The Moon represents uncertainty in the Tarot — something that is unclear, or obscured from you.
In this, the present position of a reading, it may mean that you are misunderstanding something or someone around you. You aren’t completely ignorant (like The Fool), you simply lack clarity. You may be afraid of what you don’t know. But the unknown will remain intimidating until you discover more about it, so you need to find out.
