A liar often smiles subtly while telling a lie; it's an unconscious expression of his delight in getting away with a whopper.

Dreams are the expression of the unconscious while we are asleep.

As someone who specializes in deception, I'll tell you this much: When someone insistently implores, 'Believe me,' don't. Pleading 'believe me' or 'trust me' - insisting to people that you are telling the truth - is a tell-tale sign that you probably aren't.

Old liars
hold lies.

For the liespotter who knows how to listen well, the random words, sounds, and phrases in a person's speech are never as random as they seem. They offer a clear sightline into the liar's psyche.

Lying is a cooperative act. Think about it. A lie has no power whatsoever by its mere utterance. Its power emerges when someone else agrees to believe the lie.
