Hello, could you please show me the excerpt so I can give you a sufficient answer?
In Edgar Allan Poe's "The Raven", the speaker becomes angry with the raven because <em>it constantly utters the word 'nevermore'</em>. At first, the narrator thinks that nevermore is a word that the raven has learned from its former master. But when the narrator asks if he will see Lenore in heaven, if the raven will leave the bust of Palas, and if his soul will leave the raven's shadow, the raven responds to every question with 'nevermore'.
It states how he asks the question of was it a dream. his point of view affects your experience as a reader is that you learn how and why that was a or not a dream.
