1My reabsorption into normal life was a painful and difficult process. The loss of over five years creates more complications than can be imagined, and in my case there were countless matters to be adjusted. What I heard of my actions since 1908 astonished and disturbed me, but I tried to view the matter as philosophically as I could. At last regaining custody of my second son Wingate, I settled down with him in the Crane Street house and endeavoured to resume teaching—my old professorship having been kindly offered me by the college.

2I began work with the February, 1914, term, and kept at it just a year. By that time I realised how badly my experience had shaken me. Though perfectly sane—I hoped—and with no flaw in my original personality, I had not the nervous energy of the old days. Vague dreams and queer ideas continually haunted me, and when the outbreak of the world war turned my mind to history I found myself thinking of periods and events in the oddest possible fashion. My conception of time—my ability to distinguish between consecutiveness and simultaneousness—seemed subtly disordered; so that I formed chimerical notions about living in one age and casting one’s mind all over eternity for knowledge of past and future ages.

3The war gave me strange impressions of remembering some of its far-off consequences—as if I knew how it was coming out and could look back upon it in the light of future information. All such quasi-memories were attended with much pain, and with a feeling that some artificial psychological barrier was set against them. When I diffidently hinted to others about my impressions I met with varied responses. Some persons looked uncomfortably at me, but men in the mathematics department spoke of new developments in those theories of relativity—then discussed only in learned circles—which were later to become so famous. Dr. Albert Einstein, they said, was rapidly reducing time to the status of a mere dimension.

4But the dreams and disturbed feelings gained on me, so that I had to drop my regular work in 1915. Certain of the impressions were taking an annoying shape—giving me the persistent notion that my amnesia had formed some unholy sort of exchange; that the secondary personality had indeed been an intruding force from unknown regions, and that my own personality had suffered displacement. Thus I was driven to vague and frightful speculations concerning the whereabouts of my true self during the years that another had held my body. The curious knowledge and strange conduct of my body’s late tenant troubled me more and more as I learned further details from persons, papers, and magazines. Queernesses that had baffled others seemed to harmonise terribly with some background of black knowledge which festered in the chasms of my subconscious. I began to search feverishly for every scrap of information bearing on the studies and travels of that other one during the dark years.

5Not all of my troubles were as semi-abstract as this. There were the dreams—and these seemed to grow in vividness and concreteness. Knowing how most would regard them, I seldom mentioned them to anyone but my son or certain trusted psychologists, but eventually I commenced a scientific study of other cases in order to see how typical or non-typical such visions might be among amnesia victims. My results, aided by psychologists, historians, anthropologists, and mental specialists of wide experience, and by a study that included all records of split personalities from the days of daemoniac-possession legends to the medically realistic present, at first bothered me more than they consoled me.

6I soon found that my dreams had indeed no counterpart in the overwhelming bulk of true amnesia cases. There remained, however, a tiny residue of accounts which for years baffled and shocked me with their parallelism to my own experience. Some of them were bits of ancient folklore; others were case-histories in the annals of medicine; one or two were anecdotes obscurely buried in standard histories. It thus appeared that, while my special kind of affliction was prodigiously rare, instances of it had occurred at long intervals ever since the beginning of man’s annals. Some centuries might contain one, two, or three cases; others none—or at least none whose record survived.

7The essence was always the same—a person of keen thoughtfulness seized with a strange secondary life and leading for a greater or lesser period an utterly alien existence typified at first by vocal and bodily awkwardness, and later by a wholesale acquisition of scientific, historic, artistic, and anthropological knowledge; an acquisition carried on with feverish zest and with a wholly abnormal absorptive power. Then a sudden return of the rightful consciousness, intermittently plagued ever after with vague unplaceable dreams suggesting fragments of some hideous memory elaborately blotted out. And the close resemblance of those nightmares to my own—even in some of the smallest particulars—left no doubt in my mind of their significantly typical nature. One or two of the cases had an added ring of faint, blasphemous familiarity, as if I had heard of them before through some cosmic channel too morbid and frightful to contemplate. In three instances there was specific mention of such an unknown machine as had been in my house before the second change.

8Another thing that cloudily worried me during my investigation was the somewhat greater frequency of cases where a brief, elusive glimpse of the typical nightmares was afforded to persons not visited with well-defined amnesia. These persons were largely of mediocre mind or less—some so primitive that they could scarcely be thought of as vehicles for abnormal scholarship and preternatural mental acquisitions. For a second they would be fired with alien force—then a backward lapse and a thin, swift-fading memory of un-human horrors.

9There had been at least three such cases during the past half century—one only fifteen years before. Had something been groping blindly through time from some unsuspected abyss in Nature? Were these faint cases monstrous, sinister experiments of a kind and authorship utterly beyond sane belief? Such were a few of the formless speculations of my weaker hours—fancies abetted by myths which my studies uncovered. For I could not doubt but that certain persistent legends of immemorial antiquity, apparently unknown to the victims and physicians connected with recent amnesia cases, formed a striking and awesome elaboration of memory lapses such as mine.

10Of the nature of the dreams and impressions which were growing so clamorous I still almost fear to speak. They seemed to savour of madness, and at times I believed I was indeed going mad. Was there a special type of delusion afflicting those who had suffered lapses of memory? Conceivably, the efforts of the subconscious mind to fill up a perplexing blank with pseudo-memories might give rise to strange imaginative vagaries. This, indeed (though an alternative folklore theory finally seemed to me more plausible), was the belief of many of the alienists who helped me in my search for parallel cases, and who shared my puzzlement at the exact resemblances sometimes discovered. They did not call the condition true insanity, but classed it rather among neurotic disorders. My course in trying to track it down and analyse it, instead of vainly seeking to dismiss or forget it, they heartily endorsed as correct according to the best psychological principles. I especially valued the advice of such physicians as had studied me during my possession by the other personality.

11My first disturbances were not visual at all, but concerned the more abstract matters which I have mentioned. There was, too, a feeling of profound and inexplicable horror concerning myself. I developed a queer fear of seeing my own form, as if my eyes would find it something utterly alien and inconceivably abhorrent. When I did glance down and behold the familiar human shape in quiet grey or blue clothing I always felt a curious relief, though in order to gain this relief I had to conquer an infinite dread. I shunned mirrors as much as possible, and was always shaved at the barber’s.

12It was a long time before I correlated any of these disjointed feelings with the fleeting visual impressions which began to develop. The first such correlation had to do with the odd sensation of an external, artificial restraint on my memory. I felt that the snatches of sight I experienced had a profound and terrible meaning, and a frightful connexion with myself, but that some purposeful influence held me from grasping that meaning and that connexion. Then came that queerness about the element of time, and with it desperate efforts to place the fragmentary dream-glimpses in the chronological and spatial pattern.

13The glimpses themselves were at first merely strange rather than horrible. I would seem to be in an enormous vaulted chamber whose lofty stone groinings were well-nigh lost in the shadows overhead. In whatever time or place the scene might be, the principle of the arch was known as fully and used as extensively as by the Romans. There were colossal round windows and high arched doors, and pedestals or tables each as tall as the height of an ordinary room. Vast shelves of dark wood lined the walls, holding what seemed to be volumes of immense size with strange hieroglyphs on their backs. The exposed stonework held curious carvings, always in curvilinear mathematical designs, and there were chiselled inscriptions in the same characters that the huge books bore. The dark granite masonry was of a monstrous megalithic type, with lines of convex-topped blocks fitting the concave-bottomed courses which rested upon them. There were no chairs, but the tops of the vast pedestals were littered with books, papers, and what seemed to be writing materials—oddly figured jars of a purplish metal, and rods with stained tips. Tall as the pedestals were, I seemed at times able to view them from above. On some of them were great globes of luminous crystal serving as lamps, and inexplicable machines formed of vitreous tubes and metal rods. The windows were glazed, and latticed with stout-looking bars. Though I dared not approach and peer out them, I could see from where I was the waving tops of singular fern-like growths. The floor was of massive octagonal flagstones, while rugs and hangings were entirely lacking.

14Later I had visions of sweeping through Cyclopean corridors of stone, and up and down gigantic inclined planes of the same monstrous masonry. There were no stairs anywhere, nor was any passageway less than thirty feet wide. Some of the structures through which I floated must have towered into the sky for thousands of feet. There were multiple levels of black vaults below, and never-opened trap-doors, sealed down with metal bands and holding dim suggestions of some special peril. I seemed to be a prisoner, and horror hung broodingly over everything I saw. I felt that the mocking curvilinear hieroglyphs on the walls would blast my soul with their message were I not guarded by a merciful ignorance.

15Still later my dreams included vistas from the great round windows, and from the titanic flat roof, with its curious gardens, wide barren area, and high, scalloped parapet of stone, to which the topmost of the inclined planes led. There were almost endless leagues of giant buildings, each in its garden, and ranged along paved roads fully two hundred feet wide. They differed greatly in aspect, but few were less than five hundred feet square or a thousand feet high. Many seemed so limitless that they must have had a frontage of several thousand feet, while some shot up to mountainous altitudes in the grey, steamy heavens. They seemed to be mainly of stone or concrete, and most of them embodied the oddly curvilinear type of masonry noticeable in the building that held me. Roofs were flat and garden-covered, and tended to have scalloped parapets. Sometimes there were terraces and higher levels, and wide cleared spaces amidst the gardens. The great roads held hints of motion, but in the earlier visions I could not resolve this impression into details.

16In certain places I beheld enormous dark cylindrical towers which climbed far above any of the other structures. These appeared to be of a totally unique nature, and shewed signs of prodigious age and dilapidation. They were built of a bizarre type of square-cut basalt masonry, and tapered slightly toward their rounded tops. Nowhere in any of them could the least traces of windows or other apertures save huge doors be found. I noticed also some lower buildings—all crumbling with the weathering of aeons—which resembled these dark cylindrical towers in basic architecture. Around all these aberrant piles of square-cut masonry there hovered an inexplicable aura of menace and concentrated fear, like that bred by the sealed trap-doors.

17The omnipresent gardens were almost terrifying in their strangeness, with bizarre and unfamiliar forms of vegetation nodding over broad paths lined with curiously carven monoliths. Abnormally vast fern-like growths predominated; some green, and some of a ghastly, fungoid pallor. Among them rose great spectral things resembling calamites, whose bamboo-like trunks towered to fabulous heights. Then there were tufted forms like fabulous cycads, and grotesque dark-green shrubs and trees of coniferous aspect. Flowers were small, colourless, and unrecognisable, blooming in geometrical beds and at large among the greenery. In a few of the terrace and roof-top gardens were larger and more vivid blossoms of almost offensive contours and seeming to suggest artificial breeding. Fungi of inconceivable size, outlines, and colours speckled the scene in patterns bespeaking some unknown but well-established horticultural tradition. In the larger gardens on the ground there seemed to be some attempt to preserve the irregularities of Nature, but on the roofs there was more selectiveness, and more evidences of the topiary art.

18The skies were almost always moist and cloudy, and sometimes I would seem to witness tremendous rains. Once in a while, though, there would be glimpses of the sun—which looked abnormally large—and of the moon, whose markings held a touch of difference from the normal that I could never quite fathom. When—very rarely—the night sky was clear to any extent, I beheld constellations which were nearly beyond recognition. Known outlines were sometimes approximated, but seldom duplicated; and from the position of the few groups I could recognise, I felt I must be in the earth’s southern hemisphere, near the Tropic of Capricorn. The far horizon was always steamy and indistinct, but I could see that great jungles of unknown tree-ferns, calamites, lepidodendra, and sigillaria lay outside the city, their fantastic frondage waving mockingly in the shifting vapours. Now and then there would be suggestions of motion in the sky, but these my early visions never resolved.

19By the autumn of 1914 I began to have infrequent dreams of strange floatings over the city and through the regions around it. I saw interminable roads through forests of fearsome growths with mottled, fluted, and banded trunks, and past other cities as strange as the one which persistently haunted me. I saw monstrous constructions of black or iridescent stone in glades and clearings where perpetual twilight reigned, and traversed long causeways over swamps so dark that I could tell but little of their moist, towering vegetation. Once I saw an area of countless miles strown with age-blasted basaltic ruins whose architecture had been like that of the few windowless, round-topped towers in the haunting city. And once I saw the sea—a boundless steamy expanse beyond the colossal stone piers of an enormous town of domes and arches. Great shapeless suggestions of shadow moved over it, and here and there its surface was vexed with anomalous spoutings.
