This dream began in a city landscape.  Although the buildings were very close together, and the city was supposed to be very large, it had a cozy, small-town feel to it, and there were not a lot of people.  Also, none of the buildings exceeded about five stories.

  This next part was surely influenced by the commercials for the movie, The Day After Tomorrow.  Some members of my family, myself, and a few other people were in the street, when a great wall of water begins rushing towards us.

  We still have about 30 seconds before it gets to us, so we have time to watch it overtake buildings in its path, but because of how high it is there's nothing we can do to prepare for it; like getting on the top of a building.  Also, that street dead-ends at a building, so we can't run away from it either.

  Normally, if you were in that situation, the water would hit you and send you crashing into the building.  However, physics were a little different in this dream, so, the greatest concern for people who were on the street was actually suddenly being about a hundred feet under water, and wondering if they would make it to the top before running out of breath.

  Right before the water hit, I had the great idea to face away from it and lean forward.  This, according to the dream's physics, let me use the flow of the water to propel myself, at an angle, upwards and forwards, without having to swim at all, and I came out of the water, landing right on the roof of the end building.

  I turned to see what other people would be making it up alive, since no one else had my idea, and they were forced to swim upwards.  Pretty much everyone that was outside of a building managed to survive, and everyone, in any of the buildings, died.

  After a few minutes, the water level had lowered enough so that the roofs of the three-story buildings were exposed.  From that point it was pretty much figured that people would be now living on the roofs of buildings instead of in their homes.  I'm not sure why, but for some reason, the insides of even the uncovered parts of building were just not an option.

  I went into survival mode and began assessing what we had available on what was now our rooftop, and what was up for grabs in the water, which belonged to whoever was the first to grab it.

  There were some things that looked similar to five feet tall macramé plant hangers, except they were made of rope.  There were about four of them, and I suggest we could disassemble one to use as a long rope in retrieving items from the water.  Up against the end building was a large mass of items that floated there just a few feet below the surface, though the mass was mainly enormous blankets.

  The plan would be to swim out with the rope, tie it to an object, and then just pull the object back.  It never happened, however, because the dream skipped ahead a few days, and the water level had lowered about halfway, and then it skipped ahead again, to a week after the flood.

  At this point, the water was gone, and the street was covered in a thick layer of mud, which behaved more like clay, because it was being used to build things and fill in cracks.  I was a little upset by how most of the people were spending their time, and the mud, to create things that were not serving any practical purpose.

  One thing that was made was a huge slide from the second story window of the end building.  Not a slide like in a play ground, though.  It looked more like a solid stone stairway, solid to the ground, from beginning to end, and even had a short "banister", of sorts.

  Down this slide were being sent colorful, cartoon-like letters made of the mud, but the letters were sort of "dancing" and up-right, on their way down.  I was reminded of a Dr. Seuss cartoon.

  I wanted to see who was sending them down, so I went into the building, passed a few corpses of people who were in the building when the flood came, and entered another room.  That room was cleaned and had people working in it, though they looked more like students.  I went through the room and up some stairs to a set of very small rooms.

  These few rooms were the base for an alien race in the beginnings of their plan to enslave all humans.  They were basically human looking, though their hair was always combed straight back (the males' was, anyway), and they wore a uniform.  All members of the alien race were very strong and tough; close to bulletproof tough, except for their scientists, who were practically no body at all, and mostly frizzy hair sticking out.  It was very cartoon-like.

  I somehow incapacitated one alien, and went on to a small room where a scientist was working.  I immediately throw him into the mouth of the machine that was somehow producing the letters, and though I was unable to see what would happen to the scientist, I heard him (what of him there was) being shredding, as like in a mulching machine, and being deposited down the slide.

  At that point, the aliens decided to step up their strategy and became aggressive.  The dreamed changed to a non-post-flood Earth where the aliens occupied every place, and the ones of us that were not used as slaves were allowed to continue their daily lives in whatever manner would actually keep things running smoothly.

  There were still a lot of things the aliens didn't know about, so people were allowed to keep the electrical plants running, and so forth.  Any other little customs and jobs were acceptable provided nothing hindered the aliens´ efforts.

  I was now part of a small group of rebels secretly working against the aliens.  The man in charge happened to be Michael Madsen, the actor.  Our current objective was to light up a window in the tower of a building.  It was a small tower, so we had to climb up a ladder attached to the wall.  But first we had to convince the alien, in charge of that area, that what we were doing was going to keep daily life running smoothly.

  About four of us were in the group, and we all climbed up the ladder, which was about four stories high, the leader discovered it was a small candle that had to be lit, and then he lit it.  Mission accomplished, it was time to go, and he just let go of the ladder and dropped the full four stories straight down into some icy water below.  I was surprised as I watched him go down, and after, I said, "Well, I'm not dong that." Then one of the other guys dropped down after.

  The dream changed again to some years later.  At this point, there were a number of aliens sympathetic to the humans, though none actually helped the humans.  There were some fights, which illustrated the toughness of the aliens.  They barely felt it if you punched them or hit them with guns (as with the butt or muzzle).

  I'm not sure exactly why I never thought to actually shoot one with the gun I was using.  Apart from that one scientist, who was the only one there ever seemed to be, there was no killing at all.

  There were some things that could harm them, and it turned out that they had since confiscated all human instruments that could do so.  At another point, I was sneaking around a large warehouse, next to an alien "military" base.  I snuck inside in order to find something to use against them.  I found a big pile of clothes on the floor: mostly blue jeans.

  The big door started lifting up, so I needed to hide somewhere.  I was forced to crawl under the pile of clothes.  The aliens were not looking for me, but they did need to pick out some things from the pile, and one aliens uncovered my face.  Fortunately, he was a sympathetic one, and did not say anything.  He covered my face, and when they all had left, I continued my search.

  I went out a back window that, while about three feet off the floor, was ground level on the outside.  It led to a strip of grass between the warehouse and a brick building.  I'm unclear on the exact layout, but the main room of the brick building was long, and it seemed to be a cafeteria.  Along side that was a shorter and thinner room which had a sort of pit in the floor.

  It was like a room specifically for a swimming pool, but the pool was filled with dirt, and there was a walking path all the way around it.  Along the other side of that room was another, larger room, which was of no consequence in the dream.

  I had some feeling that I would find something useful in the room with the dirt, but someone started to come in, so I worked myself into the dirt to hide.  At that point, I took some time to try some dream control, and allow myself to move through the dirt as if it were not there.  I was still unable to see through the dirt, which in itself defeated the purpose, but I also was too afraid of "drowning" in it.

  You see, in other dreams, while not exerting dream control, I had been able to breath under water, what with not actually being under water in real life.  I was hoping to use that same ability, but part of me was afraid I would lose control enough for my body to actually think I was submerged in dirt, as far as my breathing goes.

  The next little bit was a blur, but I was eventually out of the dirt, and I was digging to see what I could find.  Buried under the dirt were many barrels, and other containers, of lemon Gatorade, or at least a similar liquid.  A female alien walked in, and some apparent allies grabbed her.  I got a container of the liquid and splashed some on her.

  To the aliens, the liquid, which was a drink to humans, made them feel like they were receiving an intensely painful chemical burn, though the pain was short lived and caused no physical damage.

  I don't recall exactly what we were going to use her for, but she was to be instrumental in accomplishing something.  The dream skipped a little bit to me being in a large storage shed.  Some of what was in there could be used as a weapon, but I was not able to find anything.

  The dream was losing its integrity.  I thought, at one point, that it would be really good if I could find an ice pick to use.  Also, a hammer would have been effective.  Piercing weapons or anything that would allow a powerful and concentrated impact was an effective weapon.

  If there was more after that, I don't recall it.
