Case No. 9 Miss A. M. H. A very interesting and complex case that is actually an instance in which the music was collectively heard was originally recorded in Robert Owen's Footfalls on the Boundary of Another World (Trubner, 1860). Miss A. M. H., not knowing that her friend "S." was ill, had a "dream" in which she found herself in "S.'s" house. She writes, "There, on the bed, I saw 'S.' as if about to die. I walked up to him, and, filled with hope, said, 'You are not going to die. Be comforted. You will live.' As I spoke I seemed to hear an exquisite strain of music sounding through the room." After "waking," Miss A. M. H. and her mother dispatched a letter to "S." inquiring about his state of health. By return post, it was verified that "S." had been seriously ill. Three years later Miss A. M. H. and her mother chanced to meet "S." in London and thereupon Miss A. M. H. recounted her dream. "S." then claimed that he had tried to encourage his brother to send for her, but that the brother had dissuaded him. During his illness he had seen her phantom and "I would also hear my favorite sonata by Beethoven . . . . You walked up to the bed with a cheerful air, and, while the music which I longed for filled the air, spoke to me encouragingly, saying I should not die." If indeed this was actually a reciprocal telepathically produced apparition, and not an OOBE [Out Of Body Experience] then it goes far beyond the data we presently have for such theories. Such cases of music heard at deathbeds shall be covered extensively in another section of this volume, and have many characteristics of being objective.
