Dreaming of avoiding something or someone means you are choosing to leave a certain part of your life unfulfilled. Try remembering what it is that you are avoiding in your dream, and see how it connects to your waking life. Start by being present to deter the avoidance dreams in their tracks.
Choose to be confrontational rather than running away, it is the only way to grow as a person. Attend a party for five minutes instead of not going at all.
