Lying on One's Back
Interpreters mention that seeing a person lying on their back may indicate strength in their affairs, prosperity in their state, and control over worldly matters, as the earth is considered a strong support. However, if one lies on their back with an open mouth from which loaves of bread emerge, it might signify a decrease in their management, the decline of their authority, and others benefiting from their affairs.
Per Ibn Sirin's Muntakhab al-Kalam fi Tafsir al-Ahlam
