Is it right?
All her memories were passing in front of his eys.
Are you writing a fantasy novel in which a character can see into the mind if another person?
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
I see. That would be "memories of her" not "her memories." The latter are in her head and unless you have magical or psychic powers, you can't see them.
