Sealing
Closing something with a seal — the final act that makes what is inside no longer open to revision.
Sealing in a dream is the dream's image of the final act that makes what is inside no longer open to revision. The seal is not just closing; the seal is the committed close. The dream brings sealing when something in your life — a letter, an agreement, a decision, a tomb — has reached the moment when the open state is being deliberately ended and the contents are being committed to what they are. A seal pressed cleanly is the dream affirming the honest close. A seal broken open shortly after being made, the commitment immediately reopened, is the dream noting that the act of finishing was performed and the actual finish has not been allowed to hold.
