> 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 would like to second this. Human beings are really good in putting stuff away in their head and convincing themselves things are okay when they aren't.
