The 'Peter Is Going Insane Theory' (also known as the Peter Griffin Coma Theory) is a popular internet creepypasta and fan hypothesis suggesting that the events of Family Guy are merely hallucinations of a dying or mentally unstable Peter. The meme template typically features a screenshot of Peter Griffin looking uncharacteristically somber, exhausted, or shell-shocked. It gained traction on platforms like TikTok and Reddit, where users pair the image with unsettling music or detailed 'evidence' that the show's cutaway gags are symptoms of his fracturing mind. Beyond fan theories, it is widely used as a relatable reaction image for being sleep-deprived, overthinking a simple concept, or reaching a breaking point after a long day of mental exhaustion.
