If one sees listening or reciting Surah Fatihah in his dream, then here is the dream explanation, meaning and Islamic interpretation Surah Fatihah.
Islamic Dream Interpretation Reciting Surah Fatihah
If one sees reciting Surah Fatihah in his dream, it means fully or partially, his duas will be assuredly accepted by ALLAH Almighty. He will derive benefit and that benefit will bring him happiness and joy. And some interpreters say that he will marry seven women in succession and his Duas will be accepted. This is borne out by the fact that Prophet Muhammad (sallallaahu-alayhi-wasallam) used to recite Alhamdu lillahi rab bil alameen in the beginning of his dua as well as at the end. Source: Ibn Sirin
