This was back around 2012 or 2013, I was staying over at a friends house and had this dream. The first thing I did was tell my friend about my dream and I still remember it to this day.
The world was made up of different floating islands in the ocean, each island represented a specific culture from all time periods and places. I was living on "Viking Island" and was with two of my real life friends. We were in the center of the island when a pillar of bright blue water came down from the sky and a woman descended within it. She told us "You must all push Viking Island into San Francisco Island, and slay them all." Everyone looked at each other in confusion, one person said that the color of the pillar's water was too blue and doesn't match the ocean's blue, so it should not be trusted. But the general consensus was that we wanted to raid anyway, so we all jumped into the water and started pushing together. Not long after, the island crashes into San Francisco Island, and everyone storms it. Everyone on the island was an extremely stereotypical 2012-era hipster and emo type and they just tried to run away.
One of my friends and I stumbled into an old, dusty server room with a large monitor. As we walked in, it lit up and announced, "BRING ME BLUEPRINTS." But since my friend and I were from Viking Island, we didn't know what that meant, so we tried our best by bringing it various objects we found trying to figure out what it wanted. Things like trash we found in bins, squirrels, birds, items in the server room, but the monitor just kept replying, "THIS IS NOT A BLUEPRINT." Eventually we just got annoyed and left to go raid some more San Francisco homes.
