Among repeated apparitions this case at present stands almost alone; its parallels will be found when we come to deal with the persistent "controls," or alleged communicating spirits, which influence trance-utterance or automatic script. A case bearing some resemblance to it, however, is given in _Proceedings_ S.P.R., vol. viii. p. 233, the main difference being that the repeated communications are there made in _dream_, and in _Proceedings_ S.P.R., vol. v. p. 450, [714 A], is recorded another case, where the deceased person seems to make repeated efforts to impress on survivors a wish prompted by continued affection. Less uncommon are the cases where an apparition, occurring singly and not repeated, indicates a continued knowledge of the affairs of earth. That knowledge, indeed, runs mainly, as we shall presently see, in two directions. There is often knowledge of some circumstance connected with the deceased person's own death, as the appearance of his body after dissolution, or the place of its temporary deposit or final burial. And there is often knowledge of the impending or actual death of some friend of the deceased person's. On the view here taken of the gradual passage from the one environment into the other, both these kinds of knowledge seem probable enough. I think it likely that some part of the consciousness after death may for some time be dreamily occupied with the physical scene. And similarly, when some surviving friend is gradually verging towards the same dissolution, the fact may be readily perceptible in the spiritual world. When the friend has actually died, the knowledge which his predecessor may have of his transition is knowledge appertaining to events of the next world as much as of this. But apart from this information, acquired perhaps on the borderland between two states, apparitions do sometimes imply a perception of more definitely terrene events, such as the moral crises (as marriage, grave quarrels, or impending crimes) of friends left behind on earth. In _Proceedings_ S.P.R., vol. vi. p. 25 [716 A], is a case of impressive warning, in which the phantom was seen by two persons, one of whom had already had a less evidential experience. In another case of similar type,[141] the message, while felt by the percipient to be convincing and satisfactory, was held too private to be communicated in detail. It is plain that just in the cases where the message is most ultimately veracious, the greatest difficulty is likely to be felt as to making it known to strangers.
