Ants swarming in the kitchen

"I noticed it in a kitchen that mostly felt like mine, this dark patch moving near the baseboard, and when I looked closer it was ants, way more than should fit in that space, a solid shifting carpet of them spreading out from somewhere I couldn't trace. I stepped back fast. I tried to get to the door and they were already there too, line of them crossing right where I needed to walk, and more kept pouring in from under the cabinets, from cracks that weren't there a second ago. The floor practically disappeared under the moving mass of them. I felt them on my feet even though I hadn't stepped in anything, that crawling sensation up my ankles, and I kept shaking my legs even though nothing was actually there when I looked down. The counters had them too now, covering a plate of food that appeared out of nowhere. I tried to find any clear path and every direction had more of them, spreading faster than I could track. That crawling feeling just kept building everywhere, never let up, right until I woke up still brushing frantically at my legs in the dark."
