I don't have a dream...

I need a dream. Not the kind like I had this summer. I had a recurring dream- nightmare, really- where I would be standing in front of a room full of students, screaming at them to be quiet. That dream has become a reality. This is not the kind of dream I am talking about.
I was once asked to think of one word that would best describe me. My answer was 'dreamer'. In fact, I thought if I were to ever get a tatoo, it just might be that word. My outlook on life has always been on the idealistic side. But I feel this has not been the case lately. And so, I need a dream. What will I pursue? Who will I become? Where will I go next?
