge of waking, when the muscle inhibition of REM persists while awareness returns. The mind then supplies an explanation for the pressure and immobility, which is where the figures come from.

The version matters
Different ways this dream shows up
The version carries most of the information.
Knowing what it is reduces the fear substantially, which is one of the few places where information about a sleep phenomenon changes the phenomenon.
Being unable to move or speak
The core experience. It lasts seconds to a couple of minutes and ends on its own, always.
A presence in the room
Reported by close to half of people at some point. The sense arrives without an image and is extremely convincing.
Pressure on the chest
A standard feature, and the origin of the word nightmare — the mare was the creature that sat on the sleeper.
Hearing voices or buzzing
Hypnagogic sounds. They are ordinary in this state and not a symptom of anything by themselves.
A dream within a dream
A searched variant: false awakenings often accompany paralysis, and people report waking several times.
Trying to wake someone beside you
Commonly attempted and rarely successful, since the body is still immobile. Small movements — fingers, eyes — usually break it fastest.
Commonly claimed, and wrong
What this dream does not mean
This is not possession, spiritual attack or a warning, and the cross-cultural consistency of the experience is the strongest evidence for that: the same episode appears as the mare in Europe, the jinn in Islamic accounts, the old hag in Newfoundland and kanashibari in Japan.

Questions about this dream
What is sleep paralysis?
REM muscle inhibition persisting as you wake. You are conscious and cannot move, and it ends by itself within a couple of minutes.
How do I stop it?
Regular sleep timing and enough sleep reduce frequency. Sleeping on your back makes it more likely for many people.
Is it dangerous?
No. It is frightening and harmless. Frequent episodes with daytime sleepiness are worth mentioning to a doctor.
