What is the literal and figurative meaning of "snapped out" and "accidental" in the following excerpt from The Great Gatsby, Chapter Seven:
They were gone, without a word, snapped out, made accidental, isolated, like ghosts even from our pity.
In the first chapter of The Great Gatsby, images of light are introduced with the sunshine of summer, The French windows of Daisy's house glowing with "reflected gold" from the sun, and t6he lighted four candles that flicker on the table in the soft wind.

The Buchanans plan to make Mrytle's killingappear to be a hit and run by Gatsby, the owner of the "yellow death machine." As "careless people," they can easily "snap out" Gatsby's life and not feel badly because he was not one of them.
They smashed up things and creatures and then retreated back into their money or whatever it was...
