The technique of seeing through the eyes of a demon. The demons see, scan a person or an event, a situation, and communicate the practice. It often happens in a dream.
Effects of psychotic substances. Usually these substances are of natural origin. In Russian shamanism, fly agaric is used to expand a person's consciousness and enter a trance and complement it with sound waves using a tambourine. On every continent of this planet, you will find many examples of how a person, inhaling or using something, rubbing himself with a special ointment-cream, entered a kind of trance. As an example, I will cite the works of Carlos Castenega, in which the name of the plant is clearly written and the visions themselves are described after eating this plant. As an example, I can cite the dangerous work Necromecon, which is now publicly available on esoteric sites in a very high-quality translation in Russian. The Necromicon presents the experience and knowledge of an ancient wizard who also used dried white beetles in the desert to see other worlds and interact with them.
Most people are big fans of chatting about nothing, gossiping, saying nasty things and condemning a single person behind their back. This is especially common in the era of the Internet and social media. Even the name is officially given to this phenomenon – trolling. All this is due to the fact that people believe that words thrown at another person's back inadvertently, of course, when this person does not hear them, do not bear any responsibility and of course they will not have consequences in real life. That no one would know what they would say. But what if I say that not everyone is like that?
