I was fast asleep . Suddenly I heard a knock at the door . I thought it can't have been my parents they've already fallen asleep . I walked quietly to my brother Justin's door and knocked on it. He opened it and asked me gently what was wrong. I told him that I had heard a noise at the door and I felt scared . Justin said I could stay in his room as long as i wanted. In the morning we'd found out that there was a cat at the door and it had ran away from its owner to find food . We returned the cat to its owner and she thanked us for bringing her cat back safe. Hope this helps
The speaker is unsettled by the raven's repetition of “Nevermore” because he believes the raven learned it from a depressed former master and intends to make him his new owner.
