the dream of the square contact lenses

It was a slightly frustrating dream. The contact lenses were square, and I was somehow supposed to peel them off a plastic sheet. My mind was grappling with everything that was wrong with this picture while an unfamiliar man with curly, black, shoulder length hair was trying to get me to try them.

In the typically characteristic way that the subconscious seems to illustrate familiar figures of speech, I realized that the square contacts are a clever play on "putting a square peg into a round hole".
