Briefing dream of an increased probability of being cheated. The fair sex after such a dream to take a closer look at her lover because he is most likely withholding something from it.

I dreamed that you were the initiator and organizer of the briefing - this can be considered as a warning. You are too honest with people who clearly are not worthy of your sincerity.
