Had a dream where my recently diseased friend gets in my car when we are about to go to her funeral?

My friend died exactly two weeks ago. We werent close friends but i would see her everyday. We barely talked to each other. She would always have a smile that you can see from a mile away. She would always be surrounded by friends who loved her. I really felt devastated when i heard she passed away. I couldn't believe it. Well my dream happened a day before her funeral and in the dream it was the day of her funeral and we were going to carpool, so i was at my high school with my truck and a black car behind my truck. I was there with a group of girls ( our friends ) and she was there too, she was wearing a light pink or white gown and smiling. she didn't say anything but I did notice that she was floating and when i said " Ok, lets go everyone ". a few friend got into my truck and so did she. what could it mean that she was there and that she got into my truck?
