X
X - If you see an X in your dream, it is possible you may be lacking something in your life that you desire. An X is often used as a symbol for "wrong" or "missing." Look at how the X was used, and try to interpret what might be missing or incorrect in your waking periods.
X-Ray - If you dream of an X-ray, you may be feeling someone is "looking through you" and accessing very personal things that you do not wish to share. Dreaming of an x-ray may also indicate you are not feeling comfortable with your current state of health.
Xylophone - Imagine a xylophone in your head. Notice how many keys it has. If you dream of playing the xylophone incorrectly, you are probably feeling out of control in your life, in a situation, work or relationship. Is there something in your life that does not have "all the pieces?" Oppositely, playing a xylophone correctly shows you are able to manage many things to "play in harmony." If you hear a xylophone, think of how it was played. If you hear a fast song that makes you feel anything negative, you may have someone in your waking life pounding something into you, or perhaps you have something causing you stress. If you enjoy the tune, then you are in harmony with the many facets of your life.
