When normal objects are arranged in a manner that resembles a monster.
A character (usually a child) has heard a Ghost Story and is frightened that the monster described in said story will come for them. Later (always at night), during a thunderstorm, that character will see what is undoubtedly the shadow of the monster!... only it turns out to be several normal objects arranged so that it vaguely resembles the monster. How they got that way, we'll never know.
Truth in Television to some extent. Impossible Shadow Puppets are often involved. See also Big Shadow, Little Creature, Poorly Lit Pareidolia, Shock-and-Switch Ending. Contrast Shadow Discretion Shot. Compare Bait-and-Switch Silhouette (a similar gag with silhouettes instead of shadows) and Coincidental Accidental Disguise. May be used for a Pseudo-Crisis Cliffhanger.

- Of course, many Real Life people have experienced this at some point or another. In Real Life, this is an example of pareidolia, seeing or hearing patterns or significance in what amounts to the random noise of the world. The most famous example would be the face on Mars, which combines coincidental shadows (the eyes) and a square of missing data (the nose) to construct a human face. Later, better photographs eliminated the illusion completely.
