It seemed to bet set in high school, and the earliest part I remember was being in band practice. The director told us all to open up one of several books in our folders to a piece titled "Millennium". (I'm not even sure if such a thing exists, but if it does, my brain isn't familiar with it so there's no meaning there.) However, many students in the band soon found that the 3 to 4 pages that would have contained that music, alphabetically by title, were ripped out of their copies of the book. So were mine. And during a bunch of frustrated discussion like "who would do such a thing?" I noticed that the band director's copy was missing its pages, too. In the back of my (dream world) mind I was thinking... "Wait, so, you wanted us to rehearse something you clearly haven't even tried to lay eyes on, since you didn't know your pages were missing?"
Next part I remember, I was walking down the halls of the school with a bunch of other students, probably from the band, and we were teasing each other about birthdays from the perspective of who is older, and one of them told me something like "well since you'll die later, your body will continue its gravitational pull on the oceans for a longer time than mine", which makes no sense at all, but whatever. I don't think it was anyone I had respect for. :)
Apparently the discussion was so heated that they had all stopped moving, but I actually had somewhere to be so I broke free and walked away from them. I passed some sort of teacher walking the other way towards the crowd as he gave me a look and pointed as if to ask, "what's going on back there?" I just shrugged and said, "I dunno, talking about death or something," and kept walking.
As I turned one corner of the hall, I encountered two students who were trying to throw some kind of contraband to each other across the hallway, and somehow I immediately recognized what they were doing and had no desire to interfere, so my automatic behavior was to crawl on the ground to pass between them so I wouldn't obstruct their trajectory.
Further down the hall, I noticed a student who had just received from another student what appeared to be some kind of drug-laced English muffins. They clearly had something pink injected into them. As if a student carrying a pack of English muffins will be less suspicious than the drug itself? Plus, I can't imagine it's a very tasty combination, even though I have no clue what the drug was supposed to be, but I imagined it tasting like cough syrup.
As I turned a corner to head up some stairs, I saw Jon Stewart coming down them muttering something like, "oh, my poor broken heart." I guess he was supposed to be one of the teachers there. Another teacher seemed to be consoling him, and I asked what was wrong. She just gestured up the stairs to the higher floor. Up there I saw someone who was supposed to be Jon's wife. Although I'm not sure what Jon's real wife looks like, this person looked something like Kirsten Gillibrand to my waking mind, but in my dream I just recognized her as Jon's wife. Clearly she had just done something to upset him. Maybe they had a fight.
It's difficult to describe the configuration of this staircase, but somehow between Jon at the lower level and his wife on the floor above, there was a landing or something with a ledge at the height of window sill that was just big enough for a sculpture that I recognized to hold special meaning for Jon and his wife. It was some kind of puzzle made up of about 20 large pieces, and its completion was supposed to symbolize their love for each other (I know, cheesy). I don't recall anything about the overall finished shape of it, but I decided I had to remind her of it and make her rethink whatever she had just done to Jon, by taking a piece out of the puzzle and giving it to her.
However, this puzzle was also somewhat like a game of Jenga. Taking the piece out would be difficult without the rest of it falling. Sure enough, one of the larger pieces fell out from above the one I tried to remove. It appeared be only a surface piece though, and not one that goes all the way through for structural support. As I tried to put the piece back, suddenly the whole thing became snow-covered. I guess I wasn't in the school anymore. I was still trying to pound it into place and wipe the snow off of it when the alarm went off.
