In Islam, true dreams are "one-fortieth of prophecy." Prophet Muhammad classified dreams into three types: divine, demonic, and personal. A special prayer – Istikhara – asks God for guidance through sleep. And the world's longest continuously published dream dictionary is Islamic – over 1,300 years in print.
Prophet Muhammad established one of the clearest dream classification systems in any religion. Three types of dreams exist: Ru'ya – a true, good dream sent by Allah. It is considered "one-fortieth of prophecy" and should be shared only with trusted people. Hulm – a false, disturbing dream from Shaytan (the devil), designed to frighten or mislead. The prescribed response is to spit lightly three times to the left and seek refuge in Allah. Hadith an-nafs – a dream from one's own mind, reflecting daily worries and desires.
This three-part classification resonates across traditions. Macrobius classified five dream types in Rome. The Talmud distinguished divine from mundane dreams. The core question is universal: which dreams matter, and which are noise? It is the same question modern dream science still debates.
"True dreams are one-fortieth of prophecy."
– Hadith of Prophet Muhammad (Sahih al-Bukhari)Salat al-Istikhara is a special prayer performed when a Muslim faces a difficult decision – marriage, career, relocation, any crossroads. The person performs the prayer, then sleeps waiting for a dream that reveals the right path.
This is not ancient history – it is living practice. Hundreds of millions of Muslims worldwide perform Istikhara regularly. It represents one of the most widespread active dream practices on Earth today, connecting modern believers to a 1,400-year-old tradition of seeking divine guidance through sleep.
The practice has parallels in Egyptian temple incubation and Greek enkoimesis – all share the principle of deliberately seeking a meaningful dream through ritual preparation.
For 1,400 years, Muslims have sought answers in sleep. Our AI interpreter respects all dream traditions.
