What is the definition of Silent Night Stille Nacht?

"Silent Night Stille Nacht" is a German phrase that humorously concocts the idea of a night so quiet, it's practically a stand-in for the existential dread of being in a horror movie. Imagine this: "After my therapist's 'Silent Night Stille Nacht' sleepover, I realized my room is practically a vacuum cleaner of silence, and I'm questioning if I should've just brought a snooze button." This is the kind of night where even the crickets might be auditioning for 'ghost in the night' roles, but they're not actually there. Now, here's a darker take: "The janitor, hearing the creaks of the old building at 'Silent Night Stille Nacht,' decided to start a new shift as a 'ilent night stille nacht' ghost."
