From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Lion" (page 255).
A lioness in a dream represents ignorance, pride, affectation and perfidy. Seeing a lion without being seen, means escape from harm one may fear, attaining knowledge and growing in wisdom. A struggle with a lion that does not lead to one's death in a dream means observing a long lasting diet caused by an illness. If one fights with a lion and eats or snatches off a piece of his flesh, bones or hair in a dream, it means that he will attain success,leadership, wealth or conquer his enemy. Sleeping beside a lion in a dream means safety from illness, or protection from one's enemy. If one sees a lion inside his own house in a dream, it means that he will gain the upper hand, or it could represent longevity and a high position in the world. A lion entering a town in a dream means a plague that will strike such a town. (Also see Lioness)
