Orphaned so young--my condolences!
I know that dream. My sister was missing for months, then found dead. To this day I dream that she is alive again. It wasn't her they buried (I suspected it all along! We weren't allowed to see the body). In the dream, I often say, "I've dreamed this so many times, and now it's real; now it's really happening." Then I wake up. It was only a dream. The subconscious can be so cruel!
