Here's a breakdown of the events, or rather, the sensations, in the poem:
* The Funeral in the Brain: The poem begins with the speaker feeling a funeral in their brain, a stark and unsettling image. The funeral procession is described, complete with mourners, a hearse, and a final, solemn "tinkle." This is a symbolic representation of the speaker's sense of loss and the gradual descent into despair.
* The Descent into Darkness: The speaker describes the descent into a dark, coffin-like space where "darkness" and "silence" reign. This symbolizes the speaker's sinking into the depths of their grief, feeling isolated and cut off from the world.
* The Weight of Grief: The speaker feels the weight of their grief, represented by the "crushing" and "tumbling" of the "world." This imagery suggests the overwhelming nature of grief and the feeling of being overwhelmed by its weight.
* The Burial of Hope: The poem ends with the speaker's "soul" being "buried," signifying the complete loss of hope and the finality of their despair. The "grave" is filled with "Moaning," which could symbolize the continued presence of grief or the speaker's own cries of anguish.
The poem is not about a specific death, but rather a universal experience of grief and the internal journey it takes us on. Dickinson's use of vivid imagery and unconventional language creates a powerful and unsettling portrayal of the emotional turmoil that comes with loss.
