Honestly, if your brain is still being bothered by those experiences, I have found it means that I have not dealt with those experiences enough. There is something "unfinished" with that experience that my brain can't figure out, so it keeps circle back through it. Especially for traumatic things or big events...

I'm just an average joe with no relevant background here, but I think the purpose of memory is to help you go through similar experiences in the future more efficiently / correctly / with good outcomes.

So I think that the brain is trying to learn from those experiences. And if it wont let go, you should help it. Sit down and write out what you are thinking. Talk out loud to yourself. or to someone else you trust. Think about that event a lot. Think about what it taught you. What you want to repeat in the future. What you don't. Write about it some more.

At least on my end, that helps. Good luck.
