Apparently. I first learned about this last year when a co-worker told me to listen to my inner voice. I said, " oh yeah, like Sybil or Jiminy cricket?" I thought she was kidding. Then I thought she was crazy. Then 2/3 of my office said they hear it too. People who hear don’t believe that other people don’t, and vice versa. People are always trying to trick me into saying I hear something by asking me how I know the sound of my husband’s voice or recognize a song, or get a song stuck in my head. When I have a song stuck in my head it’s just the urge to sing it and there’s no music. I can recognize actors by their voice sometimes, but I cannot do impressions or accents at all!
