Do you ever have dreams that give you hope? Or dreams that make you anxious? Are they rooted in reality? Or completely off the wall?

In my dreams, I may see people I haven't spoken to in years, I occasionally even see my brother although I think I know, in the dream, that he is dead. It always seems as if I am normal and healthy, but I always know that I am not. I rarely awake disappointed because although I may mistake a dream for reality, it's never the reality that I want.
