I actually find being alone in the quiet dark incredibly calming. :)
But, I've also realized recently, that it's in the deep hours of dark night, that if I awake, I can more easily allow fabricated worries to take hold more easily than during the day. So, in that case, I guess in a dark room I am most afraid of my running imagination.
Oh -- and I forgot to mention it in my other answer- -- that's a gorgeous image in your question. The black and white colors and the use of shadows and light. :)
Ya know what. That was a pic that i had in colour but I thought it would work better, especially for this, if I shiffted it to black and white and worked on it a bit. I have too many pics.
I really like the black and white version. Whatever you did to get that black and white version, excellent. :) Thanks for posting both! Both are good! :)
