Dream about someone else when in a relationship is an evidence for your inability to function in a certain situation of your life. Perhaps you feel that you are not getting through to others or that they are not understanding you. There is some aspect of yourself that you are also rejecting or refusing to acknowledge. It symbolises your hopes or your fears of how things will turn out. You are taking everything too personally.
Someone else when in a relationship dream is sadly a warning alert for issues of dependency and hopelessness. You are not taking life’s issues and problems seriously enough. You have been avoiding the problem for too long. It sadly draws attention to anger and aggression directed at you or someone else. No one should question your motives or choices.
If you dreamt about someone else when in a relationship:
There is such a thing as being too honest. You’ve experienced in the past how your determination to tell the whole truth and nothing but the truth can cause hurt feelings. Today try to exercise a bit of tact and diplomacy. You will still be able to get your point across, with the added bonus that your audience will still be speaking to you once you’ve done so.
