Abstract
The patient was a 60 year old man who complained that he had begun to see ghosts frequently. He noted difficulty in writing when he was 57 years old because he could not remember Japanese characters well, and this was accompanied by severe insomnia. He frequently had VH both during the day and at night. Two typical hallucinations are described below.
