I have had some pretty wild and vivid dreams since Bob died. Do I think that they were from some higher power? I'm not sure. I think they were what I call, "wishful dreaming". I can remember one in particular that happened near the 5th anniversary of Bob's death, in which I was chasing him all over a small town, with hills and valleys and there were huge traffic jams. He was in a small yellow convertible and when I would just get up to him, he would vanish around a corner. I remember how frustrated I was getting as I had chased him all day. I finally caught up with him on a ferry, and after I got in the car, he reached over and held my hand without looking at me. Then he said, "as much as I love you, I have to go". Prior to that dream, I was beating myself up that I wasn't further along in my grief journey than I was. I kept telling myself that I was holding on to him too much, and couldn't let him go. So, was this dream from a "higher power" or guilt? Who's to say.
I don't think musical preference tells you anything about a person. Most people would be shocked by the music I listen to, never thinking that I would be a fan. I do think that if a person likes music or not tells you something about them. To me a person that listens and enjoys music is someone who can think for themselves, with imagination.
