I came up with an idea for a curse that uses Meta Information aka the "Deadpool" Curse.

It can be a curse bestowed by an extremely powerful item, and causes the victim to be aware that he is a tabletop character. He can understand the cliches, he can be genre savvy, he can even understand what roll someone had "Oh the Orc rolled 1, that's a miss", "The Lizardman is CR 1/2 we can take him guys" . The curse part comes that nobody will ever believe him, and he either shuts up but lives with the knowledge that his reality, his friends, enemies , gods is simply a construct and a slave of a random DM, or his tries to inform everyone and he gets locked up as a crazy dude.

EDIT: Using "Deadpool" kinda gave the wrong context. I am thinking something along a Lovecraft kind of curse, not "poke the fun at rules" comedy.

I would love to hear our opinion.
