Arguments
To dream of having an argument represents an inner conflict or an unresolved issue. Debating an issue or unsettled matter in your head. You may be doing something you don't believe in. Feeling that a situation isn't perfect enough. You may have a problem expressing your true feelings.
Alternatively, arguing may reflect a waking disagreement you are experiencing with someone else. Alternative opinions to your own may have been offered. Not liking someone else's ideas.
Consider who you are arguing with or what the subject of the argument is for additional meaning. How does it mirror your waking life?
