You think, dream, this thing is actually caused by something you have thought about in your mind or done before, and it has been hidden in your heart, which belongs to normal psychological function. If you don't believe me, I advise you to sit down and think about it. Did you get beaten during the day and someone bullied you? Then you may have had this dream because of revenge. If not, maybe it's just possible to get some spiritual stimulation.
I hope you are not superstitious, but there is nothing wrong with superstition. China's deep-rooted mental state cannot be changed in a day or two.
You said you saw your teeth fall out in your dream, right? I'll tell you according to superstition. Losing your teeth in your dream is a good sign, especially when you see blood. In other words, dreams and reality are often contradictory. Don't worry, just do your thing. Life is alive, why think about these complicated things? Right?
Just be careful on weekdays, hehe.
