Answer:
The speaker is up late at night reading and hears a knocking sound.
Step-by-step explanation:
The Raven is a narrative poem by Edgar Allan Poe. In its opening lines, the first stanza, it speaks of a character in the first person who is reading some obscure and forgotten texts and who suddenly hears a tapping on his door. The speaker thinks it should be a visitor and nothing more. Later, we learn that a raven was at his door and that this creature came to haunt him and revive the speaker´s memories of a lost love that will not let him be at peace anymore.
