You ever get the feeling you're being watched?

Your every move, monitored from afar by some unseen source... and you can feel it?

You ever sit alone in a room, and then have this sudden urge to look behind you, as if you'll catch sight of something that shouldn't be?

It's not uncommon. Many people have admitted to feeling something "in the air"... something either curious or malicious, depending on who you talk to.

It's this same type of feeling one gets during a very suspenseful scene in a movie, where you're absolutely sure that something terrible is going to happen but you're frozen in place, waiting for the outcome. And when it comes, you leap in fright not because the image itself was anything all that scary, but because your mind prepped you into a state of extreme caution by pumping you full of adrenaline in the case of a real emergency.

Or, you know... you just could be nuts.

Delusional, even.

Maybe you should see a doctor...
