Okay, I don't know if we have any deaf or blind members, but this is something I was wondering about the other day. When deaf people dream, do their dreams have sound, or only images? And when blind people dream, do they dream only in sound? Because there would be no reason for it to be without sound or images. I assume it would be diffent with people who were born blind or deaf as opposed to people who became blind or deaf in later life. And if they have a lucid dream, could they force it to have sound or image?
