Romance, Obsession, and Imagination.
This book expresses the poet's romantic thoughts and admiration of a person they have an unquenchable crush on. The poet is not a very direct person and they use metaphors, riddles, and many other language tricks to embody what they intend to say to their crush.
In the poem, "The Dream", the poet talks about watching the earth flood as they sit at the brink of the cumulonimbus, but as the poet continues through the poem it unravels to the reader that the poet is not talking about a real flood or cumulonimbus, instead the poet uses all those meteorological terms as a way to censor their sexual imagination.
The poet expresses their thoughts in this book because they never had the chance to tell their crush how they feel. Their only regret is not having the courage to express their feelings to the one that they admired unconditionally.
