Monsters, Death, Demons, War, Violence, Crime, Disasters and Afflictions... that's the short list. Nightmares are unique to the dreamer.

"A person's creations are extensions of who they are and can have a life of their own." - p. 26

Bio: J.M. DeBord, the most trusted name in dream interpretation, is a best-selling author of several popular books about dreams, including Visible Ink Press’ The Dream Interpretation Dictionary: Symbols, Signs and Meanings. Known worldwide for demystifying dream interpretation and answering all questions about dreams, what they mean, and why we have them, he is the resident dream expert at reddit.com.   

Examining common themes and symbols in the dark dream, Jason also addresses dreams with paranormal or PSI, prophecy and contact with supernatural others. He includes a personal element in offering his own nighttime horror story - terrorized by a a frightening entity that stalked him for 30 years. Even more sinister was the sense this being had the ability to interfere with activities during waking hours.

Almost at the point of giving up hope on ever getting rid of this nasty parasite, a shaman intervened, identified the source and the entity was finally cleared.

Best not to underestimate the harm sleep intrusions are capable of, nightmares have consequences. Learning to identify the source and get outside help, if needed, can produce powerful psychological freedom and release.

"Fear--it's the source of many nightmares, and the dream author has countless ways of symbolizing it." p. 272
