Publisher's Synopsis
Now, the ghostly is nothing but the experience, when men are awake, or apparently awake, of the every-night phenomena of dreaming. The vision of the absent seen by a waking, or apparently waking, man is called "a wraith"; the waking, or apparently waking, vision of the dead is called "a ghost". Yet, as St. Augustine says, the absent man, or the dead man, may know no more of the vision, and may have no more to do with causing it, than have the absent or the dead whom we are perfectly accustomed to see in our dreams. Moreover, the comparatively rare cases in which two or more waking people are alleged to have seen the same "ghost," simultaneously or in succession, have their parallel in sleep, where two or more persons simultaneously dream the same dream. Of this curious fact let us give one example: the names only are altered.
