“When he (Pilate) was set down on the Judgement seat, his wife sent unto him, saying, Have you nothing to do with that just man (Jesus): for I have suffered many things this day in a dream because of him”. (Matthew 27:19)
The lady’s dream was really true and quite opportune. It purports to mean that Christ be saved from the accursed death on the Cross. God saves his dear ones by means of dreams of others as was the case with Joseph who was released from jail having interpreted the two dreams of Pharaoh. God wanted to protect Jesus against his enemies, hence the dream of the Roman governor’s wife which influenced his judgement.
