Li Shimin, Emperor Taizong of the Tang Dynasty, was hunted down by Bo Liao officials. He was rescued by a young man in white robes when he was in danger. It turned out to be a nightmare. Military advisor Xu Maogong interpreted the dream and said that the white-robed young man in the dream would be the future pillar of the country. The "virtuous minister in the dream" was Xue Rengui from Longmen County, Shanxi Province.

So I think this sign should indicate a bright future for you, and you will meet the noble person in your life.
