A character is being fooled by an illusion, but for reasons that may vary (like A Glitch in the Matrix or newfound self-confidence), the illusion is finally destroyed. Said illusion could be the work of a Shapeshifter, a Lotus-Eater Machine, or The Final Temptation.
A common consequence of Spotting the Thread. Compare A Glitch in the Matrix, in which the illusion isn't necessarily destroyed. See also Shapeshifter Guilt Trip. A Glamour is often dispelled this way, causing Glamour Failure. See also Epiphanic Prison, in which Shattering the Illusion allows the character to learn something.
As a reveal trope, consider this a Spoiler Warning!
- Happens in Hellsing (manga and OVA) when Seras is able to shatter Zorin Blitz's illusion/Mind Rape powers. This is shortly followed by what is hands down Seras' Moment of Awesome.
- In Magical Girl Lyrical Nanoha A's, the Book of Darkness traps Fate inside a Lotus-Eater Machine but Fate soon realizes that this reality is way too good for her and shatters it. In process, it is revealed that she had a special illusion-breaking spell ready for just such occasion.
- Happens in Pokémon if Zoroark is damaged while using the move Illusion.
- Happens in Naruto whenever anyone has to break an opponent's genjutsu.
- Saiyuki Reload combines this with a non-lethal case of Hoist by His Own Petard. Sanzo, Gojyo and Hakkai are hypnotized by Zakuro, a demon illusionist recruited to get rid of them. Even though the three are aware that they're merely trapped in an illusion, Zakuro's powers are strong enough to manipulate their senses anyway, countering any attempt to break out. When part of Kougaiji's group catches up with them, Dokugakuji proceeds to rescue Gojyo by knocking him out. Sanzo and Hakkai decide that this is not an option for them, as being unconscious would only leave them defenseless, but Zakuro's next illusion makes them appear submerged in water and unable to breathe. Hakkai "drowns" and faints, but for Sanzo, who was found in a river as a baby, the illusion triggers a memory of his master and father figure, Koumyou, which proves enough to make him immune to Zakuro's tricks.
Sanzo: "Wrong choice of image. What I saw was... light."
- Magic: The Gathering
- Gerrard does a FaceHeel Turn in order to win Hanna back from the dead. As he's going to give her Urza's head, however, he suddenly realizes she's nothing but an illusion created by Yawgmoth. He shatters the illusion by slaying the fake Hanna.

- Happens literally in the Star Trek: The Next Generation episode "Frame of Mind", in which Riker realises he's actually a prisoner in a virtual reality, and the illusion literally shatters like chunks of glass.
- An episode of How I Met Your Mother had a comedy variant of this, in which the characters started pointing out each other's flaws. Each "revelation" was accompanied by a sound of glass shattering as the "illusion" was shattered. Also, the episode tag had the illusion of a deaf person shatter by literally putting onscreen "Glass Shattering" in subtitles.
- House: season 2 finale has House realizing that nearly everything thus far in the episode has been a hallucination. He is only able to shatter the illusion by using a surgery robot to slice his Patient of the Week open lengthwise... and even then there's an agonizing few moments where he isn't sure there was an illusion in the first place.
- The Twilight Zone (1959): In "The Arrival", Grant Sheckly's theory that Flight 107, which arrived without any crew or passengers, is nothing more than an illusion is proven when he puts his arm in the spinning propeller and the plane vanishes. His fellow investigators Bengston and Paul Malloy disappear as well.
- Lindsey Stirling's "Transcendence" music video is themed around her discovering that the projected clothes, backgrounds, places, and so on are not real.

- In Shin Megami Tensei III: Nocturne, you do a rather physical form of this: the oni demon Ongyo-Ki summons three illusory copies of himself to fight. Sock the right one and all three copies will be reduced to dust. The catch is that if you attempt to use any move that hits more than one of the oni, it will fail and it will count as a missed attack. Given a missed attack means a loss of two Press Turns, he can easily destroy you unless you know how to suss out the real one. How do you know the real one? When fought on the full moon, only the real one has a shadow.
- In The Legend of Heroes: Trails in the Sky SC, the heroine is trapped in a dream by Luciola the Bewitching Bell.
