Have you ever had a dream, in which you feel very real and have to remember and remember very important things, but the moment you wake up, it slowly becomes blurry, and in the end you even only remember that you had a dream, but the specific content of the dream is unclear; have you ever been to some place, which you have obviously never seen before? You have been here before, but you feel like you have been here; have you ever encountered something that you have never experienced before, but you feel like you have encountered it; have you ever had some special feelings, when you are about to be unlucky or something big is about to happen, you will feel uneasy or irritable in your heart, but you cannot stop or change it. In this book I will answer them all for you.
