"Cube"-ish

This one might be connected to the dream of the previous REM-phase, but I can't recall the beginning of it.

I'm in a very short corridor leading to a large white room. There's also a group of random people with me. I don't regonize anyone. The room's floor is filled with rows of toilet seats (without the water compartment, just the hole and seat) from wall to wall. They form a tight grid, with no space in between. In the middle of the room is a white closet, with a door from the floor to the ceiling. The door is the only visible exit from here. One person from the group decides to go to the door. As she walks on top of the toilets, my 1st person vision changes to a "camera", that zooms into the lid which she is standing on. A spider crawls from the side of the toilet and goes inside it. A heartbeat later an insane amount of insects burst from the toilet and attack the poor volunteer. They engulf her and soon she falls to the floor as a twitching black mass of insects. Then I see two fast "cuts" from above of two other people dying from shark attacks (yes, a shark attacks from a toilet. Don't ask me why!) The first one is bitten in half and loses his legs. The second one is devoured completely in one bite (a nasty close-up, you could see the horrified look on his face and the remains of flesh in the shark's teeth presumably from its previous victims). The final cut is a moving panoramic view from the ceiling, showing even more victims lying on the floor. Some are missing skin, limbs, or are heavily burned. Some of them are still alive, but no one dares to help them. (presumably some of the "toilets" are trapped. Cube, anyone?)

The transition to the next "scene" is probably instantaneous, because I don't remember anything happening inbetween.

Our reduced group is in a square room with no doors. There is a window high up on the wall. It's not big vertically but it's as wide as the wall. I can see a parking lot, and some other buildings farther through the window. Everyone cheers. (If you've seen Cube, you can relate to the feeling.) One person begins to climb immidiately, but as he is jumping through, I shout "IT'S A PROJECTION!" (I realized that the scenery was just a fake picture projected on a wall or something, because when examined more carefully, it looked like it came from a projector.) I was too late, he had jumped through and we heard a loud splash. Hoping he not would be dead, we picked up a plank from the floor and pushed it through the window/opening to grab. He manage to climb back but he seemed different. Somehow everything just descends to chaos. People start to break the walls to get out. I go outside through a hole someone has broken. Everything is black. There is a small ledge made of planks surrounding the outside shell of the room, and after that, an endless sea of some murky liquid. The only source of light is a lightbulb inside the room, shooting weak rays of light through the holes in the walls. People are thrown and pushed in the "sea", and climbing back up to throw more people in. I reason that once you come in contact with the liquid you start throwing others in for some reason. I try to escape the madness by running around the ledge.

Suddenly three men in suits (à la Cube Zero) appear. The leader says: "Did you really think you could escape?" and snaps his fingers.

I wake up in a narrow cavement lying on my stomach. I begin crawling forward and see a cellar ahead. Before the cellar, there's a row of slowly rotating orange circles that float in mid-air (think coins from super mario etc.) Touching them makes them dissappear and adds time to the timer on my newly appeared "HUD". I get to the cellar, and collect more of the "time bonuses" I climb upstairs, but find the door locked. I don't have time to look for a key, so I kick the door open. I enter a home of a random retired senior. He's sitting on a couch. I must fix his computer before I can proceed (?!?). The computer has windows XP, and it throws a random error message at me when I try to boot it. Time is running out...

And I wake up. I didn't write the dream down or even check the time, so again it's just an estimate
