The purpose was to describe "crazymaking", or how Conservatives drive some people particularly nuts.
The Conservative message is crazymaking and requires one to believe two mutually exclusive ideas simultaneously.
The "go to sleep" was meant to illustrate the Conservative answer to all of these conundrums.
"Hey, that was yesterday." "We already dealt with that." "Old news."
Just relax, go to sleep, and trust.
