Have you ever tried to catch a dragonfly? You see a dragonfly sitting on a twig and try to catch it, then, it flew away. The weird thing is that the dragonfly comes back in a minute forgetting that he was about to be caught right there a few minutes ago.
I thought it was like Oedipus. He committed the tragic by himself (killing his birth father) and tries to find out who did the tragic without knowing that actually it was him. In other words, he is pushing himself into the tragedy. I think we can also call it ‘destiny’. You are meant to return to the place where you left something behind undone. You have to pay the price for what you’ve done in some way during your life.
