Barbara -An "auditory dream" is a dream with only sounds and no images. Basically, the dreams of someone who's been blind from birth are just like the dreams that you have - just without the pictures.People's dreams are based on the things they experience in their lives. That is to say that in a way, our dreams are based on our memories. So a person who has never experienced "seeing" will not dream using sight. This is just like how you do not dream with sonar images, as humans can not use sonar. Perhaps animals like bats, if they do dream (I don't know if they do or not) dream in sonar. ;)As for your last question, the images that we see in our dreams aren't real light - they're signals within our brains that we experience the same way we would experience light. So light is neither stored nor produced. You could say that our minds "play tricks on us" to make us think we're seeing light when it's not really there.-Tamara
