it was about a moment when our Queen divided by zero... space-time continuum faded... then she fixed THE WORLD... again... But I can't find it... Perhaps it should have been vanished from memory too... and this is why I remember so vaguely...?
If it never happened on your timeline, you won't be able to find it.
When Time Travel is used to "rewrite" past events, this character will retain their memory of the original timeline—i.e., how everything went the "first time around"—even though that version of events no longer will have happened. Everyone else will only remember the new reality.
So the only way for you to remember events that never occurred in this timeline, means you must somehow have been part of the event. Was there a secret party you didn't tell us about?
