Course they do! some people who can see have less imagination...

Dreaming: An Introduction to the Science of Sleep (Oxford). People who are born without sight, Hobson says, never experience any visual images whatever, asleep or awake. This is because their visual systems never had the contact with the “outer” world necessary to develop he neurological “code” to handle visual signals; hence, they cannot “call up” images. People without sight, though, do dream: They use other senses in their dreams, Hobson says, such as bodily sensations and the sense of body position.”

What do blind people see when they dream? Dreams of people who have memory of sight tend to be based on what they remember, says Jim Sanders, vice-president of client services and technology for the Canadian Institute for the Blind, who’s often discussed the subject. Dreams of those who’ve never seen are based on emotions and things they’ve touched and imagined.”

Yes.

Most researchers believe that people who are blind from birth or who become blind in infancy do not see in their dreams. They do not retain visual imagery because it was never acquired in the first place.

However, those blinded in childhood, adolescence, young adulthood, or afterwards usually do see in their dreams. "They often retain visual imagery in their waking life and in their dreams," according to Drs Nancy Kerr of the Department of Psychology at Oglethorpe University and G. William Domhoff of the Department of Psychology at the University of California at Santa Cruz.

They write in the December 2004 issue of Dreaming that "individuals blinded before the age of about five report no visual imagery in dreams as adults, whereas those blinded after about the age of seven are likely to retain visual imagery in dreaming".

This conclusion is based upon four sleep laboratory studies conducted between 1966 and 1999. According to the Royal National Institute of the Blind in London: "Dreams are experienced in the same way as life is lived. If someone loses their sight, they will dream of events during the days when sight was available in visual terms. If dreams are about recent events when sight was not used, sensations will be in terms of sound, smell, texture, and so on." A person dreams as they live.
