Swimming Hole

This section of the novel is disturbing to me. Chris is sleeping and clearly dreaming. She sees a group of guys standing around the water looking like they're about to go swimming. Then all you she sees is one of them naked and their penis starts to curl. "Naked. Huh. Kind of like a corkscrew...or a pig's t tail..a snake." Chris looks down and realizes she is naked as well, about to walk into the water. Before she goes in she steps on a large piece of glass. She sits down and pulls out the piece of glass that's stuck in her foot and with it she pulls out a rolled up piece of paper...like a scroll. On it was a drawing of a snake swimming with a group of dark figures. They're all swimming in filth, floating garbage, french fries, old burgers..and they're eating it while they swim. Keith is in the water with her and offers to give her something to eat... something that looks like a large bug, she refuses to take it because she is being pulled under by what looks like a snake. The snake ends up being Keith himself. Then she sits up from her bed and pulls the skin right off her back and throws it out of the tent she's in and into the woods...I believe that when she supposedly wakes up, she is still in her disturbing dream. The dream might not even be a dream at all, it's a premonition.
