[Arthur McGowan]

I seem to remember reading about a man, with a brain injury, who thought his wife was a hat. He could sit and talk with her, and she would converse with him, but he thought she was a hat.

I read the same story, in the book “The Man Who Mistook His Wife for a Hat” by Dr. Oliver Sacks. A very interesting book to say the least.
