WHAT IS A MEDIUM
Mediumship is the practice of purportedly mediating communication between spirits of the dead and living human beings. Practitioners are known as "mediums" or "spirit mediums"There are different types of mediumship or spirit channelling, including seánce tables, trance, and ouija
In other words, "a medium is someone who is able to communicate with souls on the other side"
A psychic isn't necessarily a medium, but a medium is a psychic. This is an important distinction and a good place to start, because I meet clients all the time who misunderstand the difference and confuse the two.
Psychics tune into the energy of people or objects by feeling or sensing elements of their past, present and future. Simply put, psychics rely on their basic sense of intuition and psychic ability to gather information for the person being read.
Mediums take it a step further. A medium uses his or her psychic or intuitive abilities to see the past, present and future events of a person by tuning into the spirit energy surrounding that person. This means mediums rely on the presence of non-physical energy outside of themselves for the information relevant to the person being read.
