I am with you on the socks, the dark, and fresh air. When I travel for work, the hotels can be so bright at night. Even at home, the moon can be so bright sometimes, and the town lights reflecting off the clouds, too. So I use one of those soft, snuggly headbands that people wear for cross-country skiing. I pull that over my eyes and everything is so soft and cozy and dark. I can have my window open for the fresh air and sleep so, so well. It's changed my life for the better.
