Salaam, I dreamed when I was 9 about the Prophet saw, on 8 about i was with grandfather Achmed in paradise but a big door was closed. on 30 about prophet Isaa that he come on earth. 33 about Surat al-Kawthar and now about black dogs that catch me. Sukran zazak
wa ‘alaykum salam,
Dreaming of the Prophet (s) is the best thing you can get, as it is a certificate of Iman and a guarantee of the Prophet (s) intercession in seven serious situations in this life and seven in the Afterlife. You had an elevated spiritual state, based on the earlier dreams, but now your ego and worldly desires are attacking you and your state is dropping. The earlier dreams are encouragement for Akhira and its `amal, so stick to that, and Allah knows best.
