We went to the theatre that evening, and afterwards to the Café Greco, where we talked art in half a dozen languages until midnight, and then came home. Our entrance to the house and the studio was much the same as on the previous night, and we went to bed without a word. My mind naturally reverted to the experience of the night before, and I lay there for a long time with my eyes open, making a strong effort of the imagination to account for the vision by the dim shapes of the furniture, the lace curtains, and the suggestive and shadowy perspective. But, although the interior was weird enough, by reason of the dingy hangings and the diffused light, I was unable to trace the origin of the illusion to any object within the range of my vision, or to account for the strange illumination which had startled me. I went to sleep thinking of other things, and with my nerves comparatively quiet. Sometime in the early morning, about three o’clock, as near as I could judge, I slowly awoke, and saw the lace curtains illuminated as before. I found myself in an expectant frame of mind, neither calm nor excited, but rather in that condition of philosophical quiet which best prepared me for an investigation of the phenomenon which I confidently expected to witness. Perhaps this is assuming too eagerly the position of a philosopher, but I am certain no element of fear disturbed my reason, that I was neither startled nor surprised at awakening as I did, and that my mind was active and undoubtedly prepared for the investigation of the mystery. I was therefore not at all shocked to observe the same shape come first into the angle of my eye, and then into the full range of my vision, next appear as a silhouette against the curtains, and finally lose itself in the darkness of the doorway. During the progress of the shape across the room I noticed the size and general aspect of it with keen attention to detail, and with satisfactory calmness of observation. It was only after the figure had passed out of sight, and the light on the window curtains grew dim again, much as an electric light loses its brilliancy with the diminution of the strength of the current, that it occurred to me to consider the fact that during the period of the hallucination I had been utterly motionless. There was not the slightest doubt of my being awake. My friend in the adjoining bed was breathing regularly, the ticking of my watch was plainly audible, and I could feel my heart beating with unusual rapidity and vigor.
