Well?
I don’t have the cite, but I remember reading somewhere that a blind person can see things in dreams, if they used to be able to see, and lost their sight at some point during their life. If they’ve been blind from birth, I’m pretty sure their dreams consist of sounds and smells and such, but no visual images.
So then, my WAG would be that a blind person on acid would see the same things as anyone else, but only if they were sighted for some time, and then became blind due to sickness or an accident or something.
I’m always amazed at the cross-sections of the population we have here at the Dope. Anyone have first-hand experience?
This monograph addresses the question.
About fifteen years ago, I took some LSD with a girl who was congenitally blind.
We mostly listened to music and had the kind of not-quite-joined-up conversations that are common to LSD experiences. (It was her first time.)
She didn’t report “seeing” or visualizing anything unusual (nor would I have expected her to, I suppose.)
One thing I remember her saying a lot was fairly typical: “There’s energy everywhere.”
At one point she kept saying “It’s like wind, but it’s…” and then searching for a word that never came.
We spent a long time playing “feel that?” in a goofy improvised Tai Chi kind of way.
I didn’t grill her about her perceptions, but from what I could gather it was strictly heady/hearing/touch/parasensual-type stuff for her. Laughed her ass off at Nurse With Wound’s Silvie & Babs Hi-Fi Companion.
[/not particularly helpful anecdote.]
IIRC, people who go blind eventually lose their ability to visualize objects. So, it may be that they’d see nothing at all, even in their heads, much like a person who was born blind.

Some do, some don’t.
