It is the basis for about 90% of the fear of jumping in horror films: the victim looks around, is sure that someone is watching them, and as soon as he is certain that he is imagining things, he is murdered extra.
But that’s a real thing everyone has experienced (the weird feeling that someone is watching you; most people are lucky enough to live a life without tricks). How does it work? Did we just convince ourselves that we could do it because we saw it in so many horror films? Which came first, the chicken or the trope?
It turns out that you don̵
7;t create the feeling of “going to the hairdresser because of the hair on your neck”. However, it is not a sixth sense thing, just one of the boring big five: the miracle of the human eye. It’s a system that is so fine-tuned that it’s one of the most successful arguments in favor of intelligent design, to the point that we can see someone looking at us even when we aren’t looking at them. We can determine it so precisely that you won’t get a tingling spine if the person’s gaze deviates only a few degrees. Even blind people can do this as long as they have something called “cortical blindness”, which means that their brains still get input from their eyes, even if they are not aware of it. The person looking at you just has to be somewhere in your field of vision, which is wider than you might think:
That means you have no eyes in the back of your head, just really good ones in front. If you catch someone staring at you and really out of your field of vision, they are likely to look at you because they felt it she look at she. Or they farted quietly. You have other senses.
