Ex-boyfriend Under Yellow Streetlamp: Confusion Meaning & Interpretation

"I was inside a strange dream. I walked down a quiet street and saw my ex-boyfriend standing under a bright yellow streetlamp. He was wearing his favorite blue jacket. I called his name, but my voice sounded very faint in the cool night air. He turned around to look at me, but his face kept changing shape like water. One moment he was smiling, and the next moment he looked like a complete stranger. He reached out to hand me a small paper box, but when I took it, the box turned into dust and blew away in the wind. I asked him why we were standing in this empty place, but he did not answer. He just pointed down a dark road that had no end. I could not figure out if I was supposed to follow him or turn around and leave. Nothing in the dream made any sense, and I felt lost as I watched him fade into the mist."
