Psychologically speaking, there are many theoretical schools of dream interpretation, and psychoanalysis may be used to starting with sex, complex and subconscious; Image analysis is used to paying attention to symbolic meaning and image; Some psychologists pay more attention to the emotion in dreams than the content, and so on. However, from a psychological point of view, no matter what kind of dream interpretation is, it is believed that it cannot be interpreted only from the plot of the dream, but must consider the dreamer's personal information, recent experience, memory association of the plot of things in the dream, emotional feelings in the dream and so on.
So I don't know your age, sex and other basic factors here, so I can only talk casually, so it's not surprising.
Simply put, this dream of yours seems to give me a projection of your working and living conditions in real life. Of course, it may be distorted, but on the whole, I personally think that the emotions in your dreams reflect the negative emotions in your recent work, such as the pressure and anxiety in the face of important time, the anger of being bullied, the cheapness and deterioration of friendship, and the loss and avoidance of not being supported by friends. In fact, all kinds of unhappiness in dreams are the outbreak of negative emotions in real life. You said that you just started working, and it is a completely different change from school and family to social units, which requires a rapid change in your mentality, ability and experience. This change will inevitably bring stress, and correspondingly bring negative emotions such as anxiety, depression and anger. In reality, we have to suppress negative emotions in front of leaders and colleagues, but these negative emotions will accumulate in the subconscious. Therefore, if we can't adjust ourselves well, our mood will gradually deteriorate unconsciously under the influence of the subconscious.
In dreams, these negative emotions suppressed by the subconscious will gradually become active, forming a dream without sober and rational constraints. In dreams, we unconsciously invent a series of familiar or impressive scenes to cater to subconscious emotions. This is your dream.
In a word, dreams are just a projection, a catharsis and a distorted emotional release. But from the perspective of dreams, we can sometimes see more clearly the areas that may be overlooked in our hearts. From this perspective, the dream is a flash of lightning, which instantly illuminates our hearts at night.
