The event in question happened when the dinosaurs still roamed the earth, there's an emotional component, the story has been retold and thus rewritten repeatedly, and there's obvious factors of suggestion involved. So, what you're saying is, you were either the most incompetent psychologist since Freud, or you weren't one at all? Unless, of course you're immune to all of the factors that cause memory revision AND you've found a way to distinguish revised memories from real memories in cases where independent verification is impossible.
It's been pointed out that this specific case is a textbook example of how memory could be expressed, but you're all "nah, brah, I'm confident that it happened exactly how I remember it despite the fact that confidence in memory accuracy has zero correlation with actual memory accuracy". You may as well claim to be a retired physicist and say "trust me, brah, Newtonian physics holds at velocities near c".
