Emotions expressed in dreams are a way for you to act out the feelings that you normally would not express if you were awake. The dream provides a “safe” outlet for these emotions instead of letting them get pent up.
However if you feel of mix of emotions in your dream, especially if they are contradictory, then it means that your conscious and subconscious are in an emotional conflict.

According to some psychologists, we dream to relieve and stabilize our emotions.
Otherwise, we would ultimately explode. Sometimes when we dream, we feel very strong emotions impossible to experience in real life.
According to Jung, they come from the less developed part (the shadow) of our psyche.
Some superstitions recommend interpreting dreams by reversing the emotions provoked. If, for example, you dream that you are angry, it means that soon you will receive good news.
If you feel emotional in your dream, you may be experiencing a physical hormonal surge in your body. Or you may be repressing your actual feelings about something and they are sprouting up in your dream where you aren’t as likely to hold them down. Emotional feelings in dreams about water symbolize meaningful sexual feelings.
