I believe no one in his right mind could believe in this, ...untill you meet someone that you never saw before and still this person is able to tell you the color of your room,how many rooms in your old house, the color of your ex girlfriend hair etc...
This is a gift( curse?) and they use cards or numbers just to put some logic in it and not to scare you, but actuaaly they could just look at you and still be able to read directly in your mind

Hard to believe i know, thats why you cannot try to convice people , its something you need to experience by yourself.

But i still believe no one should know his futur as it come at a cost for your sanity
