(See Also: Feelings)
Emotions in dreams are not symbolic; they are just themselves. However, you need to be aware that emotions come from the unconscious, from what Jung calls ‘the Shadow5 - the ‘inferior5, undeveloped functions of your psyche. They may therefore be very disturbing, and often you will not acknowledge them as your own: instead, you may project them on to someone else. Therefore you need to be open to the possibility - or even the probability - that other people (or animals) in dreams represent parts of yourself, and that any emotion that is driving them in the dream is driving you in real life. (For inferior functions, shadow and projection).
[1]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.
