"We'll meet again, right?," a little boy holds my hands before he leave me alone in the playground.

I never know everything about him from that day, and lately I dream about him, meeting him in the same playground but he's not a little boy anymore. I can't see his face clearly, but I hear what he said to me, "How are you?," and the dream end. Is it a sign that I'll meet him someday? or is it just a normal dream?
