What are some flashbacks in chapter 8-9in hachet

Brian tries to get a few more hours of sleep, and has a dream about first his father and then his friend Terry. In the dream, his father is trying to tell him something, but no sound is coming out of his mouth. Then the dream changes to Terry, who is sitting beside a barbecue pit making a fire with charcoal, lighter fluid, and a match. This frustrates Brian; he knows he needs a fire, but cannot figure out how he would make one.
