(Assuming they were always blind)
I have read, somewhere (sorry, it was years ago, so I can’t provide a quote or link), that blind people dream about feelings and about emotional states… but, of course, no visual content whatsoever…
Cecil Adams, the All Knowing One, forsaw that someday you would ask this question, and so provided an answer, from More of the Straight Dope: What are the dreams of the blind like?.
whitetho, good on ya! Maybe that’s where I read it!
Along, the same lines, what about deaf people? Do they dream normally minus sounds? In sign language perhaps?
yes. (my brother is deaf)
I believe that my puppy dreams smells. Often at night, after she’s gone to bed, I’ll catch her curled up but sniffing loudly, occasonally letting out a little bark.
[hijack]My dog, it seems, often dreams of his mother. I catch him nodding off, and making sucking sounds. Like his mother is feeding him.[/hijack]
The sight impaired (along with the hearing impaired, people with an unusually poor sense of smell, those of us with hitchhiker’s thumb, Pepsi drinkers, left handers, heterochromic glam rockers, and everyone else) dream about sex.
I’m not vision/hearing impaired, but usually when I dream, if someone says something, I don’t necessarily have to hear them say it. I just sort of know what they want me to know automatically. (Not all the time, but some of the time.) It might be the same way sometimes with deaf people; they just know, without needing to see sign language.
