Hats off to this couple, who briefly managed to convince Twitter users that demons are real and walk the earth among us.
This week 'andy' posted what at first appears to be another innocent selfie of a young couple in love, joining the forty-eight trillion identical photos in cyberspace.
Look a little closer at the background though, and feel your stomach drop: instead of the back of her head in a mirror, you see andy's bae's face. Chilling.
Of course it's a Photoshop. The clue is in the caption about her being a Gemini - as well as, you know, physics - but it's a good job nevertheless, and an amusing subversion of social media vanity posting.
Also a handy reminder not to trust a single image you see on the internet.
