1. “Entropic” means “undergoing entropy” — in other words, moving from a state of order to disorder. Here, I suspect that “both solid and entropic” means that some of the bodies are depicted as whole, intact, firm bodies, but others are depicted as if they were dissolving, fuzzy, vaporous, or otherwise unsolid.
2. I think “psychically charged scenarios” means settings that for some reason trigger an deep emotional response. “X-Charged” in this context means “heavy or laden with X content.” Example: “In emotionally-charged testimony, the victim described the attack that left her husband dead.”
