ELI5: What am I feeling when someone puts a finger close to my forehead, over my "third eye"?

Edit: I am referring to the feeling you get when someone hovers a finger over your nose and more or less between the eyes when they're closed (where some people claim our third eye would be). It is as if you could feel the finger is there without it touching you. If you haven't experienced it, you should try it!

A change in heat, light (even with your eyes closed you can detect changes in light), and ambient sound (stereo hearing can detect objects, try standing one inch from a wall). So many senses besides your eyes work together to help you "see".
