Hollywood Undead - Street Dreams Lyrics Meaning

I think this song is about someone spiraling into insanity.

"Again in the night, we go into the world unknown, just let us go." -This person, making bad choices and doing drugs/drinking alcohol, doesn't want the help of others. He's not interested in getting better.
"I know that I'm breathing slow, inhaling smoke, I just awoke." -He's just woken up and is already smoking something; he's ill and is breathing slowly, barely.
"A bottle of pills I'm chokin' down, with dancin' demons all around.
And I'm hearin' sounds and I know I'm hearin' voices now." -He's taking pills and he's hallucinating, hearing voices, seeing things.
"With all the buildings crashing down, it's Armageddon again.
I'll drink the poison from the ground and make a toast to the end." -He's dying, but he doesn't care; he's accepting it.
"For all the kids and all the ones and even some who've just begun.
To feel the pain cause they can't stand to stay away." -He doesn't want anyone to end up in the world that he's stuck in, but he knows most will end up like him, they can't stay away from bad lifestyles.

Chorus:
"I see the streets burn every time I fall asleep
I'm losing all my sanity
I can't hide from the voice that speaks inside of me.
I see the trees burn along with all my memories
I'm losing all my sanity
I can't hide from the voice that speaks inside of me." -More hallucinations which are now becoming dangerous. He hears voices, and he has visions, and he knows he's becoming dangerous, wanting to burn and hurt things now.

"I saw you walk into a room, I saw a face I thought I knew.
And all along it was true, It was me, it wasn't you." -He's probably in an asylum or rehab, some place that will help him recover. Still hallucinating, thinking he's seeing people. He's realizing that it wasn't anyone else's fault that landed him there, only his fault.
"I asked myself if it's the truth a guilty conscience isn't proof." He's not sure if that's the truth, if he belongs there, and isn't sure if they're just making him feel guilty for his mental instability.
"A fingerprint, well what's that do? Cause gasoline can burn that too." They might file him down as another patient, take his fingerprint, photograph, whatever, but he can burn it and erase any trace of himself.
"So hide your knives and save yourself. It's just you there's no one else." He's warning others that in his condition, he's a danger to himself, and he is alone in the fight.
"Will I change? The time will tell. Why can't I dream? What is this hell?" -He's not sure if he can recover and fix himself. In the meantime, he's stuck in hell, and he can't see anything good in his life, can't dream.
"So maybe I should stop this time and draw the line and see the light.
But it's too late, I can't this time. I've lost my mind so say goodnight." -He's going to hurt someone else, blinded by insanity. He's trying to stop and save himself, but he can't this time. He's gone insane, and there's no going back now.

"Who's to judge who's insane? Watch it all wash away." -He's saying that in reality, no one can judge who is insane and who is not, because there's always something sinister about people once the outside is washed away.
"Save us from what we've made. It doesn't die, it only fades." -People that have lost their minds need to be saved from the monster they created, but it never truly goes away, only fades.
"If I can't feel there isn't pain. Another day and it's all the same." -He's felt so much pain that he's saying if he can't feel pain, it's not there. Days are passing and he stays the same. His life unchanging.
"I always pray, I never change. It seems to me we're all to blame." -He doesn't want to change; everyone's responsible for causing pain of some kind.
"Meet your matches, no more rain. Burn this fuckin' world away." -He's finished with the world and is ready to burn it away, refusing to suffer depression ("rain") any longer.
