User blog:MisterRandom2/Do Demons really have telepathy?

Telepathy is listed as a "common ability" under the Demons page. But in the show, we've seen plenty of instances in which Sam and Dean have lied to demons and gotten away with it. In fact, barring Phantom Traveler in which Dean just speculates that the demon read Sam's mind to learn about Jessica, I can't recall an instance where a demon has been able to read someone's mind.
