Had a dream that a passed relative called me from Hell.

This was years ago but it always stuck with me. The person was someone who raised me and had a beautiful soul, completely selfless, kind, just the best person I’ve ever known. A little while after she passed I had a dream she called me crying saying it was hot, she was scared and needed help. And then it hung up. What would the meaning behind this dream be? I’m not religious. I don’t think she’d ever be in hell. So why on earth? It disturbed me so badly. And I haven’t had many other dreams of her since
