Do the blind people dream?
Yes, blind people dream.
Dreams are created inside of the brain. Though you may be able to "see" what is happening in your dream, your eyes have absolutely nothing to do with that. As to what you dream, believe it or not, blind people are no different from sighted people. They still dream just as vivid, the contents of the dreams are no different.
What do blind people dream of if they never saw anything in their life and do they see color or just black?
It looks like blind people have dreams that involve their other senses. They also see many things that we ourselves have never seen before. Like when we dream of a new invention or a person we've never met or a place we've never seen or been to. We rarely have these dreams because we have the ability to see but if we didn't, like people who are blind, we would be using the imaginative part…
There was no speech about you having a dream. He did write a speech about having a dream of his own called "I have a dream". This was based on his hope of equality for all people regardless of color. He wanted a world in which people were color blind and responsible and honest citizens regardless of their color or heritage.
Some people have eye problems that cause colorblindness and if they have been color blind since they were born they have never seen any other colors. People dream about only past experiences they have had and in their dreams they still have sound, sight, feeling, and taste in their dreams but their dreams would be different from most humans because they wouldn't have color in their dreams.
Completely blind people do not see anything at all from the outside world. Some who are legally blind can still distinguish light from dark. Some people say blind people only see darkness, but it isn't confirmed only because people who have seen color all their life who become blind say they only see black.
