"I Felt a Funeral, in my Brain" by Emily Dickinson

This poem seems as though the author is trying to express a depressing image, like someone was trying to put her into a bad mood because of how different this is. It seemed like she tried to express how a person can be dead inside though is still living. Say for instance a person was to lose their job and failed in their marriage that would then force the person into a state of depression, this then proves that a person can be dead or think their life does not mean a thing and is still a living being. Near then end it sounded like she was trying to find her sanctuary, a place she can escape which, her haven or in this case what is described as "heaven."
