The mountain That came Too close

"I was standing in some town that didn't quite match anywhere real, and the sky just started going orange, too fast, no warning sound yet, just that color spreading. noticed people around me still going about normal stuff, which somehow made the dread worse, like I was the only one seeing it coming. Then the ground rumbled, deep, and I turned and there was a mountain way closer than any mountain should be able to get to a town, smoke pouring off the top thick and black. I tried to tell people and my voice came out thin, nobody stopping what they were doing. I started moving away from it, legs heavy, that slow dream-running, streets stretching longer every time I checked over my shoulder. ash started falling, light at first, then thicker, settling on everything like snow that didn't belong. A glow built at the top of the mountain, growing fast, and I kept running with nowhere clearly safe to run to, breath tight in my chest. Right as something lit up the whole sky orange-red the dream cut, and I woke up with my heart pounding, checking the window for a sky that was just normal dark."
