Gamer dreaming

Another crazy dream...
Much of it was forgotten by the time I woke up, but it became distinctively memorable when I walked into a kitchen-esque environment, only to find myself working with my older cousin, Adam, who I've not seen for a long time. I was remeniscing with him, laughing, organising some time in the future to catch up when this fat, brown haired woman comes into the room and starts shouting at everyone; so I assumed she was the boss.
She approachs my cousin and I, and asks him to open his bag. When he does, she discovers a container of steamed vegetables; carrots, peas, corn, etc...
She asks him to explain himself, and he tells her that he was simply going to take them home but replace them the next day because of a lack of shopping supplies in the house.
She proceeded to fire him.

I do not know what my dreams mean, or why encrypted mental projections chose to manifest themselves the way they do; but at this point the dream gets interesting.

My cousin (looking rather defeated) took his things and walked out of the kitchen. I was furious. I was mainly so angry because I had finally wound up working with someone I knew I could get along with, and now she had taken that away from me, but also because it was not only my own flesh and blood, but he hadn't done anything that bad to begin with... So, for reasons unknown to me, I picked up the white and red broom, started shouting insane, insulting rambles at her; and cracked her over the back with it.

And for what seemed like a really long time, I drove my fists into her face again and again and again... I ripped out her hair, clawed at her eyes and just; beat the fuck out of this fat, ugly woman... All because she fired my cousin? As it happened, as I was shouting and beating the woman, I was crying and laughing, like a crazy person.
Then I became aware that the cops were coming, so I ran. And as I ran, I realised that what I had done to that woman would land me in prison, or a fine; but I was pretty much fucked. So I just kept running and running and running, climbing buildings, and dodging in and out of the public eye. I remember getting onto a bus, and seeing the cop car with its sirens blazing go past me, wondering if they were looking for me or not. And I just kept on getting further and further into a suburban landscape that I had no memory of, until I thought I was out of there searching zone... Then a phone call at 4am woke me up.

Vampires, Zombies, Werewolves and police chases... Why do I constantly dream about violence and danger, my subconscious thoughts always seem so fucked up and odd. I don't understand why I have to run around so much in my head- when I wake up I feel more exhausted than I did when I went to sleep!
Maybe I do game too much.
