Everyone and everything has energy , this means each intuitive is different and has different levels of frequency that vibrates at different levels which means every intuitive will pick up on different information or some none at all . This means it is how we access and process the information we receive when a connection is established. This could also mean that the information may be limited. Not all two psychic mediums are the same. What one person picks up may be different or more detailed , it is just how it works.
Not all spirits wish to connect or communicate. Some spirits will connect only with a specific person or people. This means our loved one may not want to connect with that person or the intuitive providing the session, and sometimes they will connect with anyone and be chatty. It depends on if a connection is established.
