Entering the Cave
Scholars have said that whoever sees themselves entering a mountain cave might attain guidance in their religion and affairs, assume authority from the ruler, and gain power. If they enter a mountain cave within a larger cavern, they might scheme against a king or a powerful man. If a mountain confronts them, they might face worry or a journey, or a powerful man, or a difficult matter, or a harsh, stern woman.
