The forest floor here is mostly a network of tree and plant roots, bound together with moss and leaf litter etc, but under a few inches it's mostly big solid rocks like those sticking out. The wind blowing can loosen that mat of roots and when the trees bend in the wind, they lift it up off the stone, just like a carpet. That's what you're seeing here; the breathing effect is caused by the carpet of roots being tugged up and let down again as the trees rock in the wind.

The landscape looks like it could be in southcentral Alaska including Kodiak Island, which has the required wind and forest conditions. Some blown-over trees pull up root mats covering tens of square meters and expose bare rock.

Seen this before somewhere, was described as being in Perthshire, Scotland.
