Dreams have been playing a very imprtant role in the spirituality of Judaism and Catholicism.

[20] The angel of the Lord: in the Old Testament a common designation of God in communication with a human being. In a dream: see Matthew 2:13, 19, 22. These dreams may be meant to recall the dreams of Joseph, son of Jacob the patriarch (Genesis 37:5-11:19). A closer parallel is the dream of Amram, father of Moses, related by Josephus (Antiquities 2, 9, 3; 212, 215-16).

The Christians hold that these dreams were working of the Angels commanded by GodAllahYHWH to help in need.They support the believers and depict God's verdict in a situation.
So what saint Claudia saw in a dream was a message from the angels to her and through her for her husband as to what he was to do in the event of Crucifixion; which was naturally to save Jesus and not to kill Jesus. If Pilate could not do it openly; he did it , one could see it through the gospels though hidden behind the apparant words, in my opinion.
I love Jesus
