“Naturally I thought that I had cut myself; but a close examination revealed no cut or bruise of any sort. I lit a lamp and went back upstairs. My first glance was at the spot where I had first felt the wetness. A glance revealed the cause. Directly in the center of the bare board floor was a large pool of fresh blood. It was slowly spreading out over the floor, and sinking into the dry wood. I cleaned it up as much as possible, and then searched the room thoroughly. There was absolutely nothing that I could find that would explain the blood.

“The next morning, both my sister and my niece complained of feeling languid and fagged. My niece, a very white, frail girl, was even more colorless than usual, and her mother, noticeable for her deep intense eyes and the black rings that encircle them, seemed listless and indifferent to everything. Noting this, I scrubbed up the bloodstains before they made up the room, and said nothing of what I had seen.

“Things were normal until Monday night. Again, about the same hour, I was awakened by a smothering sensation. Once more I heard my own breathing as I gasped for air. As I got more fully awake, I found that the smothering sensation grew more intense. I sat up in bed, crouched over like one suffering with the asthma, and striving to fill my lungs with air. But this did not relieve my distress.

“Unconsciously, my eyes were fixed across the dark room. Again occurred the weaving of the shadows. Panting, stifling, and seemingly unable to arouse myself enough to get out of bed, I watched the repetition of the scene of the previous night. Once the horizontal streams of shadows were formed, my breathing became more normal, and I seemed to regain the power to move and think clearly.

“I then deliberately waited to see the finish of the affair. The banks of twisting shadows disappeared down the stairway, and the two figures repeated their previous trip. As soon as they had descended past the window, I sprang from bed and lit my lamp. My eyes went at once to the floor. The pool of fresh blood was there for the second time. I let it lay and tiptoed down stairs, and to the women’s room. Both were in a sound sleep, but I was struck at once by the haggardness of their features.

“I did not awake them. Getting a basin and water, I returned upstairs. I again scrubbed up the floor, this time with much care, as the stain had now gone deep into the aged boards. Leaving the lamp lit, I went back to bed. Finally I fell asleep. Nothing occurred during the remainder of the night.

“The morning after this second visitation,” resumed Hayden, “I again remarked the extreme pallor of my niece and the haggard, gaunt face of her mother. Still, I remained silent, determined to solve the riddle for myself.

“Last night I retired early, and I took several precautions. First, I secured an electric flashlight. Next, I powdered the stairs with flour. I also sprinkled the floor on the attic room. I now had a trap that no human being, or any mechanical figure, could tread over without leaving a trace. This done, I blew out the lamp and went to bed.

“I lay awake for a matter of two or three hours. I was determined to stay awake until the shadows commenced to form, or until I began to feel the smothering sensation. In this way, I would have a grasp on it from beginning to end. But in spite of my resolution, I fell asleep.

“I was again awakened by an uncanny feeling. Firm hands, or, rather, some peculiar force, seemed to hold my arms down on the bed. I sought to draw up my legs in order to slip out of bed, but found them held by an unyielding power. Finally, I discovered that I was unable to move any part of my body. I was certainly awake, yet I was as helpless as a person in a nightmare, who fancies that his body is totally paralyzed.
