So here it is.....(from www.dreamsleep.net)
Psychological Meaning: A tongue may represent the things you say. You may need to express yourself or may have already said too much. Perhaps you’ve been saying something ‘tongue in cheek’? As the tongue plays a part in the sexual act, your dream may be saying something about this area of your life.
Mystical Meaning: If you dream of your own tongue, you will tell lies. If you see another person’s tongue, they will lie about you. An infected tongue means careless talk.
the bottom line is it's just a DREAM! hahhahah
