Hallucinations and dreams are imaginations gone wild. From the book … Hallucinations … author … Oliver Sacks When Rosalie—the very old blind lady I described in the chapter on Charles Bonnet Syndrome—became ill and thought she was dying, she had visions of her mother and heard her mother’s voice welcoming her into heaven. These hallucinations were completely different in character from her usual CBS hallucinations—they were multisensory, personal, addressed to her, and steeped in warmth and tenderness. Her CBS hallucinations, by contrast, had no apparent relation to her and aroused no emotion. I have known other patients (who did not have CBS or any other special condition facilitating hallucinations) to have similar deathbed hallucinations—sometimes the first and last hallucinations in their lives.
