“Restless,” the fourth-season finale of Buffy The Vampire Slayer, features four dream sequences, in which each of the main characters is stalked, Freddy Krueger-style, by “the first slayer.” This device allows for a lot of surreal images and moments of weird comedy, as well as a hard-to-resist opportunity to have Anthony Stewart Head break into song. But there are also some striking, unsettling touches that have the indefinable power and strangeness of a real dream, such as the shot of Xander looking miserable in over-bright sunshine as he watches himself working out of a food cart—all the while insisting that he doesn’t feel as if his friends are leaving him behind—and the sudden cuts to a wide shot, with the sound dropping out, during the climactic fight.
