I do something like this, but instead listen to recordings of the animals from where I grew up. (Frogs chirping, rain in forest, and Barn Owl calls. Really relaxes me.) Also, I have found that if I watch a bunch of something that will make me laugh before laying down it helps. (Stand-up, comedy panel shows, Try Not to Laugh videos, etc.)

laughing helps because it makes you breathe.
