I don't know much about the white/pink noises but when I sleep, I leave the TV on so that talking is just going on. It seems like that keeps the thoughts from getting into my brain & seems to eliminate my dreams.....but so does the seroquel I take.

However the other night, I fell asleep with an actual show on the TV & I ended up having a horrible dream....& woke up suddenly....to my surprise, the yelling of the words I was dreaming about was coming from the TV & entered into my mind translated into a horrible dream. I have learned to keep the TV on something like QVC or HSN where nothing emotional is going on & just the drone of talking.

It wasn't until that experience where I realized how much influence the background noise has on my mind. Noise without talking also allows words into my mind.....so have to be careful about the words that enter.

This is a fascinating topic,
