A blind person's dreams consist of input from all senses except sight.
The first thing I thought about was how could they actually realise they were dreaming?
They would have to have a dreamsign that was a smell or taste or noise or feeling.
Just thinking about it is kinda wierd.

Once lucid though, they still don't have any perceptual experience to work with, so their lucid dream would still surely only consist of the four other senses that they possess.

Pretty crazy to think about, imagine if you could see in your lucid dreams but not while awake!

Interesting question!
