Dominic Ffytche of the Institute of Psychiatry in London told the British Association that 60% of patients suffering from common forms of vision loss had reported hallucinations involving faces.
“You would think it would be of a familiar face, perhaps a relative or someone famous. But they are not. They are often described as being grotesque,” he said. “
About 40% of people with eye disease hallucinate figures in costumes. These could be Edwardian costumes, knights in shining armour, military uniforms, Napoleonic uniforms, first world war uniforms.”
This happens, Ffytche told the Guardian, even in patients who have had both eyes removed.
Sight is certainly not required for a ghostly hallucination.
