Who will explain my dream? I dreamed that I found an empty wallet on the lost overpass.

You must have been waiting for someone. You said you didn't wait for him. What was the state at that time? Looking down, a man turned around on the overpass and saw an empty wallet. This is just an idea in your heart, that is, you failed with others, so you went home (I wonder why your boyfriend asked you to wait for him, but you wanted to go home because of the lost psychology). Finally, I got lost.
