Journey Into Polarity's Mind

I'm in my apartment. It's day outside and sunlight is coming through the windows and lighting the whole room I'm in. I don't quite remember what I was doing; the computer wasn't on and I was probably doing my homeworks. Over the flow of the dream, I wonder if I'm awake or dreaming - eventually, at that point, I notice that the hand I had on the desk didn't have the ring-finger and the little finger (or, even better, most of the finger was amputated).
"Is it a dream? ...Yes, it is" - I get up and take a look around: I can feel the different feeling of the landscape, it isn't anything like the physical plane. It also feels a lot different from the other lucid dreams because, this time, I was holding complete control over the dream...
I think that I should try something that I planned to do: a shared dream. I focus my energies on the wardrobe, expecting to create a portal through it. I wait a few seconds before opening the wardrobe door, but there's nothing in it but some clothes. So I think that I should do something else than creating a portal: I try to summon my personal weapon, a green electric whip, but I don't even succeed in that. I try to summon fire to burn the floor, and still nothing.

I head out by the main door and all I see around me is unknown buildings. "I'm not supposed to be here, where am I? This isn't my city." - Indeed, the city looked a lot like Chinatown. There were very narrow streets, extending between shops and poor apartments. It's night. The shop signs are the only source of lighting.
I turn left to the first alley, then the world changes around me again.

It's still night. My level of awareness is slowly dropping. I'm in an arena, it looks quite ancient and arcane. There are demons approaching from every direction. They have got purple skin and an armor covering their heads, shoulders and legs. They're led by a bigger, flying demon. It's got a dark armor covering its whole body and it's got devil horns.
As they surround me and they're about to attack me, I jump high in air and fly away. The landscape is very big: it's an huge dark purple wasteland with a purple sky and purple lightnings.

I don't recall anything else.
