To dream of the pope symbolizes your spirituality, inspiration, moral values and religious beliefs.
On the other hand, it may mean being dogmatic, self-righteous, and maintaining a holier-than-thou attitude.
A dream of mass symbolizes a connection to a set of religious principles.
To dream of going to mass and feeling a great relief represents your need to desire solace in a church or a friend or family member.
Say if you have never attended a Catholic mass before except in your dream, your subconscious may be borrowing symbolism in order to construct a space in which to express spiritual curiosity.
