You constantly went to bed as early as possible to meet the person from your dream again, but he did not appear. On this rainy day, you were lying and involuntarily fell into a short sleep, he was finally there. "I'll see you soon," his voice sounded. You've been thinking about this dream a lot. A week has passed, you haven't seen him in a dream since then, but now you saw him, alive and sitting opposite you in a subway car, does he know you?
