Query: Bizzare babble

This is one strange book. That anyone takes it seriously proves that any crazy idea dressed in scientific sounding terms can be taken seriously if the reader is so disposed.How do you evaluate an author's credibility? It may help to know that Bradley now says that his theories came from vivid dreams that also involved missing chunks of time - experiences that he says are similar to experiences claimed by UFO "abductees" and "contactees". He also publishes guides for "survivalists".
