A scientific Solution 2 some religioustories

After reading a book on social culture in drugs a few weeks back I came up with this theory. E.g. The idea on explaining. Religious stories about someone going somewhere on a mission only 2 find when they come back to tell the story of where they have been(an amazing conquest with dragons, high seas etc) and it always sounds over exaggerated, it could be a bible story of monsters and parables when all along it was a fungus leave ing airbourne hallucegenics into the air we breathe. Good idea lol p.s. more realistic than the three plagues etc.
