When I was younger, one of my friends' mothers was a Quija proponent. Supposedly, one session warned my friend away from going on a ski trip. We later discovered that the plane the group was supposed to take crashed. They also based the sale of their house on something the board said, warning them of an impending robbery (after three houses in the immediate area were hit over a course of a couple of weeks). They sold the house (his mom and dad had been considering it anyway, it wasn't JUST the board). Apparently, they kind of got screwed on the deal, getting stuck for a new roof - so, technically they DID get robbed on the house.
Admittedly, I do not completely rule the "supernatural" out, thanks to experiences with meditation and martial arts, but I tend to think of it as something internal rather than spirit pressure from the "other side."
That said, I think the only real danger involved comes from being so insecure/impressionable that one would actually ACT on something that came from the board. If you're to the point where you're planning your week based on tarot, quija, and viking runes, you've got issues.
