Why was the entrance covered up? What are they hiding? Is it a porthole to another world? Maybe there's a secret code or trigger that opens up an unseen door. . . ..
Or maybe this image is a metaphor for something in your life. I've got to admit, right now I feel like those stairs leading to a brick wall represents my writing efforts. (not to mention other areas in my life.)
What about you? What thoughts or stories are brought to mind by this picture? I'm curious.
