Fungus Amongus.
There was no light. As I lay thrashing on the emergency room table after a car wreck, I was suddenly looking down at my body thrashing on the table from far above the ceiling. I turned and there was only gray that quickly turned to black. When my inner voice asked about someone that wouldn't be born until fifteen years later I went immediately back into my body.
That was almost forty years ago now.
I would imagine that gray is still there.
