Ah, I finally had a dream I could remember, but I didn't remember enough details to write much about it.
The first thing I remember is leaving my party of three while we were sneaking our way through this enormous, dark, and metallic complex for unknown reasons. I'd bet we were after some sort of boss-man. There was a big, tough looking guy (he reminded me of the TF2 Demoman), a acrobatic but well-armored silent girl (I think she was sleeping most of the time), and myself. We had set up camp in what appeared to be the top of a dam; there was a sweeping and smooth metallic surface going down into unknown depths on one side of us, and high walls with windows and outcrops on the other side. I climbed up to a shelf on the walled side of us, and then somehow turned into a morphball, specifically, the morphball created by Samus's Light Suit (Echoes). There I broke several glowing locks with standard morph bombs, and then fell out the other side to a door I had just opened. The door revealed an elevator shaped exactly like a big, red, hamster food pellet. I decided to scout ahead, so I went up.
The details on what I saw up there are hazy, but a guard spotted me, so I went down the elevator again. When I reached the giant empty room, however, it had somehow turned into an auditorium of sorts! Hundreds upon hundreds of people were sitting in chairs where the smooth inclined plane was, and all of them were sleeping. The heavy guy ran up to meet me, and I whispered something about a Centurion coming. He positioned himself on a peninsula-type catwalk that extended from the top of the "auditorium," and I hid myself in the shadows of the wall. Sure enough, some bulky guy in a military uniform came stomping right towards Mr. Broad Shoulders, and tried to grab for him. The big guy did likewise and with some difficulty, started rotating him over the edge of the catwalk. At this point I rushed forward and gave him a mighty kick-- which to my surprise, sent the guard flying past the sleeping people and over the edge of what used to be a dam, onto a hard floor below. I didn't want to imagine what that would do to a person, but I heard an unpleasant "SMACK!" People woke up to this noise, and started looking around in dead silence.
Details become hazy again, but my team snuck swiftly into a shipping and receiving cargo area to escape some mean looking robots. When the door closed behind us, a cutscene started in the previous room: the robots were debating which door we had taken. "Fools!" cried the largest one, "it must be the light cargo area!" One of its associates reasoned, however, that the light cargo door has a pressure pad requiring a weight of 400 kilograms to open it (I wasn't aware of this before the robot said it). "They have a gravity manipulation device, such things mean nothing to them! Get that into your head!" While yelling this, the largest robot had been drilling a hole in the head of the aforementioned associate. I suppose he was manually getting that into his head.
The end of the dream was brought about by yelling downstairs. The layout and appearance of the dam/auditorium stays crystal clear in my mind, however.
