But while he thus lay, there came to him in some secret cell of the mind a dreadful vision, which he could only dimly remember afterwards with a fitful horror. He thought that he was walking in the cloister of some great house or college, a cool place, with a pleasant garden in the court. He paced up and down, and each time that he did so, he paused a little before a great door at the end, a huge blind portal, with much carving about it, which he somehow knew he was forbidden to enter. Nevertheless, each time that he came to it, he felt a strong wish, that constantly increased, to set foot therein. Now in the dream there fell on him a certain heaviness, and the shadow of a cloud fell over the court, and struck the sunshine out of it. And at last he made up his mind that he would enter. He pushed the door open with much difficulty, and found himself in a long blank passage, very damp and chilly, but with a glimmering light; he walked a few paces down it. The flags underfoot were slimy, and the walls streamed with damp. He then thought that he would return; but the great door was closed behind him, and he could not open it. This made him very fearful; and while he considered what he should do, he saw a tall and angry-looking man approaching very swiftly down the passage. As he turned to face him, the other came straight to him, and asked him very sternly what he did there; to which Anthony replied that he had found the door open. To which the other replied that it was fast now, and that he must go forward. He seized Anthony as he spoke by the arm, and urged him down the passage. Anthony would fain have resisted, but he felt like a child in the grip of a giant, and went forward in great terror and perplexity. Presently they came to a door in the side of the wall, and as they passed it, there stepped out an ugly shadowy thing, the nature of which he could not clearly discern, and marched softly behind them. Soon they came to a turn in the passage, and in a moment the way stopped on the brink of a dark well, that seemed to go down a long way into the earth, and out of which came a cold fetid air, with a hollow sound like a complaining voice. Anthony drew back as far as he could from the pit, and set his back to the wall, his companion letting go of him. But he could not go backward, for the thing behind him was in the passage, and barred the way, creeping slowly nearer. Then Anthony was in a great agony of mind, and waited for the end.
