Makes mostly true but undocumented predictions, or well-documented but mostly false predictions.
I can understand your knee-jerk skepticism, and I can't speak for this lady, but prophets have and will continue to exist. Doubting their existence, doesn't make it any less true.
The Holy Spirit works through people to accomplish God's will. Padre Pio (a famous stigmatist priest of Italy) heard Karol Wojtyla's confession and told him that he would be the Pope one day. Karol Wojtyla, of course, took the name Pope John Paul II in 1979. Padre Pio had the unique ability of looking at someone and knowing their sins. There is lots of "documentation" as the Church can be just as "skeptical" in reviewing these types of things.
Luv it!
