How the blind dream would really depend on when they lost sight. If a person was never able to see, then the dream would definitely be quite different. However if a person lost sight recently, I imagine dreams would be fairly normal.
Yes, blind people still dream. Dreaming is a function of the brain not a function of the eyes. All people require REM sleep, or rapid eye movement sleep where dreaming occurs. I know for some that the dreams are different than a sighted person's dreams. Some blind people who have lost their sight have dreams very similar to a sighted person's dreams. A friend of mine who blind from birth had dreams that were a little different than mine as a sighted person. He described people and things in his dreams much the same way he 'saw' them when he was awake. He described the feel of things rather than the look of them. Not being blind myself, it's hard to explain the way he did, but he still had dreams.
I am sure that the blind do dream, but it would be interesting to see if the nature of their dreams are changed or impacted by blindness. It would be interesting to see if there is a difference between those who are born blind and those who are blinded during their life from an accident or disease. Would never having perceived objects change the nature of dreams? A fascinating question.
Wow, I never thought about it. I would like to think "yes" though. Given that dreams are created by the brain, one would think that people without sight would dream. Perhaps a different question would be: what do people who are blind dream about?
I would guess that even though some may never have seen an apple (for example) their mind would still be able to create a picture of it based upon their own perceptions of what the object "looks" like.
This is an intriguing question. I assume that blind people dream (especially if they once had sight), and apparently this is indeed the case. Here are some links that may interest you:

My uncle lost his eyesight nearly 50 years ago when he was in his 30's. He still dreams with full visuals, and from what he describes, his dreams sound like everyone else's. I imagine that the fact that he was a sighted person during his formative years matters.
You might be interested in Robert Kurson's book Crashing Through, in which he writes about Mike May, who loses, and then, years later, regains his eyesight.
