can blind people since birth see in their dreams?

I don't know the answer to this, i asked myself many times about this things, and i am happy with the answer which one of us gave above that people see even they are blind in the dreams. I feel a little sunshine for them. Good luck!

mental reasoning will never be blind, even if genetically inherited, or in the womb. they have similar eye movements, which is just supressed, the REM. rapid eye movements when we sleep and dream, ofcourse when we digest a knowledge in our brains, even if blind, have a vision within the mind. which scientist say, a vision accquired by learning from another senses substituting sight. example, they touch you and they can imagine and figure out what you look like, beautiful or plain shape.. touch an object to see its surface, roughness, smooth etc.. this registered knowledge are stored in a blind persons memory and in dreams are seen in a different visualization, therefore what they touch, hear, feel, taste are expressed although unexplained, they get conclusions of a different meaning from their relied reason of a certain picture of something present in or world.
