Again, there are cases where the percipient states that a cloud of unreasonable depression fell upon him about the time of his friend's death at a distance, and continued until the actual news arrived; when, instead of becoming intensified, it lifted suddenly. In one or two such cases there was an actual presence or apparition, which seemed to hang about until the news arrived, and then disappeared. Or, on the other hand, there is sometimes a happy vision of the departed preluding the news, as though to prepare the percipient's mind for the shock (_Proceedings_ S.P.R., vol. iii. p. 90 [735 A]). The suggested inference is that in such cases the spirit's attention is more or less continuously directed to the survivor until the news reaches him. This does not, of course, explain how the spirit learns as to the arrival of the news; yet it makes that piece of knowledge seem a less isolated thing. Having thus referred to a number of cases where the apparition shows varying degrees of knowledge or memory, I pass on to the somewhat commoner type, where the apparition lacks the power or the impulse to communicate any message much more definite than that all-important one--of his own continued life and love. These cases, nevertheless, might be subdivided on many lines. Each apparition, even though it be momentary, is a phenomenon complex in more ways than our minds can follow. We must look for some broad line of demarcation, which may apply to a great many different incidents, while continuing to some extent the series which we have already been descending--from knowledge and purpose on the deceased person's part down to vagueness and apparent automatism. Such a division--gradual, indeed, but for that very reason the more instructive--exists between _personal_ and _local_ apparitions; between manifestations plainly intended to impress the minds of certain definite survivors and manifestations in accustomed haunts, some of which, indeed, may be destined to impress survivors, but which degenerate and disintegrate into sights and sounds too meaningless to prove either purpose or intelligence. Let us look, then, for these characteristics, not expecting, of course, that our series will be logically simple; for it must often happen that the personal and local impulses will be indistinguishable, as when the desired percipient is inhabiting the familiar home. But we may begin with some cases where the apparition has shown itself in some scene altogether strange to the deceased person.
