Train murders and then a concert

Date: 11/29/2017

I first dreamt that I was on a train. I might have been Lucid, but I'm not sure. on this train, multiple people died a la Murder On The Orient Express. I "woke up" (false awakening) before any detective work happened. After my false awakening, I dreamt I went to a concert with one of my friends. There was only one man playing, and he wasn't any known musician, as far as I can tell. After he finished playing, he turned into what I can only describe as black goo, and "danced" by flying around the stage. I vaguely remember him mentioning that he is evil, but nobody ran away or left. Immediately afterwards, it was announced that he would be signing things. I had brought my guitar to be signed (it wasn't my actual guitar as this one was a green Stratocaster, mine is a red Les Paul), but he didn't start signing until after he had eaten what appeared to be oatmeal or porridge while still standing onstage, still with guitar around his neck. I got worried because I though my guitar had been stolen, but it was just behind me. Right before going up to get it signed, I woke up to my mother telling me I was late to class.
