Bright or Dim?

Have you ever noticed that when listening to music in your listening area that music seems to sound better with the lights down? To me there is a rather noticeable difference. Could be just in my mind because that's how I like to listen, or is it something more biological/scientific than that?  Could it be that the lessoning of one sense enhances the other? Maybe it's just me. Anyway I thought I would see if anyone else has the same experience. Im sure if there is an actual reason for this phenomena, that someone on this forum will have the answer :)
