Zhuangzi and the Girl

As the well known Chinese story goes.

Once Zhuangzi dreamt he was a butterfly, a butterfly flitting and fluttering around, happy with himself and doing as he pleased. He didn't know he was Zhuangzi. Suddenly he woke up and there he was, solid and unmistakable Zhuangzi. But he didn't know if he was Zhuangzi who had dreamt he was a butterfly, or a butterfly dreaming he was Zhuangzi.

And now. The world offers unlimited number of things but the amount of things we perceive and understand is limited.

And what does this have to do with the pictures of the running train and the reading girl in it.

Think about it.
