First, there is no doubt that the negative performance of this dream shows that your recent mental state is mainly negative.
Secondly, in my opinion, this dream is related to physical health, which is mainly manifested in three aspects: first, the death of a classmate, which is a manifestation of kidney qi deficiency; Second, disasters such as fire show that the body is dominated by fiery evil, and it is suspected that it is a virtual fire; Third, crying in dreams is a manifestation of lung qi deficiency.
Third, if the above situation is linked, it is that the lung and kidney are not harmonious, and the possibility of yin deficiency and fire is high. You should combine your own reality to see if there is any respiratory discomfort.
Suggestion:
1, paying attention to your health is the first priority. Maybe your work and rest are out of balance recently, and people are tired, which leads to such a deviation in your body. Please adjust it in time and take medicine when necessary.
2, pay attention to the emotional situation, whether there are negative negative emotions, if so, please adjust in time.
You graduated from military school. When you have an iron will, please note that sometimes you have to retreat for progress.
Wish you all the best!
