The Illustrated Complete Works of H.P. Lovecraft

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.
    But 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.
    Not 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.
    I 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.
    The 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.
    Another 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
