>>1372766I would consider "afraid of normal person doing normal things and not jump scaring you, either for no reason or because you can't be assed to look up from your cell phone once every 5 minutes" a startle reflex, even if it isn't the traditional jump scare startle.
I mean I've had people burst into hysterics upon encountering me, at distance, in public places where you should reasonably expect to encounter people, simply because they're high strung or have whichever scary movie is trending at the time in the back of their mind and go "hey that guy in jeans and a tee shirt fishing this public lake less than a mile from the parking lot can be absolutely nothing other than Jason Voorhees himself!"
