In a dream, a lancet represents a slanderer. To cause a horizontal cut to someone with a lancet in a dream means backbiting him, slandering him and causing enmity between people. If the wound is vertical in the dream, then it means speaking well of someone and bringing people’s hearts together. (Alsosee Javelin | Lance)
