At the beginning of the poem, the narrator was in mourning. He was tired and nodding off, and when he first heard the knocking on his chamber door, he was hesitant to say anything. But the second time he heard the knock, "his soul grew stronger" and he went to answer it, but no one was there. He is more emboldened at this point, but then clearly confused when the raven flies in through his window. He converses with the raven (as much as one can converse with an animal that can say only one word), and as the poem goes on, the narrator becomes more upset. The raven can only say "Nevermore," and that starts to make the narrator angry. In the end, the narrator is cursing at the bird, calling it a demon, and his calm sleepiness from the beginning has become passionate anger and despair at the raven.
