All that I can remember of this dream is that I went into a building, there were some other people there including my former male classmate WG, and at some point I left.
Later in the dream I learned that WG was dead, but I am not sure what happened to him.
I probably returned to the building where I last saw him maybe hoping to get some answers, but that is all that I can remember of this dream.
Somehow the man died and/or went missing, the police were doing an investigation, and his sister went to the building where the video was filmed to talk to the police who were investigating.
They asked her questions about her brother, and maybe they mentioned the possible white supremacy reference; and she said that her brother had no involvement with that as far as she knew.
But that is all that I can remember of this dream.
