Read the excerpt from poe's "the fall of the house of usher." i reined my horse to the precipitous brink of a black and lurid tarn that lay in the unruffled lustre by the dwelling, and gazed down -- but with a shudder even more thrilling than before -- upon the remodelled and inverted images of the gray sedge. how does this excerpt provide information about the narrator of the story?

This excerpt from the opening paragraph of "The Fall of the House of Usher" provides information about the narrator of the story by describing what he experienced, suggesting that he made a decision that somehow attempted to modified a previous, seemingly unpleasant or uncomfortable, experience (since it had giving him a "thrilling shudder"): while on horseback, he led his horse to the steep edge of a macabre tarn that lay by the dwelling that he was visiting (the House of Usher) and looked down upon the gray sedge, but this time with different eyes - "the remodelled and inverted images." It seems as if the narrator was trying to look again at what he had looked at before, with the aim of modifying the shuddering and sorrowful impression of his initial observation.
