The man went into his own thoughts. This is a state in which you are on the verge of two worlds. The two worlds are sometimes alien to each other, the outer and inner world of man. They often confront each other. How you perceive it and how others perceive it. Sometimes there is a kind of cultural shock and imbalance in the balance of understanding of being. In this state, the world loses its color and many areas of misunderstanding plunge into the darkness of despair.
