I like to call it nighttime brain: the way your mind seems to function on a different frequency than it does during daylight hours - which can be good or bad but also can lead to unexpected epiphanies or experiences that wouldn't be the same at any other time of day. ↗
I also used these realistic sounds in a psychological way. With The Good, the Bad and the Ugly, I used animal sounds - as you say, the coyote sound - so the sound of the animal became the main theme of the movie. ↗
I'm just looking as always for something that's stimulating and I hope to find a good story that's a challenge, whether it's big or small. Or that it finds me. I don't have like a career plan. Maybe I should, but I don't. ↗
