Thanks for posting the video, I liked it!
At whoever said they didn't get why the dummies were there.....Here's what I got out of it. The ghosts are trying to live like they used to, and they introduce dummies & dolls into the scenario because they're fucking crazy ghosts! Hah, naw, but at about 25 seconds into the video, the old woman & the woman with the doll who's head has been smashed look at each other, and immediately look away after they make eye contact. Like they know they're living lies, trying to live the way they used to, and the woman with the doll feels especially exposed, so they look away to continue their pretending.
But what I thought that could be is a reflection of Alexi's (or the bands) drinking? "Ready for another drink anyone?!?" (Or does it say "anyway") Anyway, the ghosts are trying to be like they used to be, but it's all fake. Drinking a lot, and hurting yourself by doing stupid shit thinking you're Superman....Booze is letting you live in a dream when you're drunk.
The weird Chinese chick? I dunno, she's the hangover? Haha

I'm hungover so i'm not wording this correctly, but you get the idea?
Maybe i'm way off though & it's about McDonalds cheeseburgers or something, or i'm over analizing & it's just some crazy ghosts.
