Spiritual vandalism takes place when our basic beliefs are destroyed or trashed. Under these circumstances the dream content will have a sense of violence and violation.
Psychological / emotional perspective: Vandalism suggests a degree of mindless damage and a vandal is the perpetrator of such mindlessness. From an emotional perspective such a dream may manifest when there has not been a natural respect for our feelings.
Material aspects: When in waking life there are so many examples of wanton destruction, it is not surprising that such images become part of our dream content. When perhaps our professional integrity is called into question we may translate that as vandalism. That part of our being that has no respect for the norms and customs of society may be pictured in dreams as a vandal. You might like to consult the entries for damage and violence.
