Daniel 8:27

"I, Daniel, was exhausted and lay ill for several days. Then I got up and went about the king's business. I was appalled by the vision; it was beyond understanding." NIV translation

Daniel was so shaken by this vision that he became sick. After his recovery, he went on with his life of service to the king. That is a good lesson for us as Christians because many people get so caught up in prophecy that they don't pay any attention to what is happening now.
