What does it mean to dream of Imam Ghazali wearing dark orange clothing and giving a khutba?

I once dreamt of Imam Ghazali (RA). He was fair and strong. He had long white shoulder-length hair and long beard. His clothes were dark orange in colour, orange turban and orange kurta, vest and lungi. He was giving khutba. I was looking at him in the face. He looked very serious. Please interpret.
