Is it normal that my dreams are very very violent?

Almost every night I have wickedly violent dreams. In which I either am killing people or being killed myself. I can remember all of these dreams in crystal clear detail and often wake up physically disturbed by them.

Another odd thing is that many of them do feature zombies despite me not even having any intrest in the zombie stuff.

My dreams tell me that I'm a natural born killer (Not trolling or fucking around here). When I'm hunting this thought comes to me frequently and I've put down every animal in one shot. Clean through the heart and vitals every time as if I'm taking down a man.

Another thing is that in my dreams I vividly shoot people in the head, execute people, est. And most of the time it seems to be during a time of war in which America has been invaded and I have become a rebel fighter. I had a very hard childhood and a lot of pent up anger towards the people around me growing up if that makes a difference. I was suicidal and tried to take my life several times. My bro died of drugs, my parents were fucked up and did drugs as well, and I had 0 friends and 0 support.

tl;dr, my dreams are fucked up and i kill people vividly, and these dreams are actually impacting me as a person.

Sorry for the wall of text.
