There is a distinct difference between being psychic and being a medium. Psychics are able to read a person's energy and gain information about their past, present, and future. Mediums take it a step further, tuning into non-physical energy. There are different forms of mediumship. During readings, mental mediumship can be used to bring healing messages from a client's loved ones in spirit.
Loved ones tend to show up during a reading if the client has been thinking about them a lot or calling upon them. If you are open to receiving such messages, feel free to make that known. If you are not interested in receiving such messages, make that known too!
There is no guarantee that loved ones in spirit will show up during a reading, or more specifically, the loved one a person wishes to hear from at that moment. Spirit is in charge of who comes through. The reader acts as an instrument through which Spirit is able to communicate. Often our loved ones come to offer support and healing messages. Other times they come bearing a message for someone other than the sitter. If they feel the sitter can deliver an important message to someone else for them, they will likely take advantage of the opportunity. Our loved ones in spirit retain much of their earthly personality even though they have transitioned to the spirit world. Unlike our angels and spirit guides, they still often like to tell us what we “should” do!
Protective measures are put in place before any session begins. An intention is set which protects all participants with the white light of the Holy Spirit. Archangel Michael is also called upon for his protective abilities. The intention is that only messages for the sitter's highest and best will be allowed to come through during the reading. Spirit is respectful about honoring people's wishes.
