So many people do not know the difference between a ghost and a spirit. Spiritualists and those who investigate what is considered “paranormal phenomena” generally have an understanding that both ghosts and spirits really do exist but they are quite different entities which we are about to elaborate for you.
A Spirit is an energy that contains the fully conscious soul of a person. You are a spirit, here and now, and when your physical body dies your spirit is what moves on into the afterlife. A medium communicates with the spirit of the person who has passed over. A ghost is like a residual energetic impression that is left behind in the energetic matrix of physical matter.
Mediums can connect psychically to this energy. I could walk into a building and connect to the energy within that building and tell you things that happened in the building from the past. I would be picking up on the energetic imprint that is left behind. Some imprints, for the reasons just mentioned, are stronger than others.
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
Hollywood has been keen to relate to ghosts as a spirit of a person who has not moved over to heaven or some sort of afterlife away from Earth. This is simply not true. A spirit, who has not moved over to heaven and stays around Earth and this physical dimension, would be classified as just exactly that. A medium can’t form a two-way communication with a ghost, ask it questions, and get replies, etc., as it does not have a human level of consciousness. It is like a picture or a film of something that was once there, one that a medium can also pick up feelings from as well.
A medium can, of course, communicate with a spirit, ask it questions and receive answers back, etc. Other cultures have different names for different energetic entities, which can translate to mean various things in English. Often the language is so different and the closest word in English may be ghost, but it doesn’t mean what the other people mean as exactly what we think of a ghost as being. From my perspective, the way I have described is the best way to define, separate and categorize these two very different entities.
