The 'dimming of the lights' is an example of a ritual to initiate this for some (centering and focus).
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 :)
