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?


Here is a study i found titled
Mental Imagery in Dreams of Congenitally Blind People

Just fyi: MDPI-published research does not have a good reputation.
