Invasion Revealed explains the negative elements that invade our mental realm from a spiritual perspective. Harris calls addicts "dysfunctional people" but eschews the term "abnormal." She sees them rather as demon-possessed and urges them to take immediate steps to love themselves and drive out their own demons, which she says are actual translucent spirits that can control one's innermost thoughts. Alcoholism, drug addiction, mental illness, Alzheimer's and similar illnesses are caused by the individual's unintentional neglect and ignorance of the spirit nature of the Self.
