" Through paranormal investigation and communication with the souls of the deceased, you can add unwritten pages in history books through the voices that lived it. If you know what they went through emotionally then you’re putting your body and soul on the same historical plane with them. You are calibrating yourself to their time and spiritual energy. By knowing the history you can develop ways to get better evidence. You can think of paranormal investigation as a metal detector and the history is the battery. Without history to power you, finding treasure is nearly impossible. "
