Eloquence
Scholars have said that if someone sees themselves as a non-Arab who then becomes eloquent in a dream, it may indicate honor, glory, and dominion, to the extent that they become unrivaled in their field. It is said that if they are a ruler, they attain a high status, and if they are a merchant, they become renowned in the world, and similarly in any profession they practice.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
