Aslam

(1) True dream. It reveals the unseen events. When it is possible in dream, it does not become impossible in wakeful state for the following reasons. In sleep, actions of the outward senses remain closed and suspended and soul remains free from the engagements of the material world and then the door of the knowledge of soul remains a little open towards the spiritual world. This occurs sometimes in wakeful state. There are many men who don't hear and see even in wakeful state as they are then remain immerged in their thoughts.

(2) Prophecies of Prophet. With regard to the prophecies of the Holy Prophet concerning future events, there are proofs in the Quran. A prophet is he who remains busy for the Quran. A prophet and to whom the real nature of everything is disclosed.
A friend of God is he who does not remain busy in the affairs of the people but it is possible for him to know the real nature of things. There are two gates of soul. He who believes in the prophets and in true dreams must believe that there are two gates of soul, one gate is opened to the external senses and another to the spiritual world from the deepest recess of soul and that is Ilham or blowing of Run or inspiration or revelation. Between these two gates, the roaming of soul discloses its real nature. As spiritual masters are disclosed in dream, they are disclosed similarly to the prophets and friends of God in different forms. It cannot be understood without spiritual knowledge.
