Sim looks dead but not?

Not sure if this is just something I have never seen before. These Sims were laying on the ground in the position of death (not like passed out with butt in air but laying on side). It was ghost night at the Gnomes Arms bar and there was a rampaging werewolf ghost. So maybe it's a new kind of passing out for werewolves? Can anyone confirm if this is the case? I didn't see the Sims pass out. I could see them breathing laying there and I could click on them and get a social menu and then they jumped up and ran away scared.
