Describe Titus' dream in 'Nudging Again'?

Titus has nightmares about the world, where he sees riots in the street, with people covered in blood, and police officers firing into a crowd. He also watches as a group near a factory is exposed to gas and begins to choke and die. He sees black slime cover miles of land, and animals who have broken limbs. His final vision is of a boy being pistol whipped.
