Is there a scientific explanation for how we can feel someone staring at us?
I can easily see how this would be some kind of built-in survival instinct, but has there been any successful research to explain how it works? For example, what part of the brain is responsible for alerting us that someone is staring at us, and how it gets the input to know this?
