What are you trying to tell me?

Sorry I have been away so long. I go through phases where I just can’t talk about it. Do you have reoccurring themes? Are they telling you something? I keep having these where traumatic things happen. It all seems to be around forgiving, moving on after someone hurts you. But what doesn’t make sense to me is that I think I learned that lesson long ago. Having been through a cheating spouse, divorce,etc. I forgave and went on with my life. I don’t sit around thinking of revenge or still hold any grudges. I let it go a long time ago. So why is this theme always coming back? A MDD friend suggested it is more of a premonition preparing me for something to come. Don’t want that to be right. It does seem to always relate to a movie plot, like I see something happen in a movie that is disturbing and my mind is like, “what would you do if it happened to you?” Then I spend weeks stuck in a DD forcing me to live that scenario. How do I stop this? Why can’t I have those pleasant DDs about fame, fortune, happiness?
