Charles Bonnet syndrome is visual hallucination due to vision loss. As sight deteriorates, neurons in the visual cortex become hyperactive and fire spontaneously, causing hallucination. These hallucinations are sudden, often appearing, changing, and disappearing without warning. However, it is common for them to disappear when focusing on these images (Sacks, 2013). The hallucinations vary. Some see people or things that are not there; others see real things that are altered in their minds. While some hallucinations seem realist, it is common to see cartoons or animations as well. They can be simple geometrical hallucinations or more complicated facial hallucinations. Many people experience musical hallucinations in which they see music notes
