Was at work, at the furniture store I work at. The building was a tall, all glass building, probably 6 stories or so with an open center going the entire way up. In a basement level I was watching standup comedy with some friends I didn't really know. I was really drunk somehow and I was kidding around because there were like 6 people in the place, but it almost immediately turned into me heckling in a really crowded room. I apologized and went outside, sat in a car for about four hrs. The car was like a Disneyworld ride, where dinosaurs or whatever would come up to the car, smash the windows and scream really loud but it was obvious to me the sound was coming from speakers. After that I got out of the car to find it was now daytime, and in my head I thought "Well back to work". I walked into the furniture store, and my manager told me I had to help one of the "veteran" guys move something up to the 2nd highest floor. I somehow knew I had never been there. I was helping him dolly a regular couch up the steps to the 5th floor, when he told me he couldn't believe they were letting me go up there so soon. As he said that we looked out the window to see some people on the street outside walk up to the building and unzip themselves for a brief second to reveal they're various kinds of aliens or monsters. We got to the floor (which was a big open area with the opening in the middle and elevators all around the room) and arranged the couch we had brought up. Out of nowhere, a little kid climbed up out of it and just kind of loitered. I pressed the button for the elevator which we didn't take up for some reason, and a weird symbol flashed on a screen. I looked across the room and my coworker waved for me to come to his elevator, but as soon as I took a couple of steps it slammed shut and presumably went down. The lighting changed to alternating between dark red and green, and another elevator soon opened up revealing a large alien with a metal suit covering it's body. At this point I felt like I was in a video game and assumed I was supposed to hide and see what the alien did to the kid. But as soon as the alien turned it's back I sprinted and did a wwe-style dropkick to the back of it's helmet. It ripped it's helmet off, got right up in my face, and started screeching a really, really awful noise that sounded like large amounts of metal crashing and scraping. Again, I felt like I was back in the car hearing the screech through speakers. I ran downstairs but for some reason was certain I was mortally wounded. I stumbled around, smacking aliens to no effect and eventually found a room full of kids that was almost identical to the jedi children room in the star wars prequels. I woke up at that point. Also drove around and crashed a company bulldozer at some point, don't remember how that fit into it.
