It is considered that there will be some events in the life of the person who sees that he is sad and angry in his dream. The dreamer will experience negative things, will be unhappy with the effect of what he has lived for a long time and will walk around with a sullen face.
It means to pour out and relax. In the face of an event that will cause the dreamer to experience an emotional explosion, he gets tired of expressing all his thoughts freely, saying all he needs to say, and thus, he will relax and lighten himself.
