Why do you need a memory at that point? I guess it’s possible her brain would latch onto something comforting, but she’s also in complete shock. I imagine her brain would barely be able to process what she’s seeing, let alone pull up a memory. I think if you want to put something like that in there, maybe you alternate a memory with what she is seeing, and keep it short. Something like this maybe?
Her father’s distorted face looked back at her. Daddy reading a bedtime story. Cloudy, milk-colored eyes. Opening presents on Christmas morning.
Just an idea. Not necessarily a good one.
