Level crossing
Where a road crosses a railway at grade — the place your route must yield to a route that does not stop.
A level crossing in a dream is the dream's image of a point where your own ordinary movement is interrupted by a heavier movement that has the right of way. The train will pass; the car waits. The dream brings the crossing when something in your life — a personal decision, a small daily plan — has come up against a larger process that arrives on its own schedule and must be allowed through. A level crossing waited at with the barriers down is the dream affirming the correct yielding. A level crossing chanced with the lights flashing is the dream noting that you decided your urgency outweighed a force that does not, in fact, brake for you.
