I've had something almost like what you describe. I only had it once though, when I had a real bad fever. Reeeal bad. At the very least, 104. Maybe 7 or 8. Literally hallucinating, seeing people/things behind places they physically couldn't be. Horrible fucking time.
Ok. Dream time.>I'm up on a hill overlooking this little town>Well put together stick huts with grass roofs, you know how it looks, all over the place>Dirt roads, horse n cart, markets, dirty people, just an old town>Giant earthquake, the whole towns shaking and everybody is screaming. >They know.>This lower, rumbling screaming starts. Like a jet coming in.> My view point turns 3rd person at this point and zooms out to an overhead view of the whole town>The roads make it look almost like your pic, but more circular, no sharp corners>And right in the fucking center, is this giant rock, monolith type thing. With a face.>My view point starts to zoom into the center, to get a better look of this horror show.>And he is fucking SCREAMING.>AHHHHHHHHHHHHHHHHHHHHHHHHHHH>Just a giant rock, with eyes and a mouth. Human eyes, and human mouth.>I can feel my heart beating out of my chest, and I'm not even back at myself yet. This rock is just screaming.>He lurches forward, and starts to roll. Screaming the whole time.>Rolling around the whole fucking town. Like that goron at death mountain. In Zelda.> I know he's coming for me. I just know it.> Just start running for my life. I don't know where to go, but I need to.>His rolling is causing the earthquake to get worse and worse.>Still screaming>The houses around me are collapsing
That's about it.
It's been 23 years since I've had that dream, but it's still one of the most vivid ones I've ever had. I'll never forget the horror I felt in that place. That fucking face rock monster. Kind of like that annoying orange thing, or jenks(?), that keeps popping up around here, in the face, and, just a giant rock. Like, a potatoe, just, 50ft.
