Post office
The civic point where letters and parcels are sent — the public node through which messages and goods cross distance.
A post office in a dream is the dream's image of the public node through which messages and goods cross distance. The post office is not where the message is written; it is where the message is committed to the system of crossing. The dream brings the post office when something in your life — a letter, a gift, a piece of news being sent across a distance — is at the moment of being handed over to a system other than yourself. A post office where the package is successfully posted is the dream affirming the handover. A post office closed for the day, with the package still in your hand, is the dream noting that the moment of crossing the message was prepared for has been missed, and the delay was self-imposed by waiting too long.
