What are the hyperboles in Emily Dickinson's "My life had stood—a Loaded Gun—"?

Emily Dickinson's "My life had stood--a Loaded Gun" contains one main  hyperbole. A hyperbole is an obvious exaggeration made by an author (in literature) to emphasize something. In some cases, hyperboles can be metaphors (which provide a comparison between dissimilar things). In this case, an author may provide a metaphor to exaggerate the existence or being of something. 

In the case of the poem, Dickinson uses metaphors to illustrate the exaggerations. The speaker's life is ready to explode (not literally, but figuratively). This image is created by the metaphor of the speaker's life to a gun. The poem, one long extended metaphor, stands to exaggerate on how the speaker's life is like a gun. 

The speaker has the ability to be carried away, hunt, roam, and take the life of another. Although not defined as a specific hyperbole, the comparison of one's life to a gun can be identified as an exaggeration in its own right. 

What are the themes and ideas in Emily Dickinson's "My life had stood—a Loaded Gun—"?

One technique is allegory. The poem compares something in her life to a loaded gun:

My Life had stood - a Loaded Gun -
In Corners - till a Day
The Owner passed - identified -
And carried Me away

What really IS the loaded gun? It represents anger, anger so strong, it has the power to kill. Anger which most of the time she hides, "in a corner" but sometimes, it "carries her away":

Though I than He - may longer live
He longer must - than I -
For I have but the power to kill,
Without--the power to die--

There is also personification. The speaker and the "gun" go out hunting together (the gun is personified):

And now We roam in Sovereign Woods -
And now We hunt the Doe -
And every time I speak for Him -
The Mountains straight reply -

There is other personification in the poem as well (the mountains straight reply).

Some critics believe that this poem is autobiographical, as much of Dickinson's work was, and expresses anger at her repressed role as a woman in the society in which she lived.

What do you think? Her work is ambiguous at times, so you could have your own interpretation. Read about Emily here on enotes.
