You should read the book called the corruption of reality by Schumacher.. the idea there is that human beings are evolved to enter a altered state of consciousness during ceremonies and rituals combined with action and music, usually drums.. that's why you hear reports of primitive tribes in the past entering a trance State and writhing on the floor.. Professor Schumacher theorized that humans are evolved to enter such a trance state in order to regularly suppress their fear of death..
