Death and Being Carried on a Bier
Interpreters have said that if one sees themselves dead and carried on a bier on men's shoulders, they might gain power and authority. However, this could also indicate corruption in their religion, oppressing people, and dominance over them. Their religious rectitude is hoped for as long as they are not buried in the dream, and the number of their followers in authority will be proportionate to those who followed their funeral.
