I always dream that I am on a high place.

Freud's psychoanalysis holds that dreams are the representation of human subconscious and the disguised release of "ID". The principle of human id is to pursue "happiness", but due to the influence of social norms, ethics and morality, it has been suppressed for a long time and can only be expressed in disguise by means of dreams. The pursuit of happiness by the id mainly follows three principles, which can also be said to be three kinds of happiness instincts: one is sexual instinct, also called libido; But survival instinct, that is, from the heart to do everything possible to avoid disaster or danger; The third is the death instinct, which is mostly manifested as cruelty to animals and others, thus making oneself happy. People have these three instincts, but they are suppressed and buried in the subconscious for a long time, and they can't get rid of them. Your dream is obviously a disguised release of survival instinct, and there is nothing to worry about. Standing on a high place should be scary and exciting. It is obviously a general principle and law that I follow in my pursuit of survival and happiness to feel relieved and inexplicable sense of security and pleasure after leaving my dream. I advise you not to trust Duke Zhou. Western psychology is a more scientific and authoritative theoretical system. Typing word by word is by no means copying and pasting. I hope it helps you.
