"Her Darkened Lair"
"The Forest Whispers..."
Carmilla, by J. Sheridan Le Fanu.
"I cannot call it a nightmare, for I was quite conscious of being asleep. But I was equally conscious of being in my room, and lying in bed, precisely as I actually was. I saw, or fancied I saw, the room and its furniture just as I had seen it last, except that it was very dark, and I saw something moving round the foot of the bed, which at first I could not accurately distinguish. But I soon saw that it was a sooty-black animal that resembled a monstrous cat. It appeared to me about four or five feet long for it measured fully the length of the hearthrug as it passed over it; and it continued to-ing and fro-ing with the lithe, sinister restlessness of a beast in a cage. I could not cry out, although as you may suppose, I was terrified. Its pace was growing faster, and the room rapidly darker and darker, and at length so dark that I could no longer see anything of it but its eyes.
I felt it spring lightly on the bed. The two broad eyes approached my face, and suddenly I felt a stinging pain as if two large needles darted, an inch or two apart, deep into my breast. I waked with a scream. The room was lighted by the candle that burnt there all through the night, and I saw a female figure standing at the foot of the bed, a little at the right side. It was in a dark loose dress, and its hair was down and covered its shoulders. A block of stone could not have been more still. There was not the slightest stir of respiration. As I stared at it, the figure appeared to have changed its place, and was now nearer the door; then, close to it, the door opened, and it passed out."
And a song to go along with it:
