This poem could have also been categorized under nightmares, since it appears to be about an experience of suffering in dreams as preferable to suffering in the real world. However, in my opinion, at its core this poem is about what it means to live in dreams, not about the content of the dreams itself.
We dream—it is good we are dreaming—
It would hurt us—were we awake—
But since it is playing—kill us,
And we are playing—shriek—
What harm? Men die—externally—
It is a truth—of Blood—
But we—are dying in Drama—
And Drama—is never dead—
Cautious—We jar each other—
And either—open the eyes—
Lest the Phantasm—prove the Mistake—
And the livid Surprise
Cool us to Shafts of Granite—
With just an Age—and Name—
And perhaps a phrase in Egyptian—
It's prudenter—to dream—
