Postcard
An open piece of card sent through the post — a short message in plain view of everyone who handles it.
A postcard in a dream is the dream's image of a short message in plain view of everyone who handles it. The postcard does not pretend to be private; the few lines on the back are readable by the sorter, the carrier, anyone who picks it up at the other end. The dream brings the postcard when something in your life — a piece of news to a friend, a brief gesture of thinking of someone, a holiday-tone update — is being sent in a form that does not need to be secret. A postcard arriving at the right address is the dream affirming the easy public greeting. A postcard carrying a sentence too private for the open form, with the message now read by everyone in the chain, is the dream noting that the wrong medium was used for the content, and the privacy has been compromised by the cheapness of the carrier chosen.
