It would naturally be expected that the nature and subject-matter of the more frequent types of coincidences and presentiments would throw some light upon their origin, and would in some measure reinforce the general position above taken. We should expect that such coincidences would relate to persons and affairs that are frequently in our thoughts, and that similarities of thought and presentiments based upon them should occur among persons intimately acquainted with one another's thought-habits, at least in regard to that line of thought to which the coincidence relates; these expectations are fairly well borne out by the facts. It is a commonplace observation that presentiments and unusual psychic experiences most frequently relate to those who are dear to us, or in whom we have a momentarily strong interest; that they deal with events which we have anxiously dreaded or desired, or with matters over which we have puzzled or worried; and again, that they occur under conditions of emotional strain, excitement, or anxiety. In brief, they deal with what is frequently in our minds or what more or less unconsciously furnishes the general emotional and intellectual background which gives character to our mood and to our associations of ideas. I need hardly add that it is the more successful and striking coincidences that we remember and record, and the others that are quickly forgotten. Moreover, so large a share of mental operations of the type in question takes place in the region of the subconscious, that our recollection of what has occupied our thoughts is by no means a final authority. Occasionally we detect these subconscious similarities of mental operations, when after a silence the same question or thought shapes itself on the lips of two speakers at the same time; and here again, are not many of those who give utterance to the same thoughts, or finish one another's sentences, intimate companions in the walks of life? Is it strange that in the daily intercourse with a congenial spirit, they should have absorbed enough of one another's mental processes to anticipate, now and then, a step in their association of ideas?
