What there really are ghost??????

Psychologists studying religion have long suspected that a belief in the paranormal can be a kind of shield from the even harsher truths of the world. The idea is that when something unexpected happens – a death, natural disaster, or job loss – the brain scrambles around for answers, looking for meaning in the chaos. “It’s such an aversive state that if it can’t gain control objectively, we will get it by perceiving more structures around us, even if they don’t exist,” says Jennifer Whitson at the University of Texas, who studies pattern perception, and judgment and decision making. Even simply asking people to remember a time when they felt out of control, can make people see illusory forces at work, she has found. That included seeing patterns in the random movements of the stock market, for example, but it could also manifest itself by linking two unconnected events, such as the belief that “knocking on wood” for good luck would improve your chances in a job interview.
