What is the interpretation of a person seeing in their dream - before dawn - that they are in a place with devils and jinn and are reciting the Quran to them in order to get rid of them?

This website does not specialize in matters of visions, but the appearance of this dream is a good omen. Treating fears by reciting the Quran is a good sign. You should maintain the etiquette of sleep, its remembrances, and the morning and evening remembrances. There is no harm in going to some people of goodness and righteousness who are skilled in lawful ruqyah (definition) to perform it for you.
