To nag almost always has a negative connotation, but when a spiritual idea or feeling keeps coming back and nagging at us we would be very wise to pay attention.
Psychological / emotional perspective: In dreams, if we are being nagged or scolded we will have recognized that we are not heeding our own inner truth.
Material aspects: From a mundane viewpoint, if we are nagging someone else in dreams we may actually be trying to justify our own actions. There may be a play on words here in that a nag is also an old horse, often one that does not deviate from a particular routine.
In old-fashioned parlance a nag was a scold or cantankerous old woman.
If in waking life we are used to negative reinforcement, nagging may have this relevance in both men’s and women’s dreams.
To dream of an old horse or a ‘nag’ indicates a winding down of an idea or project and suggests humility and acceptance at this time.
A nag trying to keep up with other horses in a dream implies an inability to let go of a project but cautions you to release any expectations for your own happiness.
To dream of a person nagging you suggests that you may be trying to ignore that little voice inside that is trying to steer you in the appropriate direction. There is a reminder to stop and listen as you have the answer and you deserve to be heard.
To dream of nagging another person may indicate a personal frustration with an unconscious hint to relax and step away from a current bothersome situation.
1. Good news and events in the ofﬁng.
2. Some conﬁdants are not trustworthy.
3. Feelings of repressed anger and resentment, usually regarding a relationship.
To dream that you ride on a white, gray, or dappled nag, signifies prosperity.
