if onna used her dream powers for evil:
-likely uses it to make people go mad -it's hard to tell if people going mad is because of her knoxonk side or being part Nerifen-leur, but it's likely to be made worse because they're working in tandem with each other -to get any alleviation, they gotta do what the gazes guide them to do. have a recurring dream about killing a person, but failure ends in being degloved? Kill the guy in real life! -do this enough of these, they become thralls for onna~ -Die in the dream you die in real-life, but sometimes it's not right away in bed. Death Note/Final Destination rules -towns haunted by her are the worst, there's a constant foggy haze where dreams and reality merge. Sometimes people accidentally get caught in it and end up in bed losing several hours and their sanity. -People here try to stay happy cuz any type of horror will bring out nightmares through the fog and attack the locals. So it becomes a scramble to find the sleeper to wake them up (if they wake up!) -will cause you sleep paralysis if you ignore her thralling dreams(a week of it) too much and personally meets u (sitting on your chest) -if you do your part, she'll leave u alone, but you're punished with day/night terrors -can cause a memetic effect if it breaches containment, if someone tells u about the dream grackle, ur gonna have onna in ur dream!~
-[this happens when you get swept up in a gale of fog, you'll see her huge size patrolling around the outskirts (the entity(dave) with the twiggy legs in the vid~)]
