Evidently the more numerous the coincidences, or the dreams which correspond to contemporaneous events, the weaker becomes the theory of _chance_ coincidences. Supposing, then, Lord Brougham's case to have been unique, that not another similar case was known to have occurred, then we should have no particular hesitation in assigning it to the category of chance coincidences; but even then it would be out of the order of _usual_ coincidences both in interest and the number of separate points involved; it would excite special interest, but the reference of it to chance would not be considered unreasonable: if, however, three or four such cases had been reported and discussed in a generation, thoughtful people would begin to inquire if there might not be some relation of sequence, or possibly of cause and effect; but when hundreds of cases have been reported, because they have been systematically sought for--veridical dreams connected with the moment of the death of the agent, with fainting, with trance, with moments of supreme excitement, or of extreme danger, so many different conditions in which by careful observation it is found that such hallucinations and symbols relating to actual contemporaneous occurrences originate and are telepathically transmitted--the matter is then quite removed from the category of chance coincidences, and any attempt to force these cases there to-day denotes either ignorance of established facts or inability to appreciate logical reasoning or even mathematical demonstration. This is all upon the supposition that the case in question was a dream. On the other hand, now place the case where it really belongs as a _waking_ or Borderland _vision_--an event in a class a hundred-fold less numerous than dreams--and in which class corresponding events are at least tenfold _more numerous_, and we see how conspicuously weak is the coincidence theory. Neither need the other horn of the dilemma, namely, Supernaturalism, any longer be taken. A newly recognized method of mental interaction is gradually coming into view; a new principle and law in psychology is being established; and under this law the erratic and discredited facts of history as well as the facts of present observation and experiment are falling into line and becoming intelligible. The new principle or law, as we have seen, is this: Perceptions, of the class which have usually been known as hallucinations, may be originated and transferred _telepathically_; in other words, there is a subliminal self, which, under various conditions on the part of either agent or percipient, or both, may come to the surface and act, impressing the sensitive percipient through the senses, by dreams, visions, and apparitions, as well as through hallucinations of hearing and touch.
