What are the questions ? I just did that short story
The Bible verse that Faust quotes is meant to teach Christians that all people are sinners and that sin leads to death. HOWEVER- Christians believe that God forgives sinners who repent. The versus are meant to cause people to repent, not despair- so it shows he doesn't understand Christianity
D. Faustus does not truly understand Christianity
when a person does not get enough sleep there mind begins to "trick" them into thinking thing are happening when they are not or in other words hallucinations. this can happen when the person does not get enough food as well, but to the events of the story the most likely would be the lack of getting enough sleep, because in you dreams you are only thinking without a filter.
so the answers are hallucinations and inability to sleep
The story is set largely in catacombs underneath Montresor's home in Italy. The setting contributes significantly to the horror of the story. It is dark, cold, and damp in the catacombs. Because catacombs are burial vaults, Montresor and Fortunato pass by piles of bones, the remains of dead bodies.
The setting impacts the plot by the use of morbid imagery and tone as well as the demeanor of the characters. The mood of the story is one of impending doom and suspense. The setting impacts the mood with the dark imagery and morbid symbolism used throughout.
