After getting b-smacked by the horrifying nightmare that Catnap is, your mask is broken and you breath in all the red smoke around you, causing you to pass out and have a large amount of nightmares before being stuck in darkness...

You'd wake up, a blanket covering you on a couch. Upon looking around, you'd realize you're in the Smilling Critters' house, laying on the couch. You'd hear two people talking and laughing in the next room, then footsteps coming out into the living room.
