From the Ted Talk by Elizabeth Cox: What causes hallucinations?
Unscramble the Blue Letters
When the vauisl cortex is deprived of input from the eyes, even temporarily, the brain still tries to create a cnehroet picture, but the limits of its abilities become a lot more obiovus. The full-blown hallucinations of Charles Bonnet Syndrome are one example. Because Charles bonent Syndrome only ouccrs in ppoele who had normal vision and then lost their sight, not those who were born blind, scientists think the brain uses remembered images to compensate for the lack of new visual ipunt. And the same is true for other seness. People with hearing loss often hallucinate music or voices, sometimes as elaborate as the cacophony of an entire marching band.

Original Text
When the visual cortex is deprived of input from the eyes, even temporarily, the brain still tries to create a coherent picture, but the limits of its abilities become a lot more obvious. The full-blown hallucinations of Charles Bonnet Syndrome are one example. Because Charles Bonnet Syndrome only occurs in people who had normal vision and then lost their sight, not those who were born blind, scientists think the brain uses remembered images to compensate for the lack of new visual input. And the same is true for other senses. People with hearing loss often hallucinate music or voices, sometimes as elaborate as the cacophony of an entire marching band.
