Small island
A small piece of land surrounded entirely by water — a self-contained place reachable only by crossing.
A small island in a dream is the dream's image of a self-contained place that can only be reached by crossing water. The island has its own rules, its own resources, and a definite edge; nothing arrives or leaves without being carried across. The dream brings the small island when something in your life — a private project, a relationship that exists outside the rest of your social life, a piece of interior territory — is currently a contained place with a clear boundary and a small population. A small island visited and left at the proper time is the dream affirming the right respect for the boundary. A small island treated as if it were the mainland, with the dreamer trying to live on it permanently without arranging for supply, is the dream noting that the small place was not built to sustain a full life, and the crossings back to the larger land are still required.
