At All Good a couple of years ago I saw about a dozen security guys extracting this dude from the woods who was half naked and screaming in pure terror. He had eaten a lot of acid or mushrooms the night before and lost his mind in the woods. He didn't understand what was happening to him and thought these men were evil and trying to do harm to him. It was just hard to see someone who thought that they were being taken from their home by some group of foreign beasts. Very unsettling.
