Answer:
The description of the "House of Usher" in the first paragraph gave the feeling of dread, eerie and also something unwanted, creating a mood of fear and apprehension on both the narrator and the readers.
Step-by-step explanation:
Edgar Allen Poe's short story "The Fall of the House of Usher" tells the sad yet intimidating and rather scary tale of how the narrator had went to love with his friend. His experiences in the house, the numerous eerie events that he encountered and the eventual decision to flee the house all give a sense of gothic themes in the story.
The narrator describes the house as being "melancholy, ..... a sense of insufferable gloom pervaded my spirit" with "bleak walls, vacant eye-like windows, decayed trees". He also called it "this mansion of gloom", which give an expression of something terrible, dark and decaying. The dark and dreary setting of the -place did nothing good too. It rather creates the tone of apprehension which is also filled with fear not only on the readers but also on the narrator himself.
