Schreiben
Etwas Beständiges machen — einen inneren Satz in die sichtbare Aufzeichnung übertragen.
Writing in a dream is the dictionary's image of making something durable. A letter, a list, a book — the act of writing in the dream is the dream's image of an inner sentence that you have begun to commit to.
Writing something you cannot read on waking is the dream noting that the sentence is not yet ready, but is forming.
Where you often see it. Writing a letter you cannot finish. Writing a name you cannot remember. The dream uses writing for making something durable — moving an inner sentence into the visible record.
What it is not. Writing is not always literal. The dictionary reads it as the dreamer's choice to commit something to a form that outlasts the moment.
Related in the dictionary. Read writing with book, letter, hands, and any scene where the dreamer was making a record.
