During the Salem witch trials, members of the Salem community fed on a type of grain, that, due to the climate, developed a fungus with the same chemical composition as LSD. Of course they would not have known that at the time. While small doses of LSD over long periods of time may not be so bad, eating huge portions of rotting fungus in the forest that happens to also contain the drug as well probably is not the best idea. But that did not really matter, did it? They proceeded to hallucinate ghostly apparitions, and view these hallucinations as "reality". This is how easily, and, far more important, how stealthily madness infects the human brain. But is that really what we would call insanity? After all, they were not aware that the drug did such things, nor were they aware the drug was in their food at all, nor were they aware that bad conditions could lead to food poisoning. Is that crazy or just unlucky? Then add to this their religious fervor. They believed the holy scripture wholeheartedly, so much so that their hallucinations justified said text, acting as a kind of proof of the spiritual realm. Most everyone was having essentially the same hallucination, so they were even able to confirm their biases with one and other. Since they believed spiritual warfare was at hand and they were living in a state of prolonged panic and fear, they began to behave more and more irrationally by the day. Even those who initially denied the existence of these other worldly beings eventually admitted they could see them. Did they really see them? Was it just peer pressure? Or was it a combination of both, dual delusions working together in perfect synergy to destroy reality and goodness? Is that really crazy? Or are we just living in a mad, mad world?
