I believe that psychics have their own way to convince people on their supernatural ability, it is clear enough that god and only god who knows about the future, and no one in this whole earth could predict the things that will happen in the future, even though if it happened by coincidence it does not mean they really know it.
They can tell you things and that depends on your way of thinking, they have the ability to study your mind very well and build their reading just from the things you provide them. They ask you questions that are very important to them in order to give you the things you like to hear!
I only believe in the sixth sense in which a person have a strong feelings about something and later on he discovers that those feeling were damn true!
Do you have a sixth sense? What was your experience, and how do you feel about it?
