Reality warping is a cool power, isn't it? Definitely. But here is the catch. It can make your dreams come true, but not all dreams are good. So what happens when a Weak-Willed paranoid person becomes a Reality Warper? Things go Horribly Wrong pretty quickly - suddenly the monsters under your bed are real, your Imaginary Friend becomes an Imaginary Enemy, all Paranoia Fuel becomes real, and in the worst case scenario, you could end up in a Self-Inflicted Hell. Often used as a Fantastic Aesop on why only select people like God can have such power.
