why is the narrator "forcibly impressed" with usher's performance of "the haunted palace"
The full quote regarding the narrator's reaction to Usher's poem is, "I was, perhaps, the more forcibly impressed with it, as he gave it, because, in the under or mystic current of its meaning, I fancied that I perceived, and for the first time, a full consciousness on the part of Usher, of the tottering of his lofty reason upon her throne." In other words, the narrator can't help but be impressed with the poem because it is the first time it seems that Usher is aware of the fact that he is losing his mind. In stanza V of the poem, Usher recites, "And, round about his home, the glory / That blushed and bloomed / Is but a dim-remembered story / of the old time entombed." These lines perfectly summarize the house of Usher's fall into decay and Usher's sink into despair and madness.
