I am glad to see I am not alone! It was very beautiful, and it lasted a while until I drifted off to sleep. It was disturbing enough though that I had to get up and search my entire house to try to find where it was coming from. I even went outside to see if it was my wind chime, since I have one of those huge bamboo ones on my front porch, but there was no wind. It is just odd. It was very calming once I laid back down to go to sleep.
