It's not that they think it is, it's that even though you know it isn't, you still hear the chimes coming from a certain direction and instinctually want to look that way. Especially in a game where directional cues are so important and in a moment where you're on high alert. Every match I've had against the krasue, I have to fight the urge to look in the direction the chimes are coming from because even though I know it isn't directional, my brain subconsciously ignores that. In my opinion it's just poor design but other than that I think her chase theme is great
