I agree---and glad you to hear you feel you are getting as much as 25% information you don't already know (I assume info that is later validated) ..that's encouraging!
Some the readers that have spontaneously told me something I had no knowledge whatsoever of, that was later validated, are Uli, Skye and Narnia. (Skye is controversial to some, but from my experience she is as real as they come)
Having mentioned Narnia, who just blew my doors down with an out-of the-blue DETAILED 'pronouncement' of what this man was actually thinking --(which was diametrically OPPOSITE to everything I was hearing, experiencing and believing with every fiber of my being about him--and was proven TRUE within weeks) Although she was a rockstar with this, she has not been able to predict successfully for me beyond that spectacular time.
Anastasia (CP) and Gina Rose gave me a specific prediction that DID COME TRUE to the dot, within 2 weeks. They are both authentic.
