A subversion of the most fundamental aspect of Dialogue: whether a character is talking to someone else or not. Commonly, a character will appear to be making a brave confession, and then be revealed to have just been practicing before a mirror. Or, he will seem to be explaining his life to someone, and then be shown to be talking to a gravestone. Visual media typically use a Reveal Shot, often a Closeup on Head, to execute Trick Dialogue. Compare Fourth Wall Psych (where the character appears to be speaking to the audience but is actually talking to another person). See also Not So Dire.
