Dreams dictionary: Miller Dream Interpretation
To dream you have a rival, is a sign that you will be slow in asserting your rights, and will lose favor with people of prominence. For a young woman, this dream is a warning to cherish the love she already holds, as she might unfortunately make a mistake in seeking other bonds. If you find that a rival has outwitted you, it signifies that you will be negligent in your business, and that you love personal ease to your detriment. If you imagine that you are the successful rival, it is good for your advancement, and you will find congeniality in your choice of a companion.
