That's usually why I use it Sometimes situations or conversations get so strange it's like you've been transported to Oz. Or the Twilight Zone
I also use a variation of this too shall pass but I use the George Harrison version.
I used to use a line from The Fellowship of the Ring where the hobbits are passing through the Old Forest. Something about not singing cheerful songs until they were almost out of the forest (anxiety & depression) when they would turn and give a rousing (razzing) chorus.
