One night recently, I forgot I'd left the Classical station on before going to sleep. When I woke up, soft, angelic music was playing.
I mused to myself, "How did that happen? I don't remember turning on any music. Am I in Heaven? Does Heaven replicate my living room? And is that Collette playing the cello? If so, that's impressive for a cat. No, wait; Collette's sleeping right over there."
The station must have been playing a recording of Collette playing the cello; that must be it.
