Wounding Without Blood
Scholars have said that if one dreams of someone wounding them without blood flowing, it might indicate that the one inflicting the wound speaks a truthful word about the dreamer as a response. If blood flows, it might signify that the inflictor slanders them with true accusations, and the wounded person is absolved of sin.
