Your ex-girlfriend came to you because you still love her in your heart and want her back.
The place where you first dated means that you want your relationship to start over.
Kissing for dinner means that you want to be close to her and live with her.
She said she was leaving, which is a reality. She left you.
The elevator symbolizes her life, and men bully her. This is what you're worried about.
I was worried that there would be other men in her life, so I hit them and vented my dissatisfaction on the one hand.
On the other hand, I hope she knows how much you care about her.
Finally, you cried, which came from sadness or anger in real life.
Vent it in dreams, because it is suppressed in reality.
In fact, you sent her away in your dream, which means that you also know that this relationship can't stay, so you will cry so sadly.
