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.
Too much caffeine.
And it’s not really pareidolia what your describing. Just auditory hallucinations.

Pareidolia refers to the tendency to see faces in things. Not recognising humans, as such, or imagining things.
