. dear mufti sahab I am a 18 year old and I am unhappy these days as I could not succed in a very important exam to become a doctor .I am suffering with sleepless nights and usually sleep during the morning to compensate for the nights sleep. when sleeping during the day between fajr and zohr I dreamt of being happy with many of them and after that in the same dream I saw many snakes and someone was holding them and making the snakes bite all over the face. I am sure that in the first part of the dream it was me being happy but when I dreamt of snakes I am not sure if that was me who was cathing the snakes or recieving the snake bites.please interpret this dream and let me know some duas or amaals to lead a happy life .
