The Revelatory Dream of Imam Husayn(A.S.)

Before dawn on the day of Ashura (the tenth day ofMuharram, the first lunarmonth ofthe Muslim calendar) the Imam(a) had a revelatory dream. He said he saw a pack of rabid dogs attacking him and among them was a dog spotted like a leper, which was the (fiercest of all. Shimr who eventually personally killed the Imam(a) was a leper.
In a second dream he saw his grandfather, the Prophet(s) who told him that he would soon be joining the divine folk. And so, his dream came true on that very day of Ashura. (Maqtal of Kharazmi vol. 1, p. 25 r and Bihar al-Anwar vol. 25 p. 3)
The first dream depicted the true nature of the enemies of the Imam(a) and the second depicted the divine certificate of merit given to him by the Messenger of God(s).
The battle of Karbala was the human conflict between truth and falsehood where although the disbelievers had apparently won the day in reality it was the believers who were victorious.
