I have had the same memory/sometimes a dream about being in a cold damn dark place beneath the ground.
I am not trolling you or making it up either.
Ever since I was a kid, I had this memory of being in a place where it is very dark, almost no light, but there is large pipes or ducts down the walls, it's not too cold but not warm either, I can hear liquids dripping, people talking sometimes, and I can never find my way out of it.
I roam around this massive cavern/tunnel complex but can never find anyone.
Then I usually wake up in terror. This is literally the only dream that I have for the last 35 years.
Same dream every time. I know it means something, but what?
