or logic could shake. Curiously enough, as the original incident receded into the past, this new idea thrust itself into the foreground, and I began in my own mind to court another interview. At times, sitting alone after night, I felt that I was watched by unseen eyes; these eyes haunted me in my solitude, and I was morally sure of the presence of another than myself in the room. The sensation was at first unpleasant, and I tried to throw it off; with partial success. But only for a little while could I banish the intrusive idea, and as the thought took form, and the invisible presence became more actual to consciousness, I hoped that the stranger would make good his parting promise, "I will see you again."
On one thing I was resolved; I would at least be better informed on the subject of hallucinations and apparitions, and not be taken unawares as I had been. To this end I decided to confer with my friend, Professor Chickering, a quiet, thoughtful man, of varied accomplishments, and thoroughly read upon a great number of topics, especially in the literature of the marvelous.
So to the Professor I went, after due appointment, and confided to him full particulars of my adventure. He listened patiently throughout, and when I had finished, assured me in a matter-of-fact way that such hallucinations were by no means rare. His remark was provoking, for I did not expect from the patient interest he had shown while I was telling my story, that the whole matter would be dismissed thus summarily. I said with some warmth:
"But this was not a hallucination. I tried at first to persuade myself that it was illusory, but the more I have thought the experience over, the more real it becomes to me."
"Perhaps you were dreaming," suggested the Professor.
"No," I answered; "I have tried that hypothesis, and it will not do. Many things make that view untenable."
"Do not be too sure of that," he said; "you were, by your own account, in a highly nervous condition, and physically tired. It is possible, perhaps probable, that in this state, as you sat in your chair, you dozed off for a short interval, during which the illusion flashed through your mind."
