The Book of Dreams and Ghosts
Andrew Lang80"So vivid was my remembrance of the features of the soldier, that some months after the occurrence [of the vision] when I called with my husband at a house where there was a portrait of him, I stepped before it and said, 'Why, look! there is the General!' And sure enough it was." Mrs. M. had not heard that the portrait was in the room where she saw it. Mr. M. writes that he took her to the house where he knew it to be without telling her of its existence. Mrs. M. turned pale when she saw it. Mr. M. knew the sad old story, but had kept it to himself. The family in which the disgrace occurred, in 1847 or 1848, were his relations. {78} This vision was a veracious hallucination; it gave intelligence not otherwise known to Mrs. M., and capable of confirmation, therefore the appearances would be called "ghosts". The majority of people do not believe in the truth of any such stories of veracious hallucinations, just as they do not believe in veracious dreams. Mr. Galton, out of all his packets of reports of hallucinations, does not even allude to a veracious example, whether he has records of such a thing or not. Such reports, however, are ghost stories, "which we now proceed," or continue, "to narrate". The reader will do well to remember that while everything ghostly, and not to be explained by known physical facts, is in the view of science a hallucination, every hallucination is not a ghost for the purposes of story-telling. The hallucination must, for story-telling purposes, be veracious.
