Similar to King Brown's story, I relate to my Junior Hunter Safety Course kids how I got lost on my own farm deer hunting. It got dark and I walked straight through, (I thought) a 10 acre patch of bush heading towards my yard, and wound up within 20 feet of where I started in. Yes, you can go in circles without being aware of it. I have heard that and now believe it to be true. After that I always take a Mini Maglite flashlight and a compass,a compass does not have batteries which run down like a GPS, although I carry one as well if I am far from home. I have another story, scared stiff, panic stricken, to the extend I thought my compass was "broken", lost in a bog, duckhunting on my own.
Cell phones have reduced the dangers too, where they can get a signal
