I was hiking in a wilderness area...a very remote trail without a lot of action, and at one point I heard voices...I swore I heard human voices.
It was up in the mountains, too, so there wasn't much to make noise like that.
Obviously, I know it's my brain hearing trees groaning in the wind and quickly shortcutting to, "must be a human voice!" But it was just eerie.
I have this too and sometimes use white noise or nature sounds to "reset" my brain when it gets too intense - the soundleaf app on my phone has been a lifesaver for managing it when I'm tryng to sleep.
