It is narrated from Hazrat Auf bin Malik Ashja'i that the Messenger of Allah, peace and blessings be upon him, said: Dreams are of three types. Some dreams are from Satan to frighten, and some are matters that a person thinks about while awake, so they appear in dreams, and some dreams are the forty-sixth part of prophethood.

It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: Dreams are of three types; some dreams are glad tidings from Allah Almighty, some dreams are thoughts from the heart, and some dreams are from Satan to frighten. When any of you sees a good dream, he should relate it if he wishes, and when he sees a disliked dream, he should not tell anyone and should stand up and offer prayer.

It is narrated from Hazrat Alqamah that Hazrat Abdullah (may Allah be pleased with him) said that dreams are of three types: some dreams occur due to the coming of Satan, and sometimes a person talks to himself during the day and sees the same in his sleep at night, and some dreams are true dreams.
