Now I'm enjoying this book translated in Japanese, 'Demonic Foes: My Twenty-Five Years as a Psychiatrist Investigating Possessions, Diabolic Attacks, and the Paranormal' by Gallagher R. The various possession phenomena are surprising. I'm interested in the cultural difference in the appearance of possession phenomena. I haven't heard body torsion or speech in ancient Latin or Greek languages in Japan.

Demons are horrible and pesky. But is my understanding incorrect that living human beings are as scary as them? War, physical violence, discrimination, sexual abuse, environmental pollution, and corruption of power... Anyway, this book is related to my research field. I'd like to know what they are and what they want to do. And if they exist, do "good beings" exist too???
