Source: Tafsir al-Ahlam al-Kabir (Ibn Sirin)
Dust in a dream is wealth. If it is on the face, it is worry, travel, and fatigue. Whoever sees dust rising to the sky, it is a matter that is lost and no news is known of it.

Dust indicates travel or confusion in a matter. Shaking it off clothes indicates poverty and loss of wealth. Dust on riding animals indicates wealth and spoils.

Dust is interpreted as wealth. Its rising to the sky indicates a great event happening in that region. Dust on clothes indicates a journey that brings wealth.
