Edgar Allen Poe creates quite a bit of suspense in "The Raven." The setting is established as a "midnight dreary" and "bleak December" where our narrator cannot seem to rest peacefully. He begins to hear noises and voices "rapping at my chamber door." He proceeds to open the door to find no one there, yet he still hears voices that speak the name of his lost love, Lenore. Now, by this point, we realize that the narrator is very upset about Lenore noting being present for the narrator declares, "For the rare and radiant maiden whom the angels name Lenore—Nameless here for evermore." While we do not know the circumstances of this lost love being gone, the narrator is up late at night, thinking about Lenore when he begins to hear the name whispered. The curtains are moving and the narrator peers out into the darkness, wondering and fearing, attempting "to still the beating of my heart." Readers too wonder what might happen next. Is someone or something there?
Finally, a raven seemingly appears at his window. The narrator, relieved, proceeds to have quite an intense conversation with this bird, most likely due to the narrator being reclusive upon stating "other friends have flown before." He seems to dwell and more the lose of Lenore by isolating himself from the world. The narrator becomes further mystified when the raven begins to speak and say "nevermore." Immediately the narrator believes the raven is referring to his lost love and the mood of the poem shifts as the narrator's anger builds the more the raven replays "nevermore" to his inquires about being with Lenore once more. The continued repetition of 'nevermore' along with the intensity of the narrator's dialogue build upon the suspense of what is or is not real. Is the narrator have a conversation with a raven or is this all in his imagination, stemming from too much time alone? The many references to evil, hell,shadows and demons place a further chilling mood to the poem.
