Please give more context to this vision. Did you see anything additionally?
When I think of olives, I think of crushing/process. Olive produces oil, which we know is good for skin and is used for anointing oil. The Mount of Olives was a sacred place, where Jesus taught and also was before he was crucified. It was a place of surrender; a place where a transformative and necessary decision had to be made. “Not my will but thy will be done” type of moment. I would study Mount of Olives and see what message you get from it.
Hope this helps.Blessings!
