I had a few dreams like what you have expereinced. Mine were a lot earlier, and were very distressing to me, but once i woke I was ok. I still hold the images and they make me sad when i remember the dreams
Dreaming is a subconcious way of resolving issues. Its perfectly normal, and sometimes they make no sense, but its your subconcious way of dealing with issues that have arisen, to which you may or may not be aware of.
