Visualizing Hallucinations

By Barbara Bray      September 17, 2009 -- 09:23 AM
Neurologist and author Oliver Sacks brings our attention to Charles Bonnett syndrome -- when visually impaired people experience lucid hallucinations. He describes the experiences of his patients in heartwarming detail and walks us through the biology of this under-reported phenomenon.

How does this only happen with visually impaired people? He mentioned that the hearing impaired have hallucinations including music. I find this very interesting and wonder what these hallucinations mean. If you lose one of your senses, then it becomes more heightened and sensitive. Does this happen with people born blind or deaf? As a physician, Dr. Sacks mentioned that 10% of visually impaired see these hallucinations but only 1% acknowledge them because they don't want to appear mad.

Have you had a dream or nightmare that wakes you up? Temporal lobe dreams are more what most of us have that might include people we know.

More on the Charles Bonnett syndrome, Wikipedia reference, and a biography.
