Medium? Psychic? What a load of bullshit!
There is no psychic.
The guy should have watched "Mentalist" instead of "Medium". Patrick Jane would have told him that there is no such thing as psychic.
James Randi should have told him that there is no psychic. That he is either cheating himself or cheating others.
Here is the James Randi $1,000,000 psychic challenge.

If you know this is not real, but when to know about the mind set of someone who fake as a psychic, then go ahead.
Just to make it very clear. There is no afterlife. It is bullshit. So anyone claim to contact someone after he is dead, is either lying to you, or lying to himself, or both.
