There are many out there who are curious about the differences between a medium and a psychic. The common perception is that they are the same. Let me explain more from a professional point of view.
"Psychic" means the capability to detect and sense things that other people are not able to pick up. In other words, extrasensory perception (ESP, or 6th sense) which psychics have, in addition to their normal 5 physical senses. Yes, with this perceptional ability, psychics could predict what the future could be for a person seeking advice.
"Medium" means a person that is able to communicate with the spirits of the dead. We are talking about spirits in the afterlife. Usually, the medium will act as an interface between the spiritual world and the physical living person. Spirits can refer to the deceased, angels, and even demons. In more extreme cases, the spirit is given permission to take over and speak or write through the body of the medium.
That is the main difference between psychics and mediums. The only common link is that they are both functioning at the higher plane of the spiritual world and have sharp spiritual perception.
Personally, I have great deal experience in psychic and medium. Both are challenging professions that help fellow humans who are in distress, and I am proud to be able to offer my help.
