I have always been curious about how the mind of a blind person functions while dreaming. Do their dreams consist of nothing but audio? Or do their other senses create somewhat of a picture in their mind. However, does their mind even grasp the concept of "sight" and "picture", or is what they think they can "see" with touch, nothing more than a feeling matched with a name. As most people know you rarely experience much feeling while dreaming. Although maybe heightened senses that the blind experience are able to create touch or feeling while in a dreamlike state?
Any other thoughts on this?
