The Book of Dreams and Ghosts

So far Mr. Galton would go, but mark what follows! Everybody allows the existence of dreams, but comparatively few believe in dream stories of veracious dreams. So every scientific man believes in hallucinations, {68} but few believe in veracious hallucinations. A veracious hallucination is, for our purpose, one which communicates (as veracious dreams do) information not otherwise known, or, at least, not known to the knower to be known. The communication of the knowledge may be done by audible words, with or without an actual apparition, or with an apparition, by words or gestures. Again, if a hallucination of Jones's presence tallies with a great crisis in Jones's life, or with his death, the hallucination is so far veracious in that, at least, it does not seem meaningless. Or if Jones's appearance has some unwonted feature not known to the seer, but afterwards proved to be correct in fact, that is veracious. Next, if several persons successively in the same place, or simultaneously, have a similar hallucination not to be accounted for physically, that is, if not a veracious, a curious hallucination. Once more, if a hallucinatory figure is afterwards recognised in a living person previously unknown, or a portrait previously unseen, that (if the recognition be genuine) is a veracious hallucination. The vulgar call it a wraith of the living, or a ghost of the dead. Here follow two cases. The first, The Family Coach, {69a} gave no verified intelligence, and would be styled a "subjective hallucination". The second contributed knowledge of facts not previously known to the witness, and so the vulgar would call it a ghost. Both appearances were very rich and full of complicated detail. Indeed, any ghost that wears clothes is a puzzle. Nobody but savages thinks that clothes have ghosts, but Tom Sawyer conjectures that ghosts' clothes "are made of ghost stuff".
