I remember most of my own dreams for their visual component, much less for the aural parts, and I don’t recall ever tasting or smelling anything. I wondered how dreams for the blind might be? Do sight-impaired people usually dream with the senses of their real lives, or do they “see” anything?
Cecil has answered this question.
It’s worth noting that only 2% of all blind people are blind from birth. The vast majority of the blind had vision earlier in life (many of them until they became senior citizens) and so will retain imagery in their dreams.
Most of your dreams are concerned with situations and emotions. These are based around your environment which, for most of us, is described by visual information, as humans have adapted to rely on sight as the primary means of learning about their environment.
I would imagine that blind people would dream about situations and emotions that are based around the environment in which they live: that of touch, taste, smell, and hearing.
They would dream about similar things, they would just have a different way of relating to them
