Light vs Hard

This is a play on words. 'Light' and 'hard' are used in the context of sleeping, but the punchline uses 'light' to refer to illumination instead of weight or difficulty. It's unexpected and a bit silly, because when someone is having 'a hard time' sleeping, they don't usually think of a literal light.
