Flirting in a dream can signify that the person is attracted to someone they know. It can also represent the person’s fantasies. Perhaps they want to be more confident or more attractive. Flirting in a dream may also mean that you are fantasizing about something, or it could be a sign of anxiety.
If you are flirting with someone in your dream this may symbolize that you’re attracted to them and feel comfortable around them. You may be attracted to them because of something like their physical appearance, how they act, how they speak, what they do for work, or what we do for fun together.
The other way is to see the flirting as an abstract representation of your thoughts about sexuality and relationships in general, both real-life and imagined scenarios where you’re involved with another person.
Lastly, it could be seen as a sign of any anxiety you might have such as worrying about making mistakes when interacting with people in real life or just feeling anxious about being near the person you are attracted to.
