The Book of Dreams and Ghosts

PREFACE TO THE FIRST EDITION The chief purpose of this book is, if fortune helps, to entertain people interested in the kind of narratives here collected. For the sake of orderly arrangement, the stories are classed in different grades, as they advance from the normal and familiar to the undeniably startling. At the same time an account of the current theories of Apparitions is offered, in language as free from technicalities as possible. According to modern opinion every "ghost" is a "hallucination," a false perception, the perception of something which is not present. It has not been thought necessary to discuss the psychological and physiological processes involved in perception, real or false. Every "hallucination" is a perception, "as good and true a sensation as if there were a real object there. The object happens not to be there, that is all." {0a} We are not here concerned with the visions of insanity, delirium, drugs, drink, remorse, or anxiety, but with "sporadic cases of hallucination, visiting people only once in a lifetime, which seems to be by far the most frequent type". "These," says Mr. James, "are on any theory hard to understand in detail. They are often extraordinarily complete; and the fact that many of them are reported as veridical, that is, as coinciding with real events, such as accidents, deaths, etc., of the persons seen, is an additional complication of the phenomenon." {0b} A ghost, if seen, is undeniably so far a "hallucination" that it gives the impression of the presence of a real person, in flesh, blood, and usually clothes. No such person in flesh, blood, and clothes, is actually there. So far, at least, every ghost is a hallucination, "that" in the language of Captain Cuttle, "you may lay to," without offending science, religion, or common-sense. And that, in brief, is the modern doctrine of ghosts.
