Dreams are only a reflection of a person's recent emotional state and cannot predict the future. No matter what "events" happened in the dream, those "events" can be ignored, but the emotional state in the whole "events" process reflects your mood at that time: for example, dreaming of a car accident of a loved one can only show that you are worried about the recent safety of your loved one; Dreaming about the college entrance examination topic can only show that this is a student who is about to take the college entrance examination, and he cares very much. Similarly, when you dream that a snake bit you, the fear in the dream shows that there are factors that make you nervous in your daily life, and the "calm" expression of being bitten by a snake in the dream shows that you have been very comfortable recently. Watching horror movies or books before going to bed, there is horror in the dream. As the saying goes, "think about it day and night, and dream at night."
The content of dreams is often associated with feelings: if you have periodontitis, you will dream of losing your teeth; If you have it, you will dream of finding a toilet; If your feet catch cold, you will dream of walking in the ice and snow. . .
