Why "Whispers in the Dark"?
It would be fittfully dramatic to say something like "when I raise my voice, I'm often unheard, and so I feel like I'm 'whispering in the dark'".
But it would be much more honest of me to say that my best thoughts come to me in the middle of the night when I'm trying to sleep. I like to talk to myself, but I can't wake anyone up, so I have to whisper.
Now aren't you glad you asked?
