Letter
Psychological (Freud)
Depth psychology treats the letter as a message from the unconscious to the waking ego, an encrypted content that seeks to be recognized. An unopened or illegible letter points to a repressed truth or a feeling not yet admitted, waiting in concealment.
Oriental reading
In Oriental and Islamic interpretation the letter heralds news, a promise or incoming tidings, gladdening or admonishing according to its contents. A sealed letter points to a secret entrusted or an obligation drawing near, while a joyful letter signals good news and reunion.
Objects
Dream interpretation is for self-reflection and entertainment — it is not a medical or psychological diagnosis.
