Martians. They're everywhere. In your closet. Under your bed. Everywhere. They can't actually touch you, any more than you can touch them; what they can do is blat out your secrets.

Of course not! And that is the invaders' Plan: to turn us into a bunch of lunatics, and then steal our planet. Only one person knows how to neutralize the Martians.
