Draeger's Dream Journal and Documentation

Subnautica-like dream
I am in some sort of very dark abandoned hospital, nearly everything made out of stainless steel, even floor and walls, with no sign of decoration or anything else that would make one feel in any way happy, or even at all positive. There's blood everywhere, and it's too silent. I walk through it, and I think I discover another person.

Next thing I remember is looking for something outside in the water in a small submarine, like the seamoth, in some sort of kelp biome reminiscent of Subnautica, but different. I get whatever it was that I was looking for and go back to some sort of base, which you enter by going under a sort of large hydraulic opening which opens as you approach it, and you go through to the surface of the water, and it closes again, and you are inside and can swim a few meters to dry land. There were other people, and we were working on something.

Then, the next thing we do is go to some exceedingly exceedingly large cave, in which a creature just a bit smaller lives. It's literally many many kilometers large and we do some sort of research mission. Then I wake up.

During the entire dream I felt really curious and excited, and in the hospital part very disturbed, hence the title.

Subnautica dream
I am at the Lost River in the cyclops submarine, located at an entrance to it which is just a large hole in the seabed. I am walking around the upper part of the ship while large so-called "ghost leviathans" attacking me. The cyclops seems to be invincible, yet the ghost leviathans are still able to push it around. One glitches through the ship hull and throws me back a bit. I remember being at a different location, likely the safe shallows, for a bit, before suddenly being back at the Lost River. I then drive the Cyclops through the hole into the Lost River.
