Structures into which people once entered now become the skeletons of looming kudzu monsters; their odd shapes casting equally odd shadows beneath unflinching and unknowing light.
In the middle front, I think I see the fear monster from the Lost in Space episode "Space Creature." There is a very memorable line from that show where the creature announces his true identity: "I am your id!" From context and pronunciation it seems safe to assume he is referring to the Freudian term. And would it not be like an id, to lie obscured beneath a thick layer of seemingly innocuous, verdant foliage?
