Reoccurring dream about a faceless man playing the cello, what does it mean?

Since I was 9 years old I have been having a reoccurring dream about a faceless man playing the cello. I have the same dream all the time but with more detail as well as small variations to the dream each time. The first time I dreamt it everything was in black and white and a bit fuzzy. Now, when I have the dream, I dream it in color and the textures of the things around me are almost palpable. The dream itself is now very realistic. I wake up feeling as if I went through it all. It's scary. My dream for the record goes a bit like this: I am walking down a long corridor littered with doors, when I am walking down this corridor I am walking as if I am looking out into the corridor from my own body, not from an outsiders point of view. As I am walking I reach a red door at the end of the corridor. As I slowly open the door there is a man with long black hair playing a blood red cello furiously. The room is dark and the only source of sunlight is a tiny window on the brick wall in front of him. The light shines on him as if it were a spotlight. As I walk towards him I touch his shoulder and he stops abruptly and slowly turns my way. To my horror he has no face (no eyes, mouth, or nose). He then proceeds to take my hand and lead me towards a door that opens to a field of red wildflowers. Variations to this dream have occurred. The only part that changes is when I enter the room. One time I was crying and he wiped my tears away, another time he was chasing me, and another time he just looked in my direction. This dream has been freaking me out ever since i was 9. I'm nineteen now. Freakiest thing to happen to me in real life was that one of my friends showed me a picture that he says is well known in South Korea of a man playing the cello in a room with a single window. The picture is in black and white and I have NEVER seen it before. The picture is just like my dream. What does my dream mean? I'm scared.
