In a dream, he is tired to see that he was excommunicated by a priest in a church. To be excommunicated in a dream is no. Seeing that the dream is excommunicated indicates that the person is strong in his religion and that Allahu Teala has obtained his consent.
In a dream, if one excommunicates someone else, he or she proves to the public that he makes suggestions and narratives about religion. Seeing that you excommunicate someone else in the dream signifies that the environment will be informed about religion.
