Hallucinations while lost in the forest

There's a youtube video that has stories of people lost in forests and these people often have wild stories. The story that intrigues me is the one where a lost person saw people hiding behind trees and when they were approached for help they walked away.

Are these people seeing things that aren't there or do some people live in the forests who don't care whether an outsider lives or dies?
