The room seemed cold, as though an invisible fog had swirled in through the window.

The fog swirled to a movement of air from the heights.

The fog lay upon the river and swirled over the bridge.

The fog swirled under the car wheels as though trying to escape into the ground.

The fog swirled too thickly to be sure of numbers.

The fog hovered and swirled above them, though there was no wind.

The fog swirled in banners past his eyes, making him blind.
