The ancient explanation of such events consisted in a reference to the Deity, who was supposed to address his favorites through the medium of dreams. The modern skeptical explanation views all such revelations as mere accidents. Among the myriads of dreamers, say the “five-sense philosophers,” the infinite variety of combinations which disturb the brain during sleep, cannot fail to produce occasionally such coincidences. When these are of a striking character, the seemingly prophetic vision is remembered, but the cases of discrepancies between vision and result are not recorded, and are soon forgotten. This opinion may very probably be correct in the vast majority of instances; but, if so, we are not in a position to assert any scientific demonstration of the fact. There is, moreover, so far as the ancient religious view is concerned, a certain transcendental sense in which it is true that God may guide his creatures through the agency of dreams, as well as in a thousand other different ways; but this metaphysical process we can no more comprehend than we can understand or explain the interaction of mind and matter in the brain. The psycho-physiologist must content himself, at present, with the attempt to show that it may not be incompatible with natural law for coming events to cast their shadows before them through the forms of a dream. The following observations lend color to such a possibility. The extraordinary susceptibility of the brain during certain conditions of sleep has already been noted as a cause for the superior vividness of coloring and intensity of action which sometimes characterizes our dreams. In this respect a slightly morbid condition of the brain, comparable to the effects of hasheesh, probably exists. In such cases the brain may be disturbed to a degree sufficient for the awakening of consciousness by causes that would ordinarily be powerless to reveal themselves. Recording his experience of an earthquake at Lesina, in the night of Sept. 8, 1884, Buschick states, in the Journal of the Austrian Meteorological Society, that a few seconds before the shock he was awakened with a feeling of strange discomfort and apprehension. Once before, on a similar occasion, he had been in like manner aroused from sleep just before the commencement of an earthquake, probably by a feeble and ordinarily imperceptible agitation of the soil. At a time when I was for many months severely overtasked, I always woke up in the night whenever about to receive a call to a patient. Before the sound of footsteps became audible on the sidewalk, I would wake. Presently some one would be heard, approaching the house, and then the doorbell would ring. So often was this experience repeated, that I learned to expect a summons whenever awakened during the night. Gradually, however, as my health improved with rest, this morbid excitability disappeared, and has never been renewed. It seems probable
