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?
The vast majority of blind people can see the sun. Blind really means that their vision is so bad that we cannot correct it to anything close to normal and not that they see anything at all. Each experience is different, but likely they can see enough that for purposes of your question they are not blind.
