I had a lot of really vivid memories of seemingly meaningless situations and I only realized their meaning and involvement in my OCD and other mental complications after I managed to treat all the symptoms. I even recall just one-off thoughts I had to myself which foreshadowed my ADHD diagnosis like 5 years in advance.

One of my early vivid memories is my parents being quite upset with me for pooping in the trainer potty instead of the toilet and I only realized that might be involved in why I had been OCD about going number 2, only using the bathroom where said memory occured in, and only going like once a week, once I got over my tendencies around 13 or so years later.
