In our dreams we experience a variety of emotions. Crying in the dream state generally has the same meaning as crying in daily life. It is a release of negative emotion, frustration, or fear. On the other hand, you could be experiencing the tears of joy. Due to repression or denial, sometimes people are unable to express their feelings. In the dream state some of our defense mechanisms may relax and an emotional release occurs. Some emotional dreams may be compensatory in nature. Thus, if you never cry in daily life, you may cry in your dreams.
To dream that you are crying, signifies a release of negative emotions that is more likely caused by some waking situation rather than the events of the dream itself. Your dream is a way to regain some emotional balance and a way to safely let out your fears and frustrations. In our daily lives, we tend to ignore, deny, or repress our feelings. But in our dream state, our defense mechanisms are no longer on guard and thus allow for the release of such emotions.
To wake up crying, represents some suppressed hurt or previous trauma that is coming up to the surface. You can no longer suppress these emotions. They need to be dealt with head on.
To dream that no one hears or responds to your cries, represents your helplessness and difficulties and frustrations in trying to communicate with others. You feel that your words are falling on deaf ears. Perhaps your dream is telling you to be more vocal and work harder to get your point across.
