When a psychic tells you something unprovable?

What could be worse when you are told of something that cannot be proved any where, not now, not even in the far future?

I am one of those who need to see proofs to believe.
I believe in God, but it is different.

Beliving what a psychic says needs evidence in real life.

A reading that I had long time was about my past life.
The lady from psychicsource.com began to talk about  my past life immediately after she picked up my call.
She described how I died in some centuries ago, and  how lonely my life was after my husband in the past life left my family.

She used to be the one that I called very often, but I never called again after that.
She is nice, or whatever.

However, it is a ripoff when you just feed your customers with loads of information without asking what they need first.
