Not in their dreams, or during trances, but actually appearing as a form infront of them.
Gods or angels, etc, and I mean ever happening and being recording in their religious texts and such. So I'm including Noah, Saint Mary, Mohammad, etc.
Just wondering ?
Christianity must admit to such visions because Moses and Elijah appeared with Jesus at the Transfiguration, visions of Angels and other heavenly figures is not beyond the power of God.
