blindness

[olivia62]

do people who are blind from birth see anything when they dream.

Basically the answer is no. Seeing is a combination of visual stimulation and organisation of the resulting information in the brain. The link has to be formed and tuned through practice. The dreams of people blind since birth will have the same sort of relation to their waking life as do your own - they will contain the senses they do have; touch, smell, hearing etc

Hmm, I think I'll throw out a few thoughts for you to bounce around.

Firstly, does anyone know of a child who hasn't had a nightmare?

Secondly, what can children blind since birth have a nightmare about?

Thirdly, are nightmares simply composed of variations of previous sensory inputs?

Answers on a postcard please!
