The Royal Court / Office
Scholars have said that seeing the Divan (office) in a dream may carry meanings related to death or survival from it, and sometimes it indicates a place of calamities, where its closure signifies their removal and its opening their occurrence. The dream may also denote gaining authority and governance for one who sees himself eating from the Sultan's Divan, or achieving sufficiency in livelihood and pleasant sustenance for one who registers his name there without hardship.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
