Evil self?

I awoke in my dream I got up and got out of my caravan like thing. As I got out I felt something in me saying theres a dark entity inside. And suddenly I got angry and I punched the door (wich is completly blurred glass) with my under arm, and suddenly I see this utterly back shadow arm doing the same, wich made me furious.

So I trew open the door went inside and saw this head in bandage peeking behind the wall next to my door in my room. So I rushed inside and screamed "Where are you?!" Then I hear a noise coming from below i look thru some hole in the floor with a hatch over it, and I see someone drowning children. I get down and apparently i suddenly live above a tank station. I got inside, but I'm stopped at the door by this robot woman. She tells me that my darker side who called himself Armede II (in my dream my name was Armede Pronounced Armedeh not Armeed) got out of me and is now on the loose, hurting and killing people. So I yelled, and he came. But he got is arms around me and he was damn strong in this position he could break me like a twig, he was pinching he arms together a bit and it hurted like hell. So I didn't dare do to a thing otherwise it would be over for me. In this position he was talking with people about who he was and how he came to be (he was a demon and didn't come out of me but instead he fed himself with my "evil" side. Suddenly it seems to reset and I was again walking towards him ready to attack so now I hold back his arms wich are tryin to get a hold of me and push them away, punch him in the face a few times, he falls back into a rack. I keep kicking and punching till he falls again in some seat, where he grabs my legs. I start punching him with the bottom of my fist in his face time after time, his mouth full of blood swollen eyes yet he doesn't give a sign of pain instead he just laughs it off. He wants to put his bare feet in my face to poke out my eye (I know funny right?), so I almost bite his toe off wich did made him scream of pain. While being in this position he was saying over and over "I'm Armede II, I'm you but a better version, you can't defeat me" While he did this his name flashed in my head with all colors and pictures of where this demon was born and stuff.

It seemed I just kept punching him till I woke up for real

Sounds to me like you are exploring some kind of "shadow side". All DCs (in my opinion) represent aspects of what we think we're not. The most powerful ones are those where we have really very tight ideas about who we are. Your "Armede II" sounds like one of these, and if you want to get therapeutic about things, try and discover what it is about "him" that is so different from you and try and accept that you could be like that, if you chose to be rather than repelling "him". Again in my opinion, this reduces the power of the "demon".

The robot woman is interesting. Like she is someone who helps you communicate with your unconscious. What would "she" say you need to do?
(and what does this say about your feminine side?)
