Thanks for sharing your experience. Stories are how we make sense of the world, and the world doesn't always make sense, so some of our stories naturally veer into fantasy. The first question I ask when someone tells me a nonsensical story is how is this story meeting this person's needs? And could those needs be met in a better way, in conversation? Oftentimes the person just wants to feel heard, recognized, or like they're important. Once they feel these things, it becomes much easier to challenge their story on logical/factual grounds.
