Groom
A man on his wedding day — a person publicly stating that he has chosen a partner.
A groom in a dream is the dream's image of a person publicly stating that he has chosen a specific partner and is willing to stand in front of a community to say so. The groom is not the marriage either; the groom is the particular act of standing up to be witnessed. The dream brings the groom when something in your life — a public commitment, a stated loyalty, a chosen alignment — is requiring you to stand visibly with what you have chosen rather than just to think of it privately. A groom present and waiting at the time agreed is the dream affirming the honest public commitment. A groom not arriving at the appointed hour is the dream noting that the public commitment, when the moment came, was not made, and the room is going to draw conclusions from the absence.
