Dreaming of facing an enemy signifies respect, the resolution of conflict, and the potential for mutual understanding. If you encounter an enemy in your dream, it may indicate the beginning of a new relationship. This dream serves as a reminder that despite opposition, if you are brave and confront the situation, you can emerge victorious. It may also bring the possibility of new friendships into your life.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Enemy" (page 142).
To meet an enemy in a dream signifies honor, signing a treaty, rising above differences, receiving God's help and victory. Facing one's enemy in a dream also means befriending him. If one is threatened by his enemy in a dream, it means that he will win the upper hand. Ifone is promised good things by his enemy in a dream, it means that he will fall into his trap and lose his fight to him. Ifone's enemy advises him in a dream, it means that he will betray him. If one sees an enemy invading a land in a dream, it means that a destructive flood will devastate that place. Ifone's enemy confides to him or pleases him in a dream, it means that he will suffer distress and adversities. Ifone is captured for a ransom by his enemy in a dream, it means that he indulges in sins and that he is a hostage of his own sins. (Also see Blessings; Enmity; Introduction p. xxui)
