If you were doing the nagging, you were using the dream as a subconscious safety valve which indicates that you are swallowing a big dose of resentment; better let off the steam to the person involved, or better yet, talk it over with a trusted friend first.
If you dreamed of being nagged, it’s a warning to be very cautious in whom (and also about what) you confide.
[1]To dream of being Nagged signifies that you will be the recipient of pleasing information. Be careful in whom you confide it.
[2]One may expect trials resulting from misunderstandings with relatives if he or she dreams of being nagged.
