In 1966 the son of Bishop Pike committed suicide. After his death, Pike contacted the British medium Ena Twigg for a series of séances and she claimed to have communicated with his son. Although Twigg denied formerly knowing anything about Pike and his son, the magician John Booth discovered that Twigg had already known information about the Pike family before the séances. Twigg had belonged to the same denomination of Bishop Pike, he had preached at a cathedral in Kent and she had known information about him and his deceased son from newspapers.
Another important distinction is that while psychic readings often focus on predicting future events, mediums primarily tune into past and present issues. It's my opinion that predicting the future, while sometimes helpful, runs the risk of disempowering people. Always remember that you do have a say in how your future unfolds. Despite what any psychic or medium may "see" in your future, it is important to remember you were given the gift of free will when you came into this world, and at any moment in time you can absolutely redirect your course and create the life you want by changing your thoughts and actions. Psychic information is often just insight into what potentially could happen based on the road you are currently traveling—and it should be used only as a guideline to help you make the best choices for yourself.
Senses used by mental mediums are sometimes defined differently from in other paranormal fields. A medium is said to have psychic abilities but not all psychics function as mediums. The term clairvoyance, for instance, may include seeing spirit and visions instilled by the spirit world. The Parapsychological Association defines "clairvoyance" as information derived directly from an external physical source.
