Um. Yes.
Not everyone who is blind has been blind since birth, not everyone who is deaf has never heard. I once met a man who toured with Jason Mraz, his name Raul Midón both he and his brother were blinded by the baby warmers when they were born. All he ever saw were flashes of light and he explained through telling a story that yes, he dreams. In flashes of color and waves of light. At least that’s all I could hear over the screaming fangirls freaking out over Jason Mraz.
Dreaming is a function of your brain, not your eyes. You feel warmth, touch, pain, wind, everything in your dreams. Why would being without one sense negate them all?
