Do you have any memories that you can't determine if they are real or not? Possible TW

So I have a memory of a strange an inappropriate incident happening between my older cousin and me. I don't know if it's real or not. I feel weird if it's not. But I don't know if it actually happened or if it's just in my head. Do you have any memories like this? It's really bothersome to me.
