Some more late-night (in my case, early-morning) cats with animals at various locations around the campsite.
In real life, I sleep best in absolute silence, but that’s literally impossible at my current house, so I sleep with a fan on instead. That might sound completely contradictory, but the idea is that having a small amount of noise that’s loud enough to drown out things like my furnace kicking on, the sump pump pipe pushing out water, outdoor car sounds, and anything else that might be going on outside is better than NOT having that and instead having to deal with all those little noises as they pop up.
I was once roommates with a guy who slept with earplugs in. I sometimes wonder if that’s a viable option.
