Sidewalks define the path in most neighborhoods. In dreams, the sidewalk often feels more like the yellow-brick road in The Wizard of Oz, intended to help you stay on course. The sidewalk is interesting because it often leads to scenes that would not be found in a neighborhood. Instead, the sidewalk leads to mountains, caves, volcanoes, etc. It often leads the dreamer to the next place in order to move the dream story forward. As nonsensical as this sort of appearance of a sidewalk may seem, it is merely a method that your unconscious mind uses to further the dream story (such as the use of a well-known object or person as a bridge between story elements).
It is important to recognize that dreaming about a sidewalk as a significant symbol of the dream interpretation is rare. More often, the sidewalk is simply part of a common street scene.
Does the sidewalk take you to a place that sidewalks usually don't go?
Is the sidewalk or the street that you are walking along a familiar one or is it just an archetype of a sidewalk?
