Nobody was sure how it was revealed, but outside of the building we were all residing in, the rest of the world had more or less fell into anarchy. Our building had limited resources, but there were a lot of people so certainly, there was the manpower to make things work as long as everyone did their part. Communication with the rest of the world no longer seemed possible, so we were all sort of off the grid.
There was another building not far from where the building this dream was taking place in, and I suggested with the people I was with, that perhaps we should send some people over there, and forage for supplies and gather anything that we could use in our new residence for an indeterminate amount of time. Many agreed with me, and we made tentative plans to make the trek over to the other building.
Before executing the plan to travel, someone brought to my attention that what if the other building were not completely empty as I had initially hypothesized it was? What if there were other people in that building, in the exact same predicament as we were in? I hadn’t considered such possibilities. The trip to the other building never happened.
