We had this thread before and some good ideas came out of it.
So What were some misconceptions or notions you had as a kid, have you ever used them to inspire lore for a game?
As for myself, I just believed prairie dogs were actually small dogs and wondered why nobody kept them as pets.
Some gems from the last thread: >I believed that every time you opened a door, there was a chance it would open to Hell, or just to darkness. Like, 999,999 times out of 1,000,000 you'd be okay. But there was always a chance you'd just die and be damned forever.
>When I was little an older kid told me that dwarfs/gnomes existed and they had shotguns that they would fire through peoples window at night, and told me that his grandma was killed by them.
>My parents always told me never to go into the old factory near where we lived because it was a "deathtrap". Misunderstood and thought that meant that a thing called Deathtrap lived there and killed anyone who came in, only strengthened my belief when some teenager managed to set himself on fire when trying to arson the place, thought there was a fire demon or something hiding in there.
