I think most of the psychic readings are crap.
I have once learned to do psychic reading myself with Tarrot cards, and many actually wanted me to do the readings for them although I really didn't believe in it all that much.
When I was quite young, my parents once hired a psychic to come to our house to do some readings. He told us something that happened to my grandma (who's passed away at that time) that none of us knew about, other than my grandfather. We later verified that information with grandpa and it was true.
