what about people blind from birth?
hmmm?

I will look it up!

edit:

Research suggests 4 findings on 'blind dreams' apparently according to an online study I found.

1. There are no visual images in the dreams of those born without any ability to experience visual imagery in waking life.

2. Individuals who become blind before the age of five seldom experience visual imagery in their dreams, although Deutsch (1928) reports some visual imagery in six schoolchildren who lost their sight before age five.

3. Those who become sightless between the ages of five and seven may or may not retain some visual imagery.

4. 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.

The study also showed the following -

Findings on non-visual sensory references, the percentage of taste/smell/touch sensations was very high in the dream reports of participants who had little or no visual imagery. For the four participants who had no visual imagery in 13 or more sensory references (participants 11, 7, 10, and 2), 55% of the sensory references were taste/smell/touch and 45% were auditory. For participant 14, the 45-year-old male totally blind since age 28, 22 of his 34 sensory references (65%) were in the taste/smell/touch category, as compared to the 9% for visual references reported earlier. The sensations in such dreams were very strong. The participants "felt" the warmth of the sun, the texture of a coat, the edge of a knife, the slope of the ground, vibrations, snow, or the soft fur of a dog. They "smelled" fire, tobacco, aftershave lotion, fresh air, food, or coffee. They noted the "taste" of a cigar, a cup of coffee, or an orange. These dream sensations seemed to reflect their use of or pleasure in these sense modalities in waking life.
