tvt, I tend to agree with your point, and in fact I made this exact same point near the top of this page. “supernatural” stories should not be “proof” to us about these things.
But, I don’t have a problem with repeating or hearing a story that has an important lesson, despite the fact that it may have an unusual twist to it. As long as one always keeps in mind that their emunah should not be hinging on the outcome of that story, for it may be false.
