Is it true that reciting Surat Al-Insan before sleep leads to beautiful dreams, stops nightmares, and fulfills wishes?

There is no connection between Surat al-Insan and dreams or nightmares, and there is nothing in the Sharia that proves this. Visions are of three types: a righteous vision from Allah, a frightening one from Satan (a nightmare), and a self-discourse. To counter nightmares, it is recommended to spit to the left three times, seek refuge in Allah from their evil, not tell anyone about them, and turn over from the side one was sleeping on. These nightmares are from the manipulation of Satan, so it is recommended to maintain the remembrance of Allah before sleep, such as reciting Surat al-Ikhlas and the Mu'awwidhatayn, the last verses of Surat al-Baqarah, and Ayat al-Kursi.
