Whenever I sleep when I dream its always the same thing, either one of my friends or a family member is being brutally killed right in front of me. Normally the dreams start out normal, but then it turns into a hellish nightmare. I've even went to therapy about it but nothing came out of it. I want the nightmares to stop I can't sleep at night, which is making me lose my grip on reality. Also the dreams start out with me and a good friend, sometimes more then one, entering some strange town from hell. Well after that, its pretty difficult to describe.
Its not nessesarily true that your subconcious wants people dead, it may care for them and be concerned about the possibility of that happening.
I dont know, dont take things at face value is all I am saying, dont conclude that you are a bad person.
