Supernatural Practices should be Avoided

 Sefer Chasidim (#204) He who involved in oaths of angels or demons or magical incqantations will not come to a good end. One should also avoid making requests in dreams. He will see harm in his body or children his whole lfe therefore a person should always avoid these things as well as asking questions in dreams and other supernatural practices since the Torah says Tamimim tehiye. They lead to harm including apostasy and sickness to himself or his children.Nor should he have others do thses things for him. Instead he should pray to G-d.
