The Moon represents your fears and illusions and often comes out when you are projecting fear into your present and your future, based on your past experiences. You may have a painful memory that caused emotional distress, and rather than dealing with the emotions you pushed them down deep into your subconscious. Now, these emotions are making a reappearance, and you may find yourself under their influence on a conscious or subconscious level.
The Moon can indicate a time of uncertainty and illusion, when nothing is what it seems. Be careful of making fast decisions when The Moon appears because you may later realize you only had half the information you needed. You need to listen to and trust your intuition so you can see beyond what is in front of you.
