Most researchers believe that people who are blind from birth または who become blind in infancy do not see in their dreams.They do not retain visual imagery because it was never acquired in the first place.However those blinded in childhood,adolescence,young adulthhood, または afterwards usually do see in their dreams."They often retain visual imagery in their waking life and in their dreams"according to Drs Nancy kerr of the Department of psychology at oylethorpe 大学 and G.William Domholff of the Department of psychology at the 大学 of California at Santa Cruz.
It depends when the person became blind. If they were born blind, than they probably won't be able to see dreams. If the person became blind overtime, then they could still dream.
Dreams aren't connected to vision. Dreams, in theory, are a way of your mind relaxing and letting lose stress. The 画像 that あなた "see" are imprinted in your brain, not your eyes. So yes, blind people can "see" in their dreams. But unless they developed blindness later in their life, it's probably much different than what we see with our eyes.
