Lucid Time!

The dream was set like some type of video game. It combined elements of survival and building games, things that wouldn't look out of place in games like Minecraft of Space Engineers. I was building an underground city focused around mining and doing an incredibly good job. The planet I was mining seemed to offer a near endless wealth of mineral resources and my city was expanding at a rapid pace.

At some point we dug into something and I became scared. I ordered an evacuation of the city, and ordered the last of my engineers to build a wall that sealed the city off from the outside world.

I at some point in the future returned. I was no longer in a commanding position, but rather just myself, leading a small party of characters to investigate my lost city and see if anything was salvageable. We came across the wall, but I had intentionally incorporated a weak point that you only needed to remove a few components in order to get back inside. I opened the wall and we entered into an overlook space that I had built very early in the city's construction. A small portion of the roof had collapsed and sunlight and water poured into the cavernous city below. Vines and plantlife grew freely over the huge industrial processing center, and numerous buildings jutted from the side of the cavern which had began to crumble.

We explored for some time when we came across workers being held hostage by some creatures. I felt bad that they had been left behind in my hasty retreat from the city and they said that there were others; and that we needed to fight back and get everyone out of here. It was their belief that my choice to abandon the city was a cowardly one; we could have won. But now that the mining city had decayed and the workers had been trapped for so long, they were ready to abandon it, but getting out meant we had to fight the thing that I was afraid of.

The workers found spaceships which we could use to fly through the mining tunnels to escape; the mining tunnels were really that large. The front of the ships was a long vertical rectangular prism with a rounded front, and the back was an array of four large engines on pods. Everyone began boarding the ships and found weapons with which to fight the creatures. Because of the distinctive shape of the front of these ships, I began internally calling them 'thumb drive ships', cause they reminded me in shape of a flash drive.

Something moaned deep within the cave and I remembered why I had been scared of it. A huge pale white human face started advancing down the mining tunnel. It opened its mouth and teeth came out which detached and became attack craft. The ships we were flying launched our own fighters, which I remember being distinctly plus-shaped with four wings going off in all directions around a central cupola module.

Things quickly devolved into an absolutely vicious battle. I became lucid and realized that the face was nothing to be afraid of. I ran out onto the top of one of the thumb drive ships and took off on fire jets, weaving my way about the dogfights and flinging fireballs at the enemy 'tooth' spaceships. I then turned to the huge face which was now advancing on the city and it smiled creepily. I decided I would attack it in the eye and flew straight towards it getting ready to punch. I flew right into the pupil, never hitting anything and everything went black. I became aware that I was now in a black void and I was losing the dream. I woke up.
