What is the interpretation of the dream of the questioner seeing their deceased neighbor, who entered the house and asked for their sick daughter, who passed away two hours after the dream?

What you saw may be a true vision, as a believer sees visions that contain unseen news about the future, and this is part of prophecy. It could also be from the inspirations and unveilings that some righteous people experience, as was the case with Umar ibn al-Khattab, may Allah be pleased with him. Divine inspirations are granted to those who are steadfast in Allah's law, and they differ from satanic suggestions. The occurrence of inspirations does not imply the superiority of the one who receives them. It is preferable to seek out specialists in interpreting visions, and to be pious and stay away from charlatans.
