Not to commit blasphemy against Holy Spirit,but I believe that this vision is fruitless (therefore not from God).
what does it profit a man if he gains the whole worold but loses his soul?
what does it profit a man,if he saaves the lives of thousand unborn children,but goes to hell himself?
in my country,some people are reported to repent of their sins (eg.impurity)after seeing a moslem Imam in a dream.some people even claim to have seen Mary or Jesus,and they become better moslems after these visions.
devil can bring a fake conversion.
good actions done in the state of mortal sin (schism)are purely natural and devoid of merit.
