Hello, let me help you answer.
First of all, don't have a psychological burden on this dream. What you should care about is your physical condition.
Dreaming of bloody scenes in a dream, with fear, on the one hand shows that you have been under great pressure recently, on the other hand, it shows that you have yin deficiency of liver and kidney, and dreaming of a lot of blood shows that you have liver fire or blood deficiency. Of course, this diagnosis is not comprehensive enough. If you feel obviously unwell, you can see Chinese medicine.
Physical discomfort will make obvious information hints in dreams, so we should actively adjust our psychological state, but we should not ignore the balance of physical state.
