To dream of Christians represents aspects of your personality that are obsessed with never doing anything wrong. Self-awareness of always doing nothing wrong or being noticed doing nothing wrong.
Negatively, Christians in dreams may represent jealousy that you ever made a mistake or bad moral choice. Being afraid to do anything wrong, or to take a risk. People or situations that you feel go too far being wonderful or moral. Feeling that family is too much of a priority. It may also also reflect an arrogant attitude about thinking your positive choices are the only ones anyone should have. It may also be a sign that you are "kicking yourself" over mistake you made or having problems forgiving yourself.
