I shuddered at the thought of those vital processes, worn as they were by eighty-one years of continuous functioning, in conflict with unknown forces of which the youngest and strongest system might well be afraid; but in another moment reflected that dreams are only dreams, and that these uncomfortable visions could be, at most, no more than my uncle's reaction to the investigations and expectations which had lately filled our minds to the exclusion of all else.
Conversation, also, soon tended to dispel my sense of strangeness; and in time I yielded to my yawns and took my turn at slumber. My uncle seemed now very wakeful, and welcomed his period of watching even though the nightmare had aroused him far ahead of his allotted two hours.
Sleep seized me quickly, and I was at once haunted with dreams of the most disturbing kind. I felt, in my visions, a cosmic and abysmal loneness; with hostility surging from all sides upon some prison where I lay confined. I seemed bound and gagged, and taunted by the echoing yells of distant multitudes who thirsted for my blood. My uncle's face came to me with less pleasant association than in waking hours, and I recall many futile struggles and attempts to scream. It was not a pleasant sleep, and for a second I was not sorry for the echoing shriek which clove through the barriers of dream and flung me to a sharp and startled awakeness in which every actual object before my eyes stood out with more than natural clearness and reality.
I had been lying with my face away from my uncle's chair, so that in this sudden flash of awakening I saw only the door to the street, the window, and the wall and floor and ceiling toward the north of the room, all photographed with morbid vividness on my brain in a light brighter than the glow of the fungi or the rays from the street outside. It was not a strong or even a fairly strong light; certainly not nearly strong enough to read an average book by. But it cast a shadow of myself and the cot on the floor, and had a yellowish, penetrating force that hinted at things more potent than luminosity. This I perceived with unhealthy sharpness despite the fact that two of my other senses were violently assailed. For on my ears rang the reverberations of that shocking scream, while my nostrils revolted at the stench which filled the place. My mind, as alert as my senses, recognized the gravely unusual; and almost automatically I leaped up and turned about to grasp the destructive instruments which we had left trained on the moldy spot before the fireplace. As I turned, I dreaded what I was to see; for the scream had been in my uncle's voice, and I knew not against what menace I should have to defend him and myself.
