Seeing an ibex in your dream may indicate the arrival of a foreigner in your city. If you catch an ibex, it suggests that you may receive financial gain from a wealthy or powerful person. This dream could symbolize the beginning of new opportunities in your life and a sign of economic improvement.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Ibex" (page 220) â resolved via the equivalent "Mountain goat" entry.
In a dream, a mountain goat represents a foreigner who will be passing by one's town. Catching a mountain goat in a dream means receiving money from a king or from a wealthy and a powerful person, for the mountain in a dream represents such a person and the goat represents the prize. Looking at a mountain goat in a dream means slandering a person who holds an important position in the government and who is well connected with the ruler. Catching a mountain goat in a dream means harm and sufferings, though eating its meat in a dream means that one will receive money from such a person. (Also see Oryx)
