To dream of the Vatican represents a perspective on a situation where you feel you have to tell people what to do. Dictating core values to others. Preoccupation with being an authority, giving orders, or lecturing others. Feeling that telling others what to is all that matters. A sign that you may be too controlling.
Alternatively, the Vatican may reflect your feelings about people whose advice or suggestions are too important to ignore. A sign that you are not thinking for yourself or too afraid to act alone.
