Dream - The drugstore outside the universe
In the dream, I kept going to a small drugstore. Over time, it gradually changed into a much larger store, though it was still a drugstore. Also, very few people had been in it at first, but the store gradually accumulated more and more people as time went on. It wasn't just that the store itself got larger, though that of course helped.
At some point, I became aware that time was running short and the store was about to close. I think that announcements were being made, perhaps over loudspeakers. There may have been 5 or 10 minutes left. Although I had been going to the store alone, this time someone was with me. Unable to locate this person, I eventually went out the back of the store, still searching.
I found that the store existed in another dimension, or perhaps another reality. The store was on a square that looked like something generated by a computer, including having a grainy texture. A similar square was to the side and connected to it. The second square did not have a building, but it had rough terrain and steep, tall hills. It, too, looked computer generated, with dirt and grass being represented for the most part by grainy colors. There was also something to the back of the original square (the one with the store), but I'm not sure now what it was. The squares themselves seemed to have no thickness, like a computer generated terrain that consisted only of the surface, with nothing underneath it.
A formless grayness lay outside the squares and associated structures, a grayness which seemed to be without end but also without an up or down and where things like measurements had no meaning. I did not know exactly what would happen if I fell off the square areas into the grayness, but it seemed to be something very bad, and that I would, in some way, be lost. I seemed at this point concerned both with finding the person I was with and eluding some people who were after me or who were trying to stop me.
Eventually, I got back inside the store and had somewhere located the person, and we were trying to leave. I noticed that there were still quite a few people in the store, and I started trying to warn them to leave, too. I knew that when the store closed that anyone in it would be trapped in that dimension. A lot of people left, and we had to leave ourselves now. Time was almost up and there was no more time left to do anything else but leave.
As we rushed toward the doors (there were several doors at the front), someone rushed to try to block the exit. In his haste, though, he hit the door frame and was leaning against it at an angle. We rushed past him and out the door.
Once outside, we saw a broad aisle leading to some more doors that led to our reality. On each side of the aisle, the square on which the store stood extended forward to the dimensional barrier, but the area outside the aisle was dimly lit. In the dimly lit area, scattered figures were seen, figures who wanted to stop us and trap us there. We rushed past them and through the door into our reality.
After running a short distance, I looked back and saw someone go through the door at the last split second, practically leaping through. He fell on the ground as he came through, unable to keep to his feet. It gave us a little extra time to get away from him, and we got in a car and apparently escaped.
