[ SLANG ][ FANDOM ][ PSYCHOLOGY ]
A mental state where someone's personal fan theories about a piece of media feel as real and settled to them as actual confirmed canon.
REAL-WORLD EXAMPLE
"I got genuinely upset when the show contradicted my headcanon, I forgot that part wasn't even real. Total headcanon brain."
LORE & ORIGIN
Named once headcanon culture matured to the point where fans started noting how thoroughly their own inventions had overwritten the source material in their memory.
