The touch of brain-fever and the dreams began early in February. For some time, apparently, the curious angles of Gilman's room had been having a strange, almost hypnotic effect on him; and as the bleak winter advanced he had found himself staring more and more intently at the corner where the down-slanting ceiling met the inward-slanting wall. About this period his inability to concentrate on his formal studies worried him considerably, his apprehensions about the mid-year examinations being very acute. But the exaggerated sense of bearing was scarcely less annoying. Life had become an insistent and almost unendurable cacophony, and there was that constant, terrifying impression of other sounds — perhaps from regions beyond life — trembling on the very brink of audibility. So far as concrete noises went, the rats in the ancient partitions were the worst. Sometimes their scratching seemed not only furtive but deliberate. When it came from beyond the slanting north wall it was mixed with a sort of dry rattling; and when it came from the century-closed loft above the slanting ceiling Gilman always braced himself as if expecting some horror which only bided its time before descending to engulf him utterly.

The dreams were wholly beyond the pale of sanity, and Gilman fell that they must be a result, jointly, of his studies in mathematics and in folklore. He had been thinking too much about the vague regions which his formulae told him must lie beyond the three dimensions we know, and about the possibility that old Keziah Mason — guided by some influence past all conjecture — had actually found the gate to those regions. The yellowed country records containing her testimony and that of her accusers were so damnably suggestive of things beyond human experience — and the descriptions of the darting little furry object which served as her familiar were so painfully realistic despite their incredible details.

That object — no larger than a good-sized rat and quaintly called by the townspeople "Brown Jenkins — seemed to have been the fruit of a remarkable case of sympathetic herd-delusion, for in 1692 no less than eleven persons had testified to glimpsing it. There were recent rumours, too, with a baffling and disconcerting amount of agreement. Witnesses said it had long hair and the shape of a rat, but that its sharp-toothed, bearded face was evilly human while its paws were like tiny human hands. It took messages betwixt old Keziah and the devil, and was nursed on the witch's blood, which it sucked like a vampire. Its voice was a kind of loathsome titter, and it could speak all languages. Of all the bizarre monstrosities in Gilman's dreams, nothing filled him with greater panic and nausea than this blasphemous and diminutive hybrid, whose image flitted across his vision in a form a thousandfold more hateful than anything his waking mind had deduced from the ancient records and the modern whispers.

Gilman's dreams consisted largely in plunges through limitless abysses of inexplicably coloured twilight and baffingly disordered sound; abysses whose material and gravitational properties, and whose relation to his own entity, he could not even begin to explain. He did not walk or climb, fly or swim, crawl or wriggle; yet always experienced a mode of motion partly voluntary and partly involuntary. Of his own condition he could not well judge, for sight of his arms, legs, and torso seemed always cut off by some odd disarrangement of perspective; but he felt that his physical organization and faculties were somehow marvellously transmuted and obliquely projected — though not without a certain grotesque relationship to his normal proportions and properties.

The abysses were by no means vacant, being crowded with indescribably angled masses of alien-hued substance, some of which appeared to be organic while others seemed inorganic. A few of the organic objects tended to awake vague memories in the back of his mind, though he could form no conscious idea of what they mockingly resembled or suggested. In the later dreams he began to distinguish separate categories into which the organic objects appeared to be divided, and which seemed to involve in each case a radically different species of conduct-pattern and basic motivation. Of these categories one seemed to him to include objects slightly less illogical and irrelevant in their motions than the members of the other categories.

All the objects — organic and inorganic alike — were totally beyond description or even comprehension. Gilman sometimes compared the inorganic matter to prisms, labyrinths, clusters of cubes and planes, and Cyclopean buildings; and the organic things struck him variously as groups of bubbles, octopi, centipedes, living Hindoo idols, and intricate arabesques roused into a kind of ophidian animation. Everything he saw was unspeakably menacing and horrible; and whenever one of the organic entities appeared by its motions to be noticing him, he felt a stark, hideous fright which generally jolted him awake. Of how the organic entities moved, he could tell no more than of how he moved himself. In time he observed a further mystery — the tendency of certain entities to appear suddenly out of empty space, or to disappear totally with equal suddenness. The shrieking, roaring confusion of sound which permeated the abysses was past all analysis as to pitch, timbre or rhythm; but seemed to be synchronous with vague visual changes in all the indefinite objects, organic and inorganic alike. Gilman had a constant sense of dread that it might rise to some unbearable degree of intensity during one or another of its obscure, relentlessly inevitable fluctuations.

But it was not in these vortices of complete alienage that he saw Brown Jenkin. That shocking little horror was reserved for certain lighter, sharper dreams which assailed him just before he dropped into the fullest depths of sleep. He would be lying in the dark fighting to keep awake when a faint lambent glow would seem to shimmer around the centuried room, showing in a violet mist the convergence of angled planes which had seized his brain so insidiously. The horror would appear to pop out of the rat-hole in the corner and patter toward him over the sagging, wide-planked floor with evil expectancy in its tiny, bearded human face; but mercifully, this dream always melted away before the object got close enough to nuzzle him. It had hellishly long, sharp, canine teeth; Gilman tried to stop up the rat-hole every day, but each night the real tenants of the partitions would gnaw away the obstruction, whatever it might be. Once he had the landlord nail a tin over it, but the next night the rats gnawed a fresh hole, in making which they pushed or dragged out into the room a curious little fragment of bone.

Gilman did not report his fever to the doctor, for he knew he could not pass the examinations if ordered to the college infirmary when every moment was needed for cramming. As it was, he failed in Calculus D and Advanced General Psychology, though not without hope of making up lost ground before the end of the term.

It was in March when the fresh element entered his lighter preliminary dreaming, and the nightmare shape of Brown Jenkin began to be companioned by the nebulous blur which grew more and more to resemble a bent old woman. This addition disturbed him more than he could account for, but finally he decided that it was like an ancient crone whom he had twice actually encountered in the dark tangle of lanes near the abandoned wharves. On those occasions the evil, sardonic, and seemingly unmotivated stare of the beldame had set him almost shivering — especially the first time when an overgrown rat darting across the shadowed mouth of a neighbouring alley had made him think irrationally of Brown Jenkin. Now, he reflected, those nervous fears were being mirrored in his disordered dreams. That the influence of the old house was unwholesome he could not deny, but traces of his early morbid interest still held him there. He argued that the fever alone was responsible for his nightly fantasies, and that when the touch abated he would be free from the monstrous visions. Those visions, however, were of absorbing vividness and convincingness, and whenever he awaked he retained a vague sense of having undergone much more than he remembered. He was hideously sure that in unrecalled dreams he had talked with both Brown Jenkin and the old woman, and that they had been urging him to go somewhere with them and to meet a third being of greater potency.
