Post your crazy dreams here. I will interpret them.

was this a day dream?
My professional opinion would say that the part about the guitar is an inner struggle with your own sexuality. The body of the guitar is female shaped while the neck could be similiar to a male phallic object. These two work together in harmony...you seek such a harmonious amalgamation in your own life.
Were the singing this:
Puerto Rico...
You lovely island ...
Island of tropical breezes
Always the pineapples growing,
Always the coffee blossoms blowing...

Puerto Rico:
You ugly island...
Island of tropic diseases.
Always the hurricanes blowing,
Always the population growing...
And the money owing,
And the babies crying,
And the bullets flying.
I like the island Manhattan -
Smoke on your pipe and put that in!

I like to be in America!
Okay by me in America!
Everything free in America
For a small fee in America

The aspect of Puerto Ricans in your dream is in reference to control. Just as the US is controlling PR you fear being controlled by a large bullying nation. Or it is a clear drug reference...
