First of all, you may be under a lot of pressure (including emotions) in your life, work and study recently, almost to the limit. I hope you can find out the reason carefully and adjust it in time.
Of course, someone has upset you, made you angry and unhappy recently, so this kind of thing happens in your dream. Beware of villains and pay attention to traffic safety when traveling.
Usually, when you are in a bad mood or too tired, you will dream that there is a white block on your good friend's back. My face is like a ghost. I feel the same way. In short, be careful in everything, be patient with people's contradictions and avoid quarreling.
The blood in the dream generally represents the mischief and trouble of the villain, and the others have no special meaning. )
Don't believe too much in dream interpretation, just live a normal life.
