Looks like an number of use white noise to drown out the chatter/music/in our heads. Interesting. I used to use alcohol, bad idea I know, but then I met my wife and quit drinking and she has always needed a fan (or white noise) to sleep, I just adopted that from her.

As a child, I HAD to have music playing, and I would rock back and forth in bed (violently) until I fell asleep, often only getting 3-4 hours of sleep as a kid...

My wife says, I still rock gently in my sleep once in a while. Strange...wonder if I can get to tell me when I do it and see if it ties to anything different in my mood chart...like a hypomanic phase.
