The Groom
Scholars mention that if one dreams of being a "groom" without seeing or knowing the bride, it might signify his death or killing someone. However, if a man sees, knows, or has the bride named for him, it is interpreted as marriage and indicates gaining authority commensurate with the woman's status. Divorcing one's wife may signify being removed from authority.
