Illustrate ghostly, ethereal figures that seem to be trapped between dimensions

Illustrate ghostly, ethereal figures that seem to be trapped between dimensions, their forms flickering in and out of existence. The figures should have haunting, empty eyes and appear to be whispering or reaching out toward the viewer. The background could be a desolate, haunted landscape, with swirling mists and fragmented images that hint at past horrors. The atmosphere should evoke a sense of loss, despair, and the inescapable past.
