text: do the blind dream?   yes, blind people do dream. what they see in their dreams depends on how much they could ever see. if someone has been totally blind since birth, they only have auditory dreams. if someone  has had a measure of sight, then that person dreams with that measure of sight. those individuials who have had some sight before they went blind can dream as though they can see, colors included.   in all fairness, one should first look at what a dream is.. really.. this must be understood before the question could be fully answered. the word "dream" has four interrelated meanings that follow one from another. when we put them altogether, we know what a dream is.   first, a "dream" is a form of thinking that occurs when (a) there is a certain, as yet undetermined, minimal level of brain activation, and (b) external stimuli are blocked from entry into the mind, and (c) the system we call the "self system" (the "i," the "me") is shut down.  second, a "dream" is something we "experience" because the thinking is very real and makes use of our senses -- especially seeing and hearing; because usually we are the main actor; and because a dream is sometimes very emotional (but not always).   third, a "dream" is what we remember in the morning, so it is "a memory" of the dreaming experience.   fourth, a "dream" can also mean the spoken or written "report" we give to others about that experience, which is the only way anyone else can ever know about another person's dreams (because they can't be seen by others or told about by us while they are happening).   so....in summation (keeping in mind what dreams are),  there are no visual images in the dreams of those born without any ability to experience visual imagery in waking life.   individuals who become blind before the age of five seldom experience visual imagery in their dreams, there has been  reports some visual imagery in six schoolchildren who lost their sight before age five.   those who become sightless between the ages of five and seven may or may not retain some visual imagery.   most people who lost their vision after age seven continue to experience at least some visual imagery, although its frequency and clarity often fade with time.
