Oh, it's definitely symbolic, the question is of what? I don't think it was a real ghost any more than the "ghost" of Hamlet's father was a real ghost. I think it symbolises the power that Summer Rose's history and fate has over Ruby. In her own way, she is as much haunted and driven by those before her as Jaune has ever been.

My theory?

White Cloak = Summer Rose = Crimson.

"There is still good in her, Professor Ozpin! I felt it in her when she hesitated to kill me!"

"She's more Grimm than human now, Ruby... Twisted and evil."
