By contrast, people who become blind as children or adults do have visual dreams, but their dream images depict the world as it appeared around them at the time they lost their sight.
Charles Crawford, executive director of the American Council of the Blind had this to say:
“A blind person’s brain might combine sensory information into a representational image of an object, but that image would bear little resemblance to the object itself”. I lost my vision by the time I was 22. When I have visual dreams, the images are of the world before the 1960’s.”
