Explanation:

Robert Frost's "Stopping by Woods on a Snowy Evening" is a metaphorical poem about life in general. The poem is a reflection on nature as well as human life.

Told from the perspective of a traveler going through a forest, the narrator watched the snowfall on the trees. Taking in on the lovely scene before him, the speaker then recounts the beauty of nature. He then expresses the way ahead, admitting that even though he likes the scene before him, he must move on.

The woods are lovely, dark and deep,

But I have promises to keep,

And miles to go before I sleep,

And miles to go before I sleep.

The word "sleep" here symbolizes the darkness of the night that's approaching, or metaphorically, death.
