Sometimes, she said, before the people come on, she may hallucinate pink and blue squares on the floor, which seem to go up to the ceiling.
I said, "Is this like a dream?" And she said, "No, it's not like a dream. It's like a movie." She said, "It's got color. It's got motion.
But it's completely silent, like a silent movie." And she said that it's a rather boring movie.
She said, "All these people with Eastern dress, walking up and down, very repetitive, very limited."
And she has a sense of humor. She knew it was a hallucination. But she was frightened. She'd lived 95 years and she'd never had a hallucination before.
She said that the hallucinations were unrelated to anything she was thinking or feeling or doing, that they seemed to come on by themselves, or disappear.
She had no control over them. She said she didn't recognize any of the people or places in the hallucinations.
And none of the people or the animals, well, they all seemed oblivious of her.
And she didn't know what was going on. She wondered if she was going mad or losing her mind.
Well, I examined her carefully. She was a bright old lady, perfectly sane. She had no medical problems.
She wasn't on any medications which could produce hallucinations. But she was blind.
And I then said to her, "I think I know what you have." I said, "There is a special form of visual hallucination which may go with deteriorating vision or blindness.
This was originally described," I said, "right back in the 18th century, by a man called Charles Bonnet.
And you have Charles Bonnet syndrome. There is nothing wrong with your brain. There is nothing wrong with your mind. You have Charles Bonnet syndrome."
你得的就是邦納癥候群(Charles Bonnet syndrome)群。問題既不在你的大腦，也不在你的意識，你只是得了這種邦納癥候。”
And she was very relieved at this, that there was nothing seriously the matter, and also rather curious.
She said, "Who is this Charles Bonnet?" She said, "Did he have them himself?"
And she said, "Tell all the nurses that I have Charles Bonnet syndrome."
"I'm not crazy. I'm not demented. I have Charles Bonnet syndrome." Well, so I did tell the nurses.
