Ghost people and reoccuring dreams

So last night I had a dream that I know I have had before. The dream was really lucid and it was brielfy lucid the last time I had it. This time I saw a group of shadows or shades that were barely visible and shaped like people. I walked down some steps away from the house I had just exited, opened a metal gate, and walked through. One of the shades moved away from the group that I could see, and started walking away. I called out "hello" to her and she slowly turned visible. As she moved she was hovering over the ground like a ghost. She had no emotion on her face as she turned to look at me.
It was only when I woke up that I realised the last time that I had had that dream, I was her. I was the shade girl. I dreamed the dream from her perspective the first time around. I saw myself doing the exact same things that I had just done. I even heard the squeak of the gate opening both times.
