Blind dreams?

Not gonna lie, this is one that made me go "hmmnn?". I'm curious now too!

 

This answer from the link below seems to make sense. You dream with whatever visual material you've ever had.

" Yes, blind people do dream. What they see in their dreams depends on how much they could ever see. If someone has been totally blind since birth, they only have auditory dreams. If someone such as I, has had a measure of sight, then that person dreams with that measure of sight. I still dream as though I can see, colors included. For people I've met since, their faces are just blurs or how I imagine they look. To me, someone like my mother looks forever 30. "

Also, do deaf people dream with sound? Quote below...

"Those who are born blind or become blind before the age of five do not see in their dreams. Nevertheless, their dreams are just as rich in narrative and detail as in sighted people. If one's sight is lost after the age of seven, dreams will still brim with visual imagery. A grey area exists between five and seven years.
Interestingly, those rapid eye movements (REMs) signifying that a dream is in progress do not occur, or occur very weakly, for those born blind or blinded before five.

How about congenitally deaf people? It appears that they may dream in sign language! Their dreams are also more colorful than those of people with normal hearing."
