Why do we feel the existence of life in the vortices of the ocean?
The boundary surface of the vortex in the ocean is ambiguous, and the existence of the vortex is maintained even if a person were to enter it.

Even if the components of an artwork are temporally and spatially separate, in other words moving freely or moved around by people, when a density and continuity or order are formed in the whole or in parts, it is perceived as a single entity, and even life-like. The physical position of the components become freed, and the surface boundary of the work's existence becomes ambiguous.

Water, bubbles, fog, and mist, which are free-moving components to begin with, are recognized as a single entity when density and continuity or order, or cognitive continuity and order, are formed in the whole or in parts. Since the components move freely, the boundary surface with our bodies becomes ambiguous.
