A leper is one who is dealing with leprosy. IT could also represent one who is rejected or an outcast.
Positive: Dreaming of a leper could be a representation of God wanting you to address a sickness or disease for the healing ministry. It could also symbolize God cursing your enemies like He did for Abraham. It could also represent being hand-picked by God amongst many.
Negative: To dream of a leper could indicate judgment in one’s life. It could also mean a characteristic of your heart is blocking you from succeeding. A leper could represent having an unclean spirit.
(Matthew 8:2; Matthew 10:8; Leviticus 14:3).
