The Tongue dream meaning is explained below using 1 different source. Each interpretation is shown with its source.
Interpretation 1 — Ibn Seerin
It symbolises his spokesperson and messenger. At other times it symbolises the soundness of his argument. Thus, if he sees his tongue as cut or short, it suggest that his argument regarding a certain dispute is weak. And if there is no such dispute, it symbolises his steadfastness on Deen. As opposed to the above, if he sees his tongue as elongated, it suggest that his argument is sound enough to make him gain victory over his opposition. And if there is no such dispute, it alludes to his habit of indulging in idle talk as well as his shamelessness..
A woman tongue seen as shortened or cut is always regarded as favourable.
