one-time-i-dreamt:

The world was covered in gigantic, continent-sized solar panels similar to a Dyson sphere, and there were giant pillars holding them up. On the inside of the panels, on the side you would see looking up, a false sky was projected to suit the time of day outside. The panels were so ancient that some were damaged, and you could see the stars through them like rends in the sky. My girlfriend and I slowly climbed up one of the pillars and sat on the edge of a broken panel, looking down at the earth and out at the other huge panels, seeing where they were connected and seeing other broken ones miles away. We just sat up there for hours until I woke up. It was nice.
