(Dreams are of three types)

Abu Huraira reported God’s messenger as saying:‘‘When the time draws near a believer’s vision can hardly be false. A believer’s vision is a forty-sixth part of prophecy, and what pertains to prophecy cannot be false." Muhammad b. Sirin said he held that visions were of three types: ideas which come from within, terrifying caused by the devil, and good news from God; so when one sees anything he dislikes he should not tell it to anyone, but should get up and pray. He said he disliked seeing a shackle on the neck in sleep, but that people were pleased by a fetter, as it is said that a fetter indicates being firmly established in the religion. Bukhari and Muslim.
