Folk omens and superstitions exist as much as humanity itself exists.
Certainly, signs have come down to us from the farthest depths of antiquity, and having the most various forms and manifestations of national signs and superstitions, sometimes it is incredibly accurate to notice the true essence of the processes taking place.
Each of us faces daily with different people, gets into difficult situations and sometimes does not notice anything around us. The appendix contains articles on national signs and superstitions of life that tell about the meaning of signs. In any national culture there are various signs and predictions. About the existence of these signs knows, probably, each of us. Believing omens or not is a personal matter. But even those people who do not consider themselves superstitious, instinctively do not like to spill salt or meet black cats on the road.
By themselves, folk omens and superstitions originate from antiquity. When mankind on Earth still had practically no stock of scientific knowledge, it was folk omens and superstitions that were designed to give explanations to events that were not obvious. Since then, centuries and even millennia have passed, but folk signs and superstitions have so strongly penetrated the human consciousness that even all the achievements of modern science are not able to limit the influence of folk signs and superstitions on human life. Even without realizing this, people follow the once established rules and listen to the signs that distant ancestors were guided by.
Signs are based on the principle of interrelation (often irrational) between some action and its result. Whistling - there will be no money, eating fish during pregnancy - the child will be born dumb, catching a bouquet - next to get married, etc. No matter how strange the sign seems, it was born from observation. Several people regularly noticed for quite a long time how one event invariably leads to another. And the thought that these two incidents are necessarily connected is rooted in people's minds: there will be one — the second will come.
