I was thinking about how dreams are just our brains processing visual data from our waking lives. But if someone has never had visual data to begin with, what does a dream actually look like to them? Is it just a radio play with physical sensations? Has there ever been a study on this?
Only a VERY tiny number of people see complete black. Most blind people are more functionally blind than literally so. That is, their vision is so bad that they need some sort of accommodation to adjust. They DO see the world but not in the way that typical vision does.
