why the dream?

Sometimes I wonder, why should human dream? Is it as a sign (somehow)? Or it's just a simple candy of the slumber? Or, it's the way life remind the brain from some memories, prevent it to forget?

I often have a dream that I never expected before. And, most of those dreams remind me of the pain for having some hidden feelings toward people that out of my reach..

Dreams...to me is more like an annoying mysteries, ready to reveal.. and sometimes, you just don't like whatever lies behind the curtain!

*sigh*
