What are connotations used in this poem?

That night the moon drifted over the pond,

turning the water to milk, and under

the boughs of the trees, the blue trees,

a young woman walked, and for an instant

the future came to her:

rain falling on her husband's grave, rain falling

on the lawns of her children, her own mouth

filling with cold air, strangers moving into her house,

a man in her room writing a poem, the moon drifting into it,

a woman strolling under its trees, thinking of death,

thinking of him thinking of her, and the wind

risingand taking the moon and leaving the paper dark.

Im sorry this is not one of queen elizaeths poems, its a mark strand one
