It was like I was watching everything through a dark fog.

Now, as the figure moved closer, the swirling dark fog seemed to lift.

But uncertainty was closing in, like dark fog at dusk.

"Sokogiri" is a very dark fog, where you can't see anything for miles.

He followed after her before she could disappear into the dark fog.

Her mind's all dark and swirling fog, hard to see, but she's crying.

A dark fog seemed to be gathering beneath her kitchen cupboards.

There didn't seem to be anything at all, except dark fog far below, under my window.

He saw the woman, a white water nymph now, her hair like dark fog.

It was like looking at someone in a heavy, dark fog.
