I don't think anyone has control over such visions, but if someone has the "gift," don't knock it.
I don't discount the real, but very rare, gift of prophecy or foreknowledge.
I was knocking the frauds.
Your sister shouldn't be down on herself for not concluding that her "vision" was a fortelling of an imminent attack on the WTC. No other reasonable person would be. If this wasn't a coincidence, perhaps this was a sign to her for some future purpose.
Oh, I didn't intend to be critical. I know--everyone on the thread was knocking the frauds. I agree that a lot of the people making a living at being "psychic" are a bunch of charlatans.
Can you help, though? When I saw this thread, I thought I might be able to find some support for my sister from anyone else who might have foreseen 9/11. I know about the rap album cover, the Dutch calendar, and the NJ minister with the newsletter. Anyone else out there?
