Colin Dickey is great! In this book he brings up a lot of points that only come from somebody who has hunted, seen things he can’t explain, but… a natural skeptic.
He thinks things through and, in my opinion, runs a natural logic tree. Is the conclusion that ghosts are a function of a memory out of control a valid one? He is an experienced ghost hunter, pretty funny live, and has interesting observations. One observation, there is a lot of money in ghost hunting (again his sense of humor.)
He likes to research, really research, his sites and thinks about the paranormal on a deep level. One example is the Winchester House. He looked deeply into the legacy of Sarah Winchester. He says its amazing for how rich she was how little documentation exists. His conclusion was that she was not crazy, differently go around moaning or acting weird. No employees ever complained about her behavior. We know that she was a self- taught architect. It was her craft, she loved it, a lot of things she designed and builtwere experiments, not sexy supernatural, haunted widow pathological stuff. It was not, in his opinion, a manifestation of paranormal influence.
