Turning now to the cases where the phantasm is not repeated, but occurs some hours after death, let us take a few narratives where the interval of time is pretty certain, and consider how far the hypothesis of _latency_ looks probable in each instance. Where there is no actual hallucination, but only a feeling of unique _malaise_ or distress following at a few hours' interval on a friend's death at a distance, as in Archdeacon Wilson's case (i. p. 280), it is very hard to picture to ourselves what has taken place. Some injurious shock communicated to the percipient's brain at the moment of the agent's death may conceivably have slowly worked itself into consciousness. The delay may have been due, so to say, to physiological rather than to psychical causes. Next take a case like that of Mrs. Wheatcroft (i. p. 420), or of Mrs. Evens (ii. p. 690), or Sister Bertha (quoted below in Appendix VII. F), where a definite hallucination of sight or sound occurs some hours after the death, but in the middle of the night. It is in a case of this sort that we can most readily suppose that a "telepathic impact" received during the day has lain dormant until other excitations were hushed, and has externalised itself as a hallucination after the first sleep, just as when we wake from a first sleep some subject of interest or anxiety, which has been thrust out of our thoughts during the day, will often well upwards into consciousness with quite a new distinctness and force. But on the other hand, in the case (for instance) of Mrs. Teale (ii. p. 693), there is a deferment of some eight hours, and then the hallucination occurs while the percipient is sitting wide awake in the middle of her family. And in one of the most remarkable dream-cases in our collection (given in Chapter IV.), Mrs. Storie's experience does not resemble the mere emergence of a latent impression. It is long and complex, and suggests some sort of clairvoyance; but if it be "telepathic clairvoyance," that is, a picture transferred from the decedent's mind, then it almost requires us to suppose that a _post-mortem_ picture was thus transferred, a view of the accident and its consequences _fuller_ than any which could have flashed through the dying man's mind during his moment of sudden and violent death from "the striking off of the top of the skull" by a railway train.
