What is the interpretation of seeing a man of light appear to someone who failed the baccalaureate, while he is sad and crying?

The believer is tested with both good and evil, and must endure tribulation with faith that it is decreed by Allah. This brings tranquility and contentment, for "No disaster strikes except by permission of Allah. And whoever believes in Allah - He will guide his heart." What appears to be evil may, in fact, be good for the Muslim, for "Perhaps you dislike a thing and it is good for you." As for what appears to you, if it is in sleep, it is a good dream. If it is while awake, it may be from the Jinn or Satan. This will not harm you if you frequently recite the Quran, especially Surah Al-Baqarah, and adhere to the remembrance of Allah (dhikr).
