For those who are blind, what they see when they dream depends on whether the person was blind at birth or became blind later in life. Those blind from birth may not “see” anything according to how those with vision might define it, but they still experience sensual stimulation of some sort. If their brain has never experienced visual stimulation, there should be no reason for it to manifest in their dreams. It would instead manifest experiences that reflect the person’s stimulatory input. For example, if a person with normal vision dreams about his or her mother, he or she may envision her face, clothing, hair, or facial expressions. A blind person may instead dream about his or her mother’s tone of voice, touch, or even smell.

However, if one formerly had vision but lost it in late childhood or adulthood, evidence does show that they do have some visual dreams. However, those who lost their vision before the age of five don’t have visual dreams, as if they were blind from birth. They may not have retained enough visual imagery to dream visually.
