(Sling; Catapult) Bringing a slingshot before a sick person in a dream means transporting him to a new place, or it could mean his death and burial.
A slingshot in a dream also means removal of a guardian from his office, or recovering from drug addiction, or it may represent a messenger. Using a slingshot to cast stones at others in a dream also means rightly invoking a strong curse on them.
If one sees a woman using a slingshot to throw stones at him in a dream, it means sorcery or witchcraft.
A slingshot in a dream also denotes just and harsh words. Holding a slingshot and preparing to shoot in a dream represents oneâs strength and determination to say something just and true.
If one carries a slingshot but adoes not use it to cast stones in the dream, it means that he will repent for his sin.
