My mother was into these psychic readings back in the 70's. When I was a teenager I was into drugs and got in trouble a bit. So mother took me to see her so called psychic friend, who just gave me a lot of hoo-haw about my path in life: I could go this way and things will turn out great or take the other road and end up in a bad state. Nothing specific, just like later we went to other "mediums" who just seem to pull shit out of their asses.
She would bring a tape recorder to replay it later. They generally bring up vague things and get you to talk about it, that's all they need really. Power of suggestion combined with your vulnerabilities keeps them in business. Don't waste your money because like others have said, these people are only doing this for money.
On a lighter note, do you ever watch any of those mediums on tv? I have to tune in on the sneak because the old man has a fit and says it's all bullshit. But I like to watch even if just for entertainment. I would really like to believe my loved ones are watching out for me and I lost them all: fiancé, father, sister and mother. The only one left is my step-dad and son. If I lose either I don't know how I would handle it. I feel your pain man.
