Chang Tzu's Butterfly

Chang Tzu is famous for saying that he once had a dream of being a butterfly that was so vivid that he couldn't tell if he was a man dreaming that he was a butterfly or a butterfly dreaming he was a man.

 As for my meaning, I always feel a bit of a failure when I have to explain it, but I realize this is a rather opaque piece.  I'm saying that I spend my days in a stupor, wishing I could sleep and when night comes I can't sleep which disorients me so I feel like Chang Tzu with his butterfly. 

 Again, that's my meaning... but I believe when a poet writes a piece he or she hands it over to the reader.  So, while that was my intent, I consider it no more or less valid than the reader's interpretation.  (I had a very gung-ho creative writing teacher)
