Don't just list facts. Describe the physical sensation of two lives colliding:
"This world is exactly like the video game I played before I died." 1 : I Recalled the Memories of My Past Life...
Trying to see if they can still do math, cook, or use "future knowledge." 5. The Hook End the chapter with a realization that raises the stakes: Don't just list facts
"Why is there no plumbing?" or "Wait, is that magic?" 1 : I Recalled the Memories of My Past Life...
Catching their reflection and realizing their face doesn't match the "soul" they feel inside. 2. The Mental Sensory Overload
High-pitched ringing or a blur of images (subway trains, office lights, a hospital bed).
"I remember why I died... and the person who killed me is in this room."
