Hakeemul Ummah Hazrat Moulana Ashraf Ali Thaanwi Sahib رحمه الله has stated that people deem their dreams to be wahi (revelation). The deviate spiritual guides have corrupted the thinking of people. What is not the objective (Maqsood) is believed to be the Maqsood. This is indeed corrupt. The focus is taken away from the actual Objective; i.e. the Shariah. Dreams are unreliable. In fact, most dreams are not valid dreams. They are mere imagination. Also, dream interpretation is a subtle issue. There is no certitude that the interpretation given is valid.
COMMENT (MUJLISUL ULAMA)
People are enarmoured and awed by their dreams which in most cases are the effects of their ideas, thoughts and what they mentally absorb from the environment. Ignore dreams and concentrate on obedience to the Shariah. Then, one need not be fearful of bad dreams. Just recite Ta-awwuz
أعوذ بالله من الشيطان الرجيم
or لاحول ولاقوة الا بالله and
make duaa for aafiyah and safety.
