“Yes—as a rule.”

“There you have it. Your painter’s psychology saw the child ‘disappopping.’ That’s all.”

“And the fly?” but the fly was easily explained, since it was merely the process reversed. “Once a process has established itself in your mind, you see, it may act in either direction. When a madman says ‘I’m afraid Smith will do me an injury,’ it means, ‘I will do an injury to Smith,’” And he repeated with finality, “That’s it.”

The explanations were not very satisfactory, the illustration even tactless, but then the problem had not been stated quite fully. Neither to the oculist nor to the other had all the facts been given. The same shyness had been a restraining influence in both cases; a detail had been omitted, and this detail was that he connected the occurrences somehow with his brother whom the war had taken.

The phenomenon made one more appearance—the last—before its character, its field of action rather, altered. He was reading a book when the print became now large, now small; it blurred, grew remote and tiny, then so huge that a single word, a letter even, filled the whole page. He felt as if someone were playing optical tricks with the mechanism of his eyes, trying first one, then another focus.

More curious still, the meaning of the words themselves became uncertain; he did not understand them any more; the sentences lost their meaning, as though he read a strange language, or a language little known. The flash came then—someone was using his eyes—someone else was looking through them.

No, it was not his brother. The idea was preposterous in any case. Yet he shivered again, as when he heard the walking wind, for an uncanny conviction came over him that it was someone who did not understand eyes but was manipulating their mechanism experimentally. With the conviction came also this: that, while not his brother, it was someone connected with his brother.

Here, moreover, was an explanation of sorts, for if the supernatural existed—he had never troubled his head about it—he could accept this odd business as a manifestation, and leave it at that. He did so, and his mind was eased. This was his attitude: “The supernatural may exist. Why not? We cannot know. But we can watch.” His eyes and brain, at any rate, were proved in good condition.

He watched. No change of focus, no magnifying or diminishing, came again. For some weeks he noticed nothing unusual of any kind, except that his mind often filled now with Eastern pictures. Their sudden irruption caught his attention, but no more than that; they were sometimes blurred and sometimes vivid; he had never been in the East; he attributed them to his constant thinking of his brother, missing in Mesopotamia these six months. Photographs in magazines and newspapers explained the rest. Yet the persistence of the pictures puzzled him: tents beneath hot cloudless skies, palms, a stretch of desert, dry watercourses, camels, a mosque, a minaret—typical snatches of this kind flashed into his mind with a sense of faint familiarity often. He knew, again, the return of a fugitive memory he could not seize.... He kept a note of the dates, all of them subsequent to the day he read his brother’s fate in the official Roll of Honour: “Believed missing; now killed.” Only when the original phenomenon returned, but in its altered form, did he stop the practice. The change then affected his life too fundamentally to trouble about mere dates and pictures.

For the phenomenon, shifting its field of action, abruptly became mental, and the singular change of focus took place now in his mind. Events magnified or contracted themselves out of all relation with their intrinsic values, sense of proportion went hopelessly astray. Love, hate and fear experienced sudden intensification, or abrupt dwindling into nothing; the familiar everyday emotions, commonplace daily acts, suffered exaggerated enlargement, or reduction into insignificance, that threatened the stability of his personality. Fortunately, as stated, they were of brief duration; to examine them in detail were to touch the painful absurdities of incipient mania almost; that a lost collar stud could block his exasperated mind for hours, filling an entire day with emotion, while a deep affection of long standing could ebb towards complete collapse suddenly without apparent cause...!
