I had a dream of my dead best friends eyes,they were looking at me so trusting.What does this mean?

My best friend died 2 years ago of cancer she was 17.I havent dreamt of her in a while.i went to bed feeling quiet down & had the dream.All i could look at were her big blue eyes of hers it was so real,but her eyes were on childs body,it wasnt her just her eyes! I new it was her & she was just looking at me so trusting.What does this mean i really need to know?
