Does evoking spirits lead to hearing voices?. How do spirits and demons communicate
Depends on the spirit and more importantly on your skills. I have experienced loud booming voices coupled with flashing lights and moving air in a closed room, all received through my regular hearing, sight and touch. It was very intense, and not representative of my usual experience. What I usually experience is generally a knowing of the answers I seek, often receiving the answers at the same time I ask the question in a download fashion.
I don’t hear voices. Only in my mind. Sometimes I wonder if it would be a good thing to develop clairaudience like that, or if it would be a bad thing that would drive me crazy. One time, one of the first times I tried evocation, I think I got close and heard some static, after that, no, with the exception of the time I did a messed up banishing ritual that was really an evoking ritual.
