What are gray dreams about?

Last night I had a dream where I was in a stone fortress in the middle of the desert known to the people as "The Wastelands." The Wastelands air was poisoned and you could only breath it for a small amount of time before having to go back to the base for air. The Wastelands has uranium crystals incased in glass which the base need for power (though the base had no electricity.)To activate the crystals you needed to twist the top and the power immediately goes to the base, with no wires or anything. Another location in The Wastelands was know as "The Pits." The pits were random section covered in blueish grass that dipped down about 35 feet and had undrinkable water at the bottom. The pits went on for miles with no end to them in sight. Another type of power the base needed was down there two, in random pipes peeking out of the water or the side of a cliff leading to the pits. In the pipes were a weird gray gooey substance that needed to be carried back to the base and given to scientists to extract the power from it.

I was trapped in an industrial labyrinth with only a pistol. It was barely visible with the only ambient light coming from holes in the roof of the warehouse. I was chased by these disgustingly fat sausage shaped monsters frantically dragging and waddling themselves towards me with these frail and disproportionately small arms.

Their skin was a discolored gray with dozens of brown and green spots as if it were badly molding bread. The monsters’ skin stretched so tightly around their bodies that their rib cages bulged through despite their obese figure. The bottom portion of their faces were split open and dangled loosely like raw steak.

I tried shooting the monsters but that only seemed to make them angrier. Dropping the gun I ran, stumbling clumsily over stray pipes and occasionally my own feet. I cried, begged and screamed for help but my cries were drowned out by the cold darkness of the labyrinth and the guttural and bubbling growling coming from the wall of flesh nipping at my heals.

A burning vibration, what I believe to be dream pain, radiated throughout my foot into my calf as I collapsed to floor. I looked back to see half of my leg submerged in its gaping and fleshy maw, it’s cold and indifferent eyes locked with mine. I clawed at the grimy linoleum flooring as the monster dragged me deeper and deeper into its mouth.

I could feel my skin rip, the pop of ligaments being tore from bone and the crushing of said bone. I could feel my breath get lighter and and hear my screams grow fainter as it’s tongue crushed down on my rib cage. The shrinking of ambient light coming from the labyrinth being the last thing I saw as it’s mouth closed shut.

The darkness of its insides melted with an unknown ambient light and I found myself back at the beginning of the labyrinth again, eyes desperately trying to fix themselves to the darkness around me, the monsters directly in front of me.
This scenario looped more than 5 times with me dying every time until I finally woke up.

Can't really find any info online about the black smoke, but my guess is something related to the massive fires here in California. We lost our home last year in the fire, so thinking's it's some sort of release of responsibility or moving on, getting it out of my system? But the blood I'm not sure.

I was standing there, and it was difficult to pee for a sec, then this puff of dark gray and black smoke trickled out of my penis, and I look in the toilet and the urine is all black and has red patch which I thought was blood. Of course this seemed perfectly normal to my dream brain. I was concerned a bit, but kept it to myself even though I was peeing in a public restroom next to other people who felt familiar like friends.

Anyway. Thank you whoever can crack this code haha.

It was called a Rover OX-80. It was a tiny hatchback, maybe a little bigger than a smart car, and it had a very short hood. The front of the car was maybe a foot away from the base of the windshield. The grille looked like a truck's from the eighties, with square headlights, and the whole car was blue-gray.

I keep seeing a gray skinned toned female with black hair. It’s as if she’s basically still in black in white. She’s usually screaming or about to scream once we make eye contact. None of the other people in my dream notice this women. In my recent dream I asked the people in my dream about her and they turned into her. What is the meaning of this?
