If you insist. This is a silly one.

The world has become afflicted with a virus that turns people into potential violent cannibals, that act out in frenzied rage episodes. There are naturally immune people and the afflicted only attack the healthy. Otherwise, the infected can live a regular, enjoyable life, if no contact with immune individuals ever occur.

There is no cure, only a management protocol, involving a very rigourous treatment schedule, where a serum is injected daily and very painfully. However, it has a mandatory pause, through which the individuals must either be confined or restrained.

There was a thriving and very healthy industry for the production and installation of at-home restraining apparatus, as in, they sold heavy duty steel chains and bolted six lenghts of it with big shackles on it to a sturdy enough wall for people to strap themselves in or be strapped when the cold turkey hit. DIY solutions usually involved long lenghts of rope and ball gags.

Couples where one element was immune and the other was not often got as a gift from friends and family those restraining kits.

Curiously enough, the aflicted, when undergoing an episode would try to season their potential victims with salt and pepper prior to the first bite. And victims could snap their attacker or attackers out of their stupor if they slapped them hard enough.

I woke up laughing and face palming. I am not a horror fan nor a BDSM enthusiast. I dreamed as if watching a documentary.
