6th sense and fortune tellers… is a generic term. These would be one of the following: clairvoyant (seers), clairaudient (hear), clairsentient (feel), psychometry (picking up psychic feelings through holding objects), precognition (knowing the future).
try searching for one of these terms on wikipedia… there’s a lot more. These are just off the top of my head. hope this helps. 🙂
