Charles Bonnet Syndrome

Visual hallucinations are usually associated with schizophrenia or drug use, but there is a condition named Charles Bonnet Syndrome, which can cause a healthy person to experience visual hallucinations. It isn’t caused by any mental illness but caused by vision loss. One-third of the people whose eyesight starts deteriorating, experience vivid, cartoonish visual hallucinations. Victims mostly tend to see weird creatures and animals. The reason behind this is that the brain always expects sensory input from the eyes, but when it receives nothing due to vision loss; it creates its own inputs.
