You'd think that it being All Just a Dream would let you do lots of cool and risky things, since it's not real anyway, and you therefore can't get hurt. Not so. There's an old wives' tale which claims that if you die in a dream, you die for real. It's not exactly clear how anyone could have determined this, since the only witness would be unable to confirm it. Yet it persists, and a lot of people believe it. This tends to apply to video game levels that are All Just a Dream or a virtual reality simulation as a function of gameplay: If your character dies, it's still a Game Over.
