Yup, blind people do have dreams. In fact, everybody dreams. If you didn’t dream, you’d go absolutely insane. It’s something your mind needs. I don’t think people who have been blind from birth dream -images,- because there have been people who are blind from birth, get an operation to gain sight, and are unable to function with that sight because they haven’t developed it. They do hear and feel in their dreams though, just as we do.
