Demons: An Eyewitness Account by Howard O. Pittman is a 1979 account of a near-death experience in which the author, a Baptist minister, claims to have been taken into the spirit world and shown the inner workings of demonic forces. The book is designed as a warning to Christians regarding the realities of spiritual warfare.
The book was written to complement his earlier work, Placebo, focusing specifically on the activities of demons in the physical world. Pittman states that as a result of this experience, he transformed from a complacent Christian into an active soldier for Christ.
