Fading Memories on a Lonely Bench Meaning & Interpretation

"In my dream, I walked through a park and saw my ex-girlfriend sitting on a bench. She looked up and smiled at me just like she used to. I sat down next to her, and we talked about old times. Everything felt warm and familiar, as if no time had passed at all. But when I reached out to hold her hand, she slowly faded away into thin air. The bench became cold and completely empty. I sat alone under the quiet trees, holding an empty space in my hands. A deep, heavy sadness settled in my chest as I missed her all over again."
