Guan Yu's position before his death was only a general; "Hanshou Hou Ting" is just a gift of "township level" treatment. Guan Yu didn't use Guan at first, but changed his name because he killed someone.
There are signs in MUBI. I think this dream implies that there are villains around you, and it is your superiors or leaders who can help you. They will find Guan Yu and send him to help you.
Suggestion: Do your job well or study hard or yourself, and "God" will help you.
