There are several elements that Poe uses in this excerpt in order to create a mood of terror throughout the story. Poe employs long and careful descriptions when talking about the actions of the character. He tells us that the door was opened little by little and that the sleeping man moved slightly. Another strategy that Poe employs is that he describes the scene as one "black as pitch," making the reader wonder what hides in the darkness. Finally, Poe creates suspense by describing the tension that the protagonist feels, suggesting that a surprise might come soon.
