An old friend told me I was going to die

This friend Elizabeth, who I knew in 3rd grade and haven't seen since, was older now with longer hair. She was there with my late great grandmother, who looked how she did before she passed. Elizabeth told me I was going to die soon and so I should prepare. I accepted this like it was nothing. She might as well have told me the weather. I began to writing down in a book about everyone I had known and loved throughout my life, and the impact they had. Then I woke up.

I am honestly rattled by this. Elizabeth, when I knew her, came from a troubled family. Her mother had moved her and her sister into town to escape from their father. After a year, they returned to their hometown and I never heard from them again. I don't remember her last name and I can't find her information anywhere.
