Hi nomanshake,
I don't know how much this will help, since I was never completely blind. But I am legally blind, and before my eyes were able to be corrected with special lenses (even contacts, now

) I dreamed. But since I had never seen things very well at all, yes--I would say that many of my dreams were "blurrier" than they were after I could see. But also, some dreams were extremely beautiful and vivid. And, as I later found out, quite accurate in "visual" detail--if not enhanced. Does that make any sense?
My son-in-law's grandmother is completely blind, but since childhood--in other words, there was a time when she could see. I know she dreams, because she mentioned it one time to me. But I never thought to ask her about the visual details at the time, because the story in the dream was such a hoot! When I visit with her again, I will ask her.
I'd like to say that I wish I could be of more help, but in this particular case, I guess I'll just be happy that this is all I can offer---

.
InPeace,
InLove
