These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Nightmare Fuel: Kind of — when everyone blinks their eyes, their eyelids don't bat at the same time, giving the impression of them being "a little" deranged. This can pass unnoticed (this troper in fact didn't notice it the first time), but when you focus on it, it becomes slightly unnerving.
