a sense of motion as the camera passes by walls. Whedon also used unusual framing for shots, often leaving much of the frame empty, with a character being placed near the bottom or off to the side. The scenes in Spike's crypt, part of Giles' dream, were shot in black-and-white to emphasize that Spike is seen as "an old 30s movie villain". The outdoor scene in which Xander sees Buffy in the sandbox was intentionally overexposed, intensifying the foreground and blowing out the background, making the sky look white; flash frames were also used in the shot of Buffy in the desert. Whedon allowed some shots to last far longer than is common in a television episode; this cinematic technique allowed the images to take on meaning. Highly stylized lighting is used throughout Xander's dream. In the university hallway the scene is lit with green and orange gels, while the almost shot-for-shot re-creation of the Apocalypse Now section is lit with carefully controlled spotlights which allow the background to fall out to black. Whedon cites The Limey as an inspiration for the unnaturally colored university sequence, and had the scene from Apocalypse Now playing on tape during filming to ensure as close a match as possible for that sequence. When Xander is driving the ice cream truck with Anya, the backgrounds outside the car intentionally look fake, to give a sense of stillness where there should be motion. Whedon originally wanted to use rear-screen projection for the driving scene, but had to utilize greenscreen instead, as rear-screen projection would be difficult to set up on their stages. Some special effects shots came about by accident; in his commentary Whedon explains that when Buffy smeared the mud all over her face, it looked as though she was giving herself a facial. He therefore dissolved the shot into a negative image, creating intense colors that made the shot more interesting. Dynamic editing contributed to the surrealistic nature of the episode. Abrupt cuts from close-up to extreme wide angles and sudden shifts from normal speed to super slow-motion are used in Buffy's dream: several sequences become slow-motion partway through them, then revert to normal speed as they continue. Xander's dream features mismatches between sound and image: characters are sometimes shown not speaking even as their voices are heard. Additionally, silence is used frequently, to both reflect the characters' disorientation and to unsettle the
