You'll hear things running around. nothing will bother you. Most likely, you'll hear mice and rodents in the leaf litter. You have to just trail your rational brain to overcome the fear of it. I've gotten to where it doesn't bother me, up to the point where the mice are running over my face while sleeping under a tarp (don't like that). or my favorite, was deciding the skritchy noises were too close and looking out of my hammock to see a porcupine rummaging around under it looking for salt (sniffing and licking my trekking poles). Fortunately my boots were hanging on my hammock strap so he didn't chew 'em up

I've heard and seen moose walk through my camp. deer many times. nothing that
walks around at night will bother you, unless you go about slathering yourself in dead fish before you go to bed or something.
