Echoed Feelings

The world consistes of many vast empty places that people like to visit. Almost all these places are empty but once had people or living things roaming it. Now they echo, like they're hollow. I don't know how to explain it, its like the living things just disappeared. We may not know what all roamed in these places but we do know that they left a mark, a mark of feelings. Weather that feeling was fear or excitement, we dont know, but we do know that those feelings echo threw us when we visit them.
