Answer:
The theme of the poem is:
B. Words of love are worthy of speaking anytime.
Explanation:
"In every deed shall mingle, love," says the speaker at the end of the poem. Love can intrude, can disrupt anything at anytime, because it is love. Even in one's sleep, even if one's dreaming, love is worth listening to. The speaker may be tired, sleepy, but he craves his muse's love, and so his words shall carry his feelings: "The lover's voice tonight shall flow."
Answer is B to my knowledge
The title could be interpreted as a story about a man's dream and the confusion of was he dreaming or did it actually happen. Or it could be interpreted as a delusion a man had and he is having trouble figuring out the difference between reality or imagination.
