The device or technique I'm looking for is used to describe something mundane or ordinary in order to make it seem alien or special.
For example, the following quote from Slaughterhouse Five:
In a tiny cavity in her great body she was assembling the materials for a Green Beret
In that instance, a woman becoming pregnant is described, but it is written in such a way as to make it seem completely foreign. I think Hemingway was also known to use the technique, but no examples come to mind.
I've read briefly about the term before. I remember it being called something close to "dissociation." I'd like to read more writers that use the technique and practice it myself, so I'd like to know what the precise term is.
