Sometimes, everything in your novel is going crazy. One character has turned into a chimpanzee, there's a volcano that just appeared in the living room, and your antagonist just declared a deep, undying love for the Precious Memories collection. It is bad.
At times like these, you have one of two options: either treat everything as normal, or admit the obscure. Both work, but this week's feed is to add a character--or use an existing character--to admit that everything is out of control. Have a character act like you do, and just be confused. Wink towards the audience. Admit that it is ridiculous that a volcano appeared, or that someone actually likes Precious Memories.
Acknowledging the insanity is sometimes the best was to solve it.
