One does not feel as comfortably satisfied that the complicated coincidences in this tale admit of being referred to chance. The odds are enormous against two persons—young men in perfect health, neither of whom before or after this event experienced a sensorial illusion—being the subjects at the same moment of one, their common and only one, which concurred in point of time with an event that it foreshadowed, unless there were some real connexion between the event and the double apparition. And we feel a nascent inclination to inquire whether—in case such instances as the present occasionally recur, and instances like the two before narrated become, when looked for, startlingly multiplied—there exists any known mental or physical principle, by the help of which they may be explained into natural phenomena. The more we look after facts of the above nature, the more urgent becomes the want of such a means of explanation. In every family circle, in every party of men accidentally brought together, you will be sure to hear, if the conversation fall on ghosts and dreams, one or more instances—which the narrators represent as well authenticated—of intimations of the deaths of absent persons conveyed to friends either through an apparition or a dream, or an equivalent unaccountable presentiment. A gentleman—himself of distinguished ability—told me that when he was an undergraduate at Cambridge, he was secretary to a ghost society formed in sportive earnest by some of the cleverest young men of one of the best modern periods of the university. One of the results of their labours was the collection of about a dozen stories of the above description resting upon good evidence. Then there transpire occasionally cases with more curious features still. Not only is the general intimation of an event given, but minute particulars attending it are figured in the dream, or communicated by the ghost. Such tales have sometimes been authenticated in courts of justice. Here is one out of last week’s newspaper:—
