Seeing yourself as a leper in a dream may indicate that you are about to receive an inheritance, money, or clothing without adornments. However, another aspect of this dream suggests it could be a warning about losing the fruits of your labor or them becoming useless. Therefore, dreaming of leprosy serves as a caution that in some cases, your efforts may go in vain.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Leprosy" (page 252).
To see oneself as a leper in a dream means that one may receive an inheritance, money, or a garment without ornaments. Leprosy in a dream also means
working in vain, or losing the benefits of one's deeds because of one's arrogance toward his Lord, and consequently, he will earn God's displeasure. It also means being innocent from false allegations, or being subject to people's slanders. If one's leprous condition spreads throughout his entire body in the dream, it means a lastingprosperity.lfone sees himself praying under leprous condition in a dream, it means possessing unlawful and forbidden earnings, or forgetting whatever one has memorized from the Qur'an.
