The Pulpit
Scholars have said that if a person sees themselves on a pulpit speaking good words, and they are worthy, it indicates achieving high status and authority. If not worthy, they might become known for their righteousness. However, if they see themselves on the pulpit not speaking or speaking ill, it may suggest crucifixion, as the pulpit has been likened to a tree trunk.
