I read both poems and I can immediately envision being in a beach. A white-sand beach filled with tropical fruit.
In "Dream Variations", I think of an undiscovered paradise where I am the only inhabitant. When darkness comes, it totally covers the beach and only the moon and stars provide the light.
In "The Tropics in New York", I envision a vacation spot where tropical fruits and fresh juices are being served.
For me, these places represent a simple and enjoyable time where stress is a stranger.
