Wild Nights - Wild Nights! Emily Dickinson

Wild Night - Wild Night!
Were I wish thee
Wild Nights should be
Our luxury!

Futile - the Winds -
To a Heart in port -
Done with the Compass -
Done with the Chart!

Rowing in Eden -
Ah, the sea!

Might I but moor - Tonight -
In thee!

It is said to be a love song talkng about Emily's viewpoint on love affair.
I am wondering whatthe grammatical mood of the poem is and how it works in the poem.Does the song create some kind of contrast?
