"X" can have a number of meanings: An unknown factor, something that is forbidden, a signature, the number 10, or a special demarcation such as one might find on a map. As with all dream imagery, the X can have one or more meanings for each of us and can vary according to how it has been presented in the dream.
Dream symbols should never be taken only their own. A symbol in a dream is not a guaranteed one symbol fits the same interpretation for everyone. In all cases the dream symbol must be taken in the context of the dream. Consider what other symbols appear along with the symbol you are trying to evaluate and how that symbol made you feel. How do the other dream characters respond to the symbol? What happens after the appearance of the symbol?
On a test an "x" might be used to fill in the box for the correct answer or an "x" might denote that your answer was wrong. An "X" on a door might mean "Do Not Enter" or it could possibly mean Room #10. First impressions are not always correct and each symbol must be examined taking it within the scope of the bigger picture.
Sometimes an X is merely an X while other times it's the spot on the map where the hidden treasure has been buried. X could be a bad sign, but it can also mean something good. Or in some cases it might mean nothing or merely that something is missing. Don't take X at face value and make every attempt to make sure the X factor of the equation is solved before coming to a final conclusion about what a dream means.
What is the first thing that comes to your mind when you think of X? How are you at solving mathematical equations? Have you ever had a dream where an X appeared and if so in what context did you see the X?
