“I dwell in Possibility— A fairer House than Prose— More numerous of Windows— Superior—for Doors—”

The poem is a description of a house with more windows and better doors than prose can offer, which is a way of saying that a person is larger than the account they can give of themselves. It is a private poem, never published in her lifetime, and the exuberance of the punctuation is the part that keeps it from being sentimental.
