A good dream is from Allah

الرؤيا الصالحة

He ﷺ said: the good dream of a righteous man is one of forty-six parts of prophecy. He ﷺ also said the truest dreams are at the end of time. A good dream is glad news. It is not a new ayah. You thank Allah. You may tell it to one you love. You do not build a masjid on it, and you do not marry because of it, and you do not accuse a person because of it.
