Dreaming of not being able to breathe — what does it mean?

What does it mean to dream you cannot breathe?

The air will not come. You draw in and it is as though nothing follows, and the panic rises faster than in any other dream. Many wake abruptly from this one, with a racing heart and a breath that has to be gathered back.

This dream deserves to be handled in two steps. First the physical, because sometimes that is what is going on. Then the symbolic, which is where most people start.

When the body is part of the picture

Breathing during sleep

Breathing changes over the course of the night, and during REM sleep it is shallower and more irregular than otherwise. Dreams can absorb what the body is actually doing, and a breath that stumbles can become a dream of getting no air.

When it is worth having checked

If the dream comes often, and you wake with headaches, a dry mouth or unusual daytime tiredness, it is worth raising with a doctor. Pauses in breathing during sleep are common, they are very treatable, and they are something few people notice in themselves.

This is not meant to frighten. The great majority of people who have had this dream a few times have nothing wrong with them. But it is the one dream type where a physical explanation should be ruled out before it is read symbolically.

Once the physical is settled

If the breathing is fine, the image remains. Getting no air is one of the most direct expressions of a situation without a way out, and the dream often uses it quite literally.

What closed off the air

If you were underwater: Sits close to dreams of drowning, and often concerns something that has grown larger than you can manage.

If it was smoke or fire: Can mirror an acute strain rather than a prolonged one, since fire in dreams is more often tied to something happening now.

If something or someone held you down: Tends to point to a relationship or an obligation that feels confining.

If nothing closed it off and the air simply failed to come: The most common variant, and the one that most often has a physical side. The absence of a cause within the dream is itself a piece of information.

If you could breathe again before waking: Many describe a relief that stays with them through the day. The turn is worth noting, particularly if the dream recurs.

The dream that comes in tight periods

Some recognise the dream from one particular phase of life and find it disappears once the phase is over. Others have it only a handful of times. Isolated episodes without other complaints usually say little beyond that the night was restless.

With no physical explanation, the dream tends to appear in phases where something is tightening: work with no room in it, finances with no slack, a relationship where you do not feel free. Our language uses the same images while awake — we speak of breathing out, and of having no air.

If the dream or this article brings up strong feelings, talk to someone you trust.
