Do People Who Are Blind Experience Dreams?

Blind people dream just like sighted people, but the way they experience those dreams depends on when and how they lost their vision. People who lose sight later in life often retain visual images in dreams, while those born blind tend to dream through other senses like touch, sound, and smell.

How Dreaming Works

Dreaming usually happens during rapid eye movement (REM) sleep, a stage marked by increased brain activity, faster breathing, and temporary muscle relaxation. On average, we spend about two hours per night in REM sleep, with dreams appearing in cycles between other stages.

For sighted people, dreams often feel like watching a vivid movie. While other sensations such as touch or sound can appear, visual imagery dominates. In contrast, blind dreamers often experience a richer mix of sensory input beyond sight.

Dreams in People Who Are Blind

For people blind since birth:

• They don’t “see” images in their dreams.

• Dreams often include heightened senses such as detailed soundscapes, tactile sensations, scents, and spatial awareness.

• The brain constructs a world using non-visual cues, creating a vivid mental environment.

For those who lose sight after age 7:

• They usually retain the ability to see in dreams, similar to sighted individuals.

• Over time, the visual clarity or color in these dreams may fade, especially after years without sight.

For people with late-life blindness:

• Dreams may still include visual elements, but the frequency and vividness can diminish with age.

Emotional Intensity and Nightmares

Research shows that people born blind tend to have more nightmares and emotionally intense dreams than sighted individuals or those who lost vision later. Possible reasons include:

• Higher daily risk: More exposure to threatening or disorienting real-life experiences.

• Memory processing differences: Without visual mental images, the brain may create dream narratives that feel more chaotic or unsettling.

Interestingly, a similar pattern is seen in people born deaf, who also report more frequent nightmares.

The Content of Blind Dreams

While the emotional themes joy, fear, confusion, excitement are similar to those in sighted people’s dreams, the way they’re experienced changes:

• Sighted people: Primarily visual with supplemental sounds, touch, or smells.

• Blind individuals: Often anchored in sound, touch, temperature, smell, and spatial relationships rather than sight.

Takeaway

Blindness doesn’t reduce the richness of dreams it simply changes their form. Dreams remain deeply emotional, immersive experiences, whether they’re built on visual imagery or other sensory details. In many cases, blind individuals may even have a wider sensory range in their dreams than sighted people.
