An access route or approach to a person, place, situation, etc.
Degree of accessibility (for example, dreaming that a driveway to a celebrity's house is very steep might represent how difficult it would be to meet that person)
The way you interact with people who approach you (since your house represents you)
Possible dream symbol meanings in the dream dictionary are suggested. No "standard meanings" exist because dream meaning is subjective and specific to the dreamer.
