Identify explicitly what happened in Tish's dream/nightmare.

In Part II, Trish has a terrible nightmare where the emotional climax of the novel is heightened further. She wakes screaming from a dream about Fonny being in mortal danger: "In one of these dreams, Fonny was driving a truck, a great big truck, very fast, too fast, down the highway, and he was looking for me . . . There were two turnings off this highway, and they both looked exactly alike. The highway was on a cliff, above the sea. One of the turnings led to the driveway of our house; the other led to the cliff's edge and a drop straight down into the sea" (111).
