I Felt a Funeral, in my Brain

In Emily Dickinson's poem, "I Felt a Funeral, in my Brain," the speaker has become crazy. She repeats "treading" and "beating" to expound her lunacy (Dickinson, 776). When a person has a terrible headache, every sound seems to be intensified. The sounds pound inside of her head. She focuses on the sounds, which increases her feeling of craziness. Also, she states that the "Plank of Reason" broke. As it breaks, she finds herself randomly in the world, but then, she plunges back into her insanity. Eventually, she has lost all reasons for her actions. She finishes life without a true grasp on reality. With the last line, "Finished knowing-then- (776)", she has gone crazy.
