Adding to or Subtracting from the Adhan
Scholars have said that seeing additions, subtractions, or alterations to the words of the Adhan may indicate oppression of people proportional to the change. As for calling the Adhan in the street, if the dreamer is a good person, it might signify enjoining good and forbidding evil. If they are corrupt, it could point to them being punished.
