When driving, fog is an obstacle or a hindrance that makes things obscure. In a dream it may represent those things that are creating confusion and prevent the dreamer from seeing clearly. The setting of the dream may also give you clues about the area of life that it is referring to. Is the fog over water or land, are you in familiar or unfamiliar surroundings? Does the dream represent the journey into the unconscious, where things are obscure and mysterious, or does it symbolize a part of daily life that is unclear, ambivalent and challenging. Either way, if the fog lifts before the dream ends, it suggests that awareness and clarity are forthcoming. However, if the fog in the dream was oppressive and frightening, take some time to reflect on what causes such feelings in daily life.
