I don't believe in any of that stuff. But I do think that things like this can be dangerous ,because suggestible people can be convinced of things which are not true, and which could cause trouble.
I always smile when people say they went to see a clairvoyant or whatever, and "she told me things that only I would know". If you read about how clairvoyants do their work, you'd understand that they make a study of people's body language, and know what people want to hear. For instance, if you told 100 people " others don't appreciate you", almost all of them would say "Yes ! That's so true about me !"........which is because everyone thinks they are unappreciated. And so it goes, and some people make a good living out doing this.
