DREAMING?

On this day that began heavy and grey and turned into an afternoon filled with the pure and beautiful glories of a seaside day, I came across these words:
I dreamed I was a butterfly flitting around in the sky. Then I awoke. Now wonder: Am I a woman who dreamt of being a butterfly, or am I a butterfly dreaming that I am a woman? (Zhuanzi)
The words seemed too perfect as it was most definitely a day for dreaming.  Hmmmm--woman or butterfly?  Must there be a decision?
