Thick, swirling mist with faint beams of moonlight cutting through it

Thick, swirling mist with faint beams of moonlight cutting through it. The mist moves slowly and fluidly, creating a sense of otherworldly calm and unease. Light and shadow play across the mist, with occasional glimpses of dark shapes or figures hidden within. The colors are primarily soft greys and pale blues, with subtle highlights from the moonlight. The effect should be both beautiful and haunting, adding depth and texture to any scene it is applied to. Art style: photorealistic, with attention to the natural movement of fog and light.
