With this again may be compared a case in _Phantasms of the Living_ (vol. ii. p. 368), where a dreamer seems to himself to be present in the Thames Tunnel during a fatal accident, which did in fact occur during that night. Here again the drowned workman--who was quite unknown to the distant dreamer--can hardly be called an _agent_; yet it may have been the excitement surrounding his death which attracted the dreamer's spirit to that scene, as a conflagration might attract a waking night-wanderer. There are, on the other hand, a good many cases where a scene thus discerned in a flash is one of special interest to the percipient, although no one in the scene may have actually wished to transfer it to him. A case again of a somewhat different type is the sudden waking vision of Mr. Gottschalk,[118] who sees in a circle of light the chalked hands and ruffled wrists of Mr. Courtenay Thorpe--a well-known actor--who was opening a letter of Mr. Gottschalk's in that costume at the time. Trivial in itself, this incident illustrates an interesting class of cases, where a picture very much like a crystal-vision suddenly appears on a wall or even in the air with no apparent background. I know one or two persons who have had in their lives one single round or oval hallucinatory picture of this kind, of which no interpretation was apparent,--a curious indication of some subliminal predisposition towards this somewhat elaborate form of message. Somewhat like Mr. Gottschalk's projection of his picture upon a background of dark air is the experience of Mrs. Taunton.[119] In this case the phantasm was perfectly external; yet it certainly did not hold to the real objects around the same relation as a figure of flesh and blood would have held; it was in a peculiar way transparent. Gurney regards this transparency as indicating _imperfect externalisation_ of the hallucinatory image. My own phrase, "imperfect _co-ordination_ of inner with outward vision," comes to much the same thing, and seems specially applicable to Mrs. Taunton's words: "The appearance was not transparent or filmy, but perfectly solid-looking; _and yet I could somehow see the orchestra, not through, but behind it_." There are a few cases where the percipient seems to see a hallucinatory figure _behind_ him, out of the range of optical vision.[120] There is of course no reason why this should not be so,--even if a part of space external to the percipient's brain should be actually affected. Mr. Searle's case also is very interesting.[121] Here Mrs. Searle faints when visiting a house a few miles from Mr. Searle's chambers in the Temple. At or about the same time, he sees as though in a looking-glass, upon a window opposite him, his wife's head and face, white and bloodless. Gurney suggests that this was a transference from Mrs. Searle's mind simply of "the _idea_ of fainting," which then worked itself out into perception in an appropriate fashion.
