The Sultan
Some interpreters mention that if a sultan, prince, or ruler sees what was previously mentioned (such as building in the air), it might indicate their removal from office or the loss of their authority, whether by death or a change in their life.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
