To understand what blind people experience in their dreams, we must distinguish the experiences of those who were blind at birth from those that became blind later in life. Humans born without sight are not able to collect visual experiences so they do not dream in pictures. People that lose vision later in life had the ability to collect many visual experiences that can appear in their dreams and in a manner very similar to a sighted person.
People have been studying the mechanics of dreams for thousands of years and still not much is known about them, but one thing is certain - we all dream. This means that from about the time of birth we begin our lifelong collection of experiences and memories that later appear during our sleep. Dreams are an inherent part of our lives and they appear in distinct ways depending on the type of senses we use.
