The Roman Emperor Augustus was approached by a friend and informed he was in grave danger. The friend explained he had received a dream warning him that the Caesar needed to relocate from his tent. Initially Augustus refused as he was quite ill. However, the friend continued to pester the Emperor and finally he relinquished, removing himself to a new camp.
A few hours later that evening, the campsite Emperor Augustus had evacuated was captured by the enemy. The tent previously occupied by the Caesar, in the very spot he had been sleeping, was pierced with many enemy swords.
