They can read you like an open book. They know what you think and what you do with your life when you do not. They are clairvoyant!
They use crystal balls, cards or other some special methods to probe your mind.
They sometimes need a bit of your skin, your blood or a strand of your hair to be able to connect with you.
Whether this is Guru Joe, Mindsreader or another being able to read you, it is always impressive to see a demonstration of this type.
