Dreaming about tongue is analogous to experiencing deep sensations of pleasure. The human tongue derives a great deal of pleasure from taste, texture, and temperature. A perfect combination of these elements elicits new experiences for the person with the tongue dream.
Also you will continue to venture outside your comfort zone to experience new pleasures.
In a dream, the tongue may also signify something else. The tongue may represent a person who is speaking too much about other people. Or that you are holding back from saying or expresses a lack of personal confidence. For example, if someone is talking about themselves and can’t find the right words to say it could be because they have an underlying fear that they are not perfect or not good enough in some way.
Some people believe that a dream of one’s tongue falling out signals that there is something wrong with one’s mouth and teeth.
