Scopesthesia, also known as the sense of being stared at, is the ability to sense when someone is staring at you without using known sensory cues. Examples of Scopesthesia include: 

• Turning around: You turn around to find someone looking at you. 
• Looking back: You look at someone and they turn around and look back at you. 
• Feeling a tingling: You feel an unpleasant tingling that builds until you turn to look. 

The term scopaesthesia comes from the Greek words scopein, which means “to see”, and aesthesia, which means “feeling”. 

Surveys have found that 77–90% of people have experienced Scopesthesia. Some suggest that humans evolved to be sensitive to other people’s gaze, and that the brain has a neural network dedicated to processing gaze.
