Talking to spirit is about a psychic's relationship to their spirit guide or spirit guides.  It is a higher energy that the psychic is able to feel in a sort of energy form.  Sometimes spirits will send a quick number or string of words for the psychic to convey to the client, other times the spirit will send a feeling, such as calmness, a vibration or cool breeze to the reader to convey to the client.  These feelings can have different meanings to the reader then the initial thought of what the feeling means to us here in the physical world.
