What is the main conflict in I felt a Funeral, in my Brain by Emily Dickinson?

Like many of Dickinson's other poems, "I felt a Funeral, in my Brain" explores the workings of the human mind under stress and attempts to replicate the stages of a mental breakdown through the overall metaphor of a funeral. The common rituals of a funeral are used byDickinson to mark the stages of the speaker's mental collapse until she faces a destruction that no words can articulate.
