Seeing a hyena in your dream indicates that there is a cruel and treacherous adversary around you. The actions of this enemy may be guided by a malicious and ugly old woman or sorceress. If you dream of eating hyena meat, it signals that you might face danger or that your enemies are trying to harm you. This dream advises you to remain vigilant.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Hyena" (page 219).
A hyena in a dream represents a fierce, an unjust and a perfidious enemy whose actions stem from the directives of an evil and an ugly old witch. If one sees himself eating the meat of a hyena in a dream, it means that he is bewitched and does not know it, though subconsciously, he will desire and seek to be free from such an evil spell. Riding a hyena in a dream means marriage. A lame hyena in a dream represents a witch, or the wife of an unknown person, a jobless person, a loafer, or a cheater. Riding a hyena in a dream also means gaining authority. A hyena in a dream also may denote exposing one's secrets, interfering in people's business, effeminacy, a her maphroditic person, a wretched wife, or an ugly, treacherous and a disloyal woman. Thus, when interpreted to means a woman, it means that one may marry such a woman. Shooting a hyena with an arrow in a dream means corresponding with such a woman. Throwing a stone or a walnut at a hyena in a dream means slandering a woman. Hitting a hyena with a sword in a dream means lashing at such a woman with bad words.
