Is it possible?

To remember something from maybe 20 years ago? Out of nowhere I had this sick feeling and had vivid memories of this “game” my brother used to play with me. It was some bs game where he made up all the “rules” and I’d have to do a punishment if I lost. And the punishments were letting him look at my private parts. I was maybe 7 and he was 10 or 11. I just recently started therapy. Idk if that has made me remember things and be more aware? Either way, I’m so disgusted and glad we no longer speak.
