The explanation on the first floor seems to be an in-depth study of dreams, but it is actually a nerd. The dream of a nation is not only related to the collective subconscious, but also related to the cultural traditions of all ethnic groups. You can't copy the conclusions of the masters, let alone their conclusions. These conclusions are preconceived. Now it can be proved that Freud basically chose dreams according to his own subjective understanding, and there is a great possibility of dream forgery. Although his theory is reasonable, many of his conclusions about dreams are incorrect. For example, Freud believed that tooth loss was related to circumcision, which was aimed at circumcised people. This is not the case at all for people who cannot be circumcised. In addition, according to the theory of collective subconscious (Jung), Freud's explanation is undoubtedly wrong.
As for the dream mentioned on the second floor, it has no influence and is completely subjective. What you don't know and think is mysterious is regarded as "superstition". There are many such people who insist on materialism on the surface, but actually fall into the quagmire of agnosticism and eventually oppose materialism. Dream is a function of the brain, which is materialistic, interpretable, useful and meaningful, but its meaning is still difficult for us to understand for the time being. People who interpret dreams must not be confused by "no symbol". Dreams come from human history and collective evolution.
The mouth is an organ for eating, and dreams imply life; There are teeth in the mouth, which means people who help life and overcome difficulties, that is, relatives and friends; Tooth loss is a symbol of relatives and friends leaving. In ancient China, because of the narrow living space, parents were the main helpers. People thought that losing teeth meant losing parents, which was reasonable. Up to now, the living space has expanded, and the people who help life have expanded to ordinary relatives and friends, which is also very correct. I suggest that people who study dreams pay attention to research methods; Suggest that people who think that dream interpretation is meaningless pay attention to your fundamental position. It's not that I criticize you: it's all problems.
