If you are worried, you can recall what you have suppressed, what you can avoid, or what you have in mind. This is very helpful to solve the problem. And avoid touching anything that is too exciting.
Besides, drinking milk, combing your hair, soaking your feet and taking a hot bath before going to bed can all improve your sleep. Don't get too excited within half an hour before going to bed, and don't touch anything irritating.
To learn how to interpret dreams, we must first study psychology. Freud and Jung are masters in this field, but their works are obscure. The specific people Freud studied are not suitable for us, so beginners should not read their works yet. We suggest reading the books we have learned in The Study of Dreams, such as Psychoanalysis of Dreams, 500 Cases of Dream Interpretation, Dream: Inner Voice, How to Interpret Dreams, and Imager's Scientific Interpretation of Dreams. Dangdang can be found online.
As for China's ancient books on dream interpretation, I suggest you don't read them first, because China's ancient books on dream interpretation mainly focus on the prophetic function of dreams. People in ancient China, especially the masters, were as calm as water and sometimes had prophetic dreams. Modern people seldom have prophetic dreams, so you can't read ancient dream interpretation books first. Of course, if you finish reading the psychological dream interpretation books, you will find that the ancient dream interpretation books in China and the modern dream interpretation books have one thing in common: they all use symbols or images. It's just a different tense.
