How about this scenario I saw on a programme about near death experiences
A woman was born blind and had no conception of images, colours or the world around her--other than what she gathered via her other senses
She had an operation and declared clinically dead for some 5 minutes or so, but revived
When better she said she saw these wonderful shapes in a beautiful place and saw people she could describe. Relatives identified these people as those who had died
Where do you think the images came from?
She had never never seen anything before her ND experience
