I wrote the following:
Eri was still staring at the screen, but her eyes were expresionless, as if in a trance.
Her father laughed. "I admit it was a shocking footage. But Eri, you look like you've just seen a ghost."
"Oh," Eri said, snapping out (of it). "It's nothing. I just had a long day."
Should I just write, snapping out, or snapping out of it?
