Dreaming about a couple means romantic affection, security in simple pleasures, deep attachments to persons and a desire for marriage and parenthood. Focus on the object of your affections in the waking hours.
Also, dreaming about couples may indicate that you are about to engage in a long-term relationship. You have committed most of your time and energy to this new relationship, leaving little time for anyone else and are thinking only of him/her when away from the person.
