Oh killing dreams are great. Mine are so vivid i can look into bullet hole wounds and see pieces of a person skull all over the floor while the guys blood is oozing out of his head. And its kinda of strange because i have no remorse when i kill in my dreams. But the people i kill are trying to kill me in the same manner, we are all soldiers with big ass guns. All non lucid to.
I can’t recall having masskilling dreams, however I have a recurrent dream that I’m in a knife to knife battle against a person I don’t like very much. But it’s been a while since I had that dream now that I think about it…
