To see your own tongue in your dream represents the things you say and express. You may have either said too much or you may need to express yourself more. If you dream that your tongue is unusually long, then it suggests that you are not being truthful and are lying to yourself about something. If your tongue is sore or looks unusual, then it indicates that you are talking negatively about somebody. The dream may also be a metaphor that you are tongue-tied. You are nervous about verbalizing or communicating some feeling or thought.
To dream that your tongue is hairy or that there is hair on your tongue indicates that you are regretting what you said. Something you said could be leaving a strange taste in your mouth.
To dream that you rip someone else’s tongue out indicates that you are extremely upset with something that this person has said, but you are not able to appropriately express your anger. Because you tend to keep your emotions inside, it is finding expression in your dreams in a violent way.
To dream that someone is sticking out their tongue at you refers to some sexual connotation. The tongue is sometimes connected with sexuality and maybe seen as a phallic symbol. Alternatively, the dream symbolises some sort of insult.
