I have a question. Do people who have been blind since birth dream and if they do what do they see in there dreams? Do they see images or is it
perhaps just sound.
Good question. Research suggests that people who are blind from birth have no visual component to their dreams. This is in contrast to people who lost
their sight during childhood. In these cases, the individual typically loses the visual elements of their dreams as time progresses. There have been
rare cases where people who were blind from birth described visual elements in their dreams. These elements, however, are believed to be more
metaphorical than literal. This is evidenced by the fact that subjects would describe, for example, silver as "feeling pretty" rather than directly
commenting on how the silver looks visually.
Typically, if a person is born blind, or becomes blind within the first 5-7 years of their life, they will not experience visual aspects in their
dreams and will not undergo Rapid Eye Movement (REM) during their sleep. If a person loses their sight after the age of 7, they will typically retain
the visual elements of their dreams into adulthood. If their sight is lost between the ages of 5 and 7, the individual will typically retain some
visual imagery which will then fade with age.
People who are blind from birth do dream and their dreams are every bit as engaging as sighted individuals. They simply lack a visual element. They do
experience sensations of touch, smell and sound. The following sites should help you if you wish to look into this fascinating subject in greater
