The meaning of emotion in dream | Dream Interpretation
The expression or release of emotions are very typical and healthy in dreams. Often, because of the lack of inhibitions in the dream state, you might experience extremes that your ego does not allow you to explore in your waking state. Emotions release psychological pressure and allows you to awaken in the morning feeling refreshed, invigorated, with a clean clear slate.
