Thanks for the info about line breaks, I will follow suit!
In the dream I had, it was the year 10000 AD and the world had become
unlivable. Instead, all of humanity seemed to live in these bubble
cities at the bottom of the deepest parts of the ocean. But there were
also some kinds of cars that drove on the seafloor and a person waiting
at the gate of the city to let us in. We were riding in one of these
underwater taxi things and approaching the city. The guard looked like a
military guy. He had some kind of small apparatus in front of his mouth
that seemed to allow him to breathe underwater. We were all wearing them
in fact, so even though we were underwater we didn't have to wear diving
suits or anything. I'm not sure why the cities were in bubbles in that
case, but it might have had something to do with the other most
memorable part of the dream: the giant squids. In the distance, there
were HUGE squids. Like giant squids, but way larger than even the
largest of those... they were the size of jumbo jets at least.
Anyway, it was one of the most memorable dreams I ever had. I find it
frustrating because I know there were several other "glimpses" into the
future of different dates in that dream, but the only one I remember was
10000 AD, which was seemingly the final one.
