Put a person in a sensory deprivation chamber, and within minutes he will start to hallucinate and become incredibly suggestible. Likewise, put a person into a situation where his senses are overloaded with non-coherent information, and the mind will go “numb” as a protective mechanism. It gets confused and overwhelmed, and critical faculties no longer work properly. It is in this weakened state that people become very open to suggestion.
