A dream, what does it mean?

I had a horrible dream last night. Jurgen, his sister, his parents, and I were running away from some people. We all got separated and had to take different boats (I know, this isn't making much sense, but dreams never do). Luckily, I was on the same boat as Jurgen and we could see Anna. When we got off, we were all rejoicing about our good fortune at having escaped these awful people. Then a messenger came and told us that the final boat had been lost, and all of the people on it were dead. Everyone had written notes to their loved ones before embarking and so we were able to see the notes written from Jurgen's parents. I don't remember what exactly was in the notes, but the next thing I knew I was waking up sobbing. Sobbing.
What does this mean? Is running away representative of the persecution I feel in my own life? Is being on separate boats from Jurgen's family about how I feel slightly separated from them? And what about Jurgen's parents? And the notes? Maybe it doesn't mean anything. Maybe it is just me having watched too many movies. Maybe it was just my subconscious needing an outlet, a release, just a good cry. Who knows?
It was disturbing nonetheless.
