Border crossing
A monitored line between two countries — a deliberate place of inspection between one jurisdiction and the next.
A border crossing in a dream is the dream's image of a deliberate place of inspection between one jurisdiction and the next. The border does not stop traffic by default; it stops to look. The dream brings the border crossing when something in your life — a change of role, a move between communities, a transition between legal or social categories — is being inspected at the moment of the change. A border crossed honestly with the documents in order is the dream affirming the legitimate passage. A border crossed with concealed papers, or with the wrong papers, is the dream noting that the transition is being attempted on false ground, and the inspection is going to find what was meant to be hidden.
