Face swapping while vaping is what nightmares are made of

As if Snapchat's Face Swap feature weren't creepy enough, one Canadian duo (impressively) found a way to make it even more terrifying.

Perhaps the first people to attempt the art of the "swap" whilst vaping, Dorrit Shank and her boyfriend Cory Dickinson's experiment has gone viral for the ghostly effect it produced.

Simply captioned "Vape + Face Swap = FACE VAPE," the video shows the couple trading faces as Dickinson takes a puff of his red pen. As he exhales, suddenly Shank's face begins to float along with the smoke, eerily shifting side to side towards the ceiling like a Scooby Doo villain.

As for Dickinson, he's left with a skeleton-inspired look that seems to be due to his face getting lost in the fumes.

The couple begin hysterically laughing at the snap -- an effect that they seem to have shared with the video's near two million viewers.
