I almost don't want to say, some of you might not like to know this, you know it happens, but think it is only in extream cases. it is the normal condition in your life and mine. you are likely not alone in your body. the dead who don't cross over seek out person who they can inhabit, some by design, some are by accident, but you reading this are likely occupied or influenced by someone or several ghost. most are harmless, but if you are intuitive, guess why? you aint alone, you can hear and even see things threw who's eye's. do you wonder why you think you were reincarnated??? well maybe it aint your memories. the point is, this ghost, driven in anger, not thinking slipped into this doctor, and really messed him up, this doctor was brought to Dr. wickland, who with a electrical treatment forcefully removed the spirit, where the spirit was "long story" placed within another trained sensitive and brought to understanding about what has happened to it, in short, they converse... extreamly interesting and very funny... a must read book...
