Me joining homework assistant school?

Last night I had a dream of me following a elder brother to join a homework assistant school. But then when I started asking question about the school, the course and such, the seemingly-the-principal walked by and told me that I need to pay a whole year tuition, while my brother only paid tuition up to next January. I was not too happy, and at the same time I have a strange sense of awareness that after March next year I might not be even in Hong Kong. So I started to explain stuff, and gradually I woke up.

Maybe during the explanation process, I started to aware that I was in the dream, and thus the waking up.
