Contacting my late idol/hoping for her help/just talking to her?

My greatest hero (a semi-celebrity I guess, though you probably won’t have heard of her) passed away 8 and a half years ago now.
I’ve felt a great connection with her during the last 3 years or so especially and I would love to speak to her, in best case scenario ask her advice/help on a situation in my life that she would have understood and related to massively during her life. I desperately would love to talk to her, and I just saw a post from someone explaining how the spirits of the dead can be equal to or just as good as those of the demons because there human and can understand in a human level. I believe this persOn would understand my personal situation better than anyone. Is it possible to do this?
