Hello. I've read this sentence in a book :
"She blinked, surprised, and her lashes swept her cheeks."
I can't follow the underlined part. How can lashes sweep one's cheeks?
It could be a hyperbole (exaggeration) about the length of her eyelashes, and we are meant merely to understand that she has uncommonly long eyelashes. She could be wearing eyelash extensions... perhaps an exotic fantasy style that flair out to the sides.
Most Western women do not get anything this extreme unless they are fashion models. Those who get moderate eyelash extensions or have long lashes consider it fashionable to curl the lashes up so that they will be more visible from a distance, which also decreases the likelihood of their being able to touch the cheek. In another culture, they may have a different style or ideal of beauty. Long lashes which droop down will come closest to touching the cheeks when the eyes are closed, not opened wide.
Otherwise, the observer in the story (or the writer) may be delusional. It does sound like the romance language of dime novels.
