Well, it is based on an SCP, which I made up, but inspired by other "reality altering" SCPs.
If you are interested (not baiting you or anything, or am I?) currently I am trying to finish a game, called "The Lamp Post", which is an actual SCP, you can look it up. You are kindly following me both on YT and here, (again huge thanks for that) so once it gets published you can see the result.
