"Seriously brain, what the hell?" A Thread For Weird Dreams and Nightmares

Well. I uh, was dreaming about getting to this place that looked like a weird mall at the end of the world by crawling through layers of tunnels, each styled like some horror game. One was a meat tunnel where goblins lived, another was super dusty and dry, one I'm sure was alive cause I kept hearing a really loud heartbeat. I was with other people but I don't remember who they were. Someone kept pushing me to go back, though, but I was pretty done with that meat tunnel.

Seriously. What the hell lead me to that outcome?
