ELI5: Say, someone is staring at us and we haven't seen them yet. Somehow, we figure out that they are staring at us and we instinctively look towards them. How does that happen?

My 10 year old daughter asked me this today. Thought it was an interesting observation to which I didn't have a good answer. Can Reddit's wisdom help? Thanks.

You don't remember all the times you turned around and nobody was staring at you.  Your brain doesn't bother remembering all the times nothing happened, so we have a tendency to think certain random events happen more frequently than they really do.
