I had a dream about trying to build an airport using the building blocks in Subnautica. Or maybe the airport was already built using some other construction technique, and I was trying to figure out how to build my own structure. In addition to the big prefab habitat modules like 'large room', you could make things out of these long hollow capsule-shaped things, maybe a foot in diameter and 8 feet long. I had gotten together enough materials to build a closet out of them, but it seemed like an awkward way to build stuff. Why not just let us build with cubes, like Minecraft, I wondered.

There was a part where I was swimming around in some dark cave and then it started edging into a lucid dream. Usually when this happens I just wake up shortly afterwards, which as soon as it started happening I kind of regretted, because I knew I needed more sleep.
