Final answer:
Burrage establishes an uneasy feeling by highlighting decay, loss, and parallels between characters and their settings, effectively immersing the reader in a world filled with foreboding and fear through vivid descriptions and emotional responses.
Step-by-step explanation:
Burrage creates an uneasy feeling in the reader by depicting scenes and characters that exude a sense of decay and loss, which mirrors the inner turmoil of the characters. The juxtaposition of Roderick Usher's former strength with his current frailty, and the house's once vibrant state with its present gloom, elicits a mood of melancholy and disquiet. The narrator's own desire to see these observations as a dream indicates a longing to escape the oppressive atmosphere. Burrage's use of vivid descriptions and parallels between characters and settings, like the wild hair of Usher resembling the overgrown moss on the house, effectively immerses the reader in the unnerving world he has created.
Echoing this sentiment, the reader encounters intense darkness, hollow sounds, and haunting silences, all described in detail, heightening the foreboding and fear. The meticulous attention to atmospheric detail and the focus on characters' emotional responses to their eerie surroundings engage the reader's senses and emotions, anchoring the uneasy feeling that permeates the narrative.
