I've been spinning this vague idea in my head about an SCP that works as an anti-amnesiac - in other words, something that forces its subjects to remember everything they have ever remembered. The danger of this SCP would be twofold - first of all, the mind of those subjected to it could not handle having to remember everything, and second of all, it could be a safety risk due to the possibility of canceling out Foundation amnesiacs.
I have no idea whether this thing could be a substance (and thus possibly in a limited quantity), a device/item that gives the effect in a certain range or by close contact, or something more abstract like a certain sound.
I'm sorry if there already is an SCP like this, I don't remember having read about such. Could this idea work as an SCP?
