I've been here before in my dreams...

I used to have this weird recurring dream where it would start off pretty mundane and vividly in real life. I'd wake up and hop out of bed or fall down the stairs and as I hit the floor I just went through it falling through layers of earth and rock until eventually landing in this fucking hallway. I would hear weird noises coming from the darkness, be able to look up and down the hall once or twice and then wake up.

I had this same dream so many times that it has been burned into my memory and still gives me the chills.
