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.
The Medium makes connections with and delivers messages from people who are no longer living, to those who are still on the physical plane. In addition, Mediums can receive information from Spiritual Guides and Angels who preside in higher dimensional realities.
A Medium can be seen as a bridge between the physical and higher planes of existence.
