The book is aimed at all readers, not just those who are interested in the esoteric arts. It presents, in an accessible and surprisingly clear way, the causes of the toxic associations that arise between people and ghosts. Ghosts are the souls of people who, for various reasons, overlooked their own death, did not have the courage to depart for the other world, or were detained, or even dragged from the road, by their dear ones weeping for those souls. When they remain in the world of the living they possess people. The presence of ghosts within a person causes powerful mood swings from strong negative emotional outbursts to profound depression. They evoke powerful anxiety attacks, persuade those who are possessed to commit suicide, have strong influences on the psyche, and are the cause of mental illnesses. Additionally, the physical illnesses of the person who died are very often transferred by the ghost to the person possessed.
