A Hesitation in the World: Genre Undetermined

The flicker of wind made the leaves rustle against each other, and it was in the slight gap between the time of the rustling that gave her reason to realize that she was not at home after all, not sitting in her backyard and watching the autumn come into full season. It was a hesitation in the sounds around her that she noticed now, strong and not merely in the leaves. She lifted a handful of sand from her garden walk and let it run through her fingers, listening to the hiss as it struck the ground. The hiss lasted longer than it should have. She straightened, smoothing down her skirt as she rose.

Inspiration: The wind in the leaves outside my window.
Story Potential: High? At least medium-high. It's only a skeleton, but I like the shape of its bones.
Notes: Could easily go multiple ways. Science fiction--and she's in VR. Fantasy--and she's in fairyland/the underworld. Mainstream--Alzheimer's or just garden-variety mental illness (as if there is such a thing).
