My dog happily sleeps with all kinds of noise going on. While he's fairly smart I think there's not a lot of introspective thought in his brain. Probably the same for a kid compared to an adult, or an anxiety-ridden adult compared to a more healthy (if that's the right word) one. My wife can turn off and sleep in under 5 minutes, but leave me alone with my thoughts in the quiet and dark and I'll tell myself stories for hours in a very alert state where tiny noises make my heart race. I don't remember being like this as a child.
