Alter personality dream?

Hello. First off, i think i should say that i suspect i may have Dissociative Identity Disorder, which is possibly relevant to this dream. So i suppose it would help to know about DID to analyze this dream. If there's any questions, feel free to ask.

This dream was rather long, and i forget most of it, but i don't believe it was too relevant. But the part of the dream i want analyzed starts with being outside at night in a city, and there's all these people in a sort of 'city square'. I feel like a different person, and i feel this sort of dark aura resonating from me. I can feel an intensity in my eyes, and my whole being. I suddenly have the urge to go after these strangers, to attack them. So i start going after them, trying to get their legs out from under them. But they strike back everytime, and hurt me, and push me away. Then i go onto the next person. I believe i knew that response would happen from the beginning too, yet i still did it. It almost made me want to attack them even more. In the middle of going after someone, i sort of 'seperate' from myself, and am standing off to the side, and able to see this person i just was. No one notices me, and he just keeps going on with his business of attacking.

He looked like me almost, but with darker and longer hair. Everything about him was dark, including his aura and presence. I could just feel the intensity radiating from him, and it was in his eyes, and he had this odd grin on his face.

Suddenly i/we were in this lighted building on the bottom floor, almost like a lobby/sitting room/hall in a hotel or something. It started with me being this person again, from his perspective. I wanted to see the damage from the fighting. Then i was seperated from him again. I don't believe he knew i was there again, and he was looking at his wounds in a mirror/reflective surface. It's almost like most of the wounds were fake, or atleast went away quickly. There was only some blood and scratches on his face. I was at his side, and noticed something on the back of his neck, a bit off to the right. I looked closer at it, and it was a long, thick wound. It was almost completely black, and i wondered if it was a burn, or was healing weird or infected. It seemed like that wound was the focal point of the dream, like if the dream was a book, that would be the symbol of the whole story. But i didn't know where it came from, or what it meant. The dream ended after that, and i don't know if he knew about that wound. I was dying to know more about it, where it came from, and what it meant. And still am.

So that's basically it. As for the DID part of it, I have one (known) alter, Duke, and he is an abuser alter. I don't know the specifics of him, but i always had a feeling he was older, with darker/black hair, that was longer. He is pretty violent, and to sum him up in one word, intense. Understanding abuser alters would make one understand the attacking part of the dream i suppose.

I hate to turn this into a mental health discussion/question, but it plays into the dream so i have no choice.

I guess i am both wondering generally the interpretation of this dream, and if it was just my vision of myself and Duke (as in, it was still me throughout the dream, even when i was in 'his' body), or had Duke come out, and it was his dream (until i seperated and watched him).

Again, any questions to clarify anything, feel free to ask. I posted on this forum figuring it would be best since it's a dream site. A mental health site might not know as much about dreams.

Thank you.
