existing in the dream of a butterfly ? – 莊周夢蝶

“Chuang Tzu dreamed of a butterfly”  -  from “Equality of Things”  (~ 300 B.C.)

Chuang Tzu once dreamed that he was a butterfly.  The dream was so real.  
After he woke up,  he started to wonder  -
“Is he a man who dreamed that he was a butterfly ?”    or
“Is he a butterfly, now dreaming that he is a man ?”
“Is his whole life existing in the dream of a butterfly ?”
He thought human beings cannot distinguish between real and unreal.

This reminds me of the script of my favorite movie, The Matrix  (1999 A.D.) :
“If real is what you can feel, smell, taste and see, then ‘real’ is simply electrical signals interpreted by your brain.”
