Crashing Dreams

A character is dreaming; they may or may not realize that they are doing so. For once, it is a dream that makes sense, but then there is a sudden non sequitur. The character does a double take and awakens to find the non sequitur reflects what's really happening around them.

Sometimes it's not a non sequitur and makes sense in both the dream and the real world. Or the two things are distinctly connected but not the same exact thing. Common examples include the person's name being repeated over and over again (a person in the real world calling them); a phone call in dream (which turns out to be an alarm clock); and a passionate kiss, (which turns out to be either an animal licking their face or an unappealing friend giving them the Kiss of Life).

This is also fairly common in Real Life, so it's not too surprising that it's seen cutting a dream short in fiction.

Anime and Manga

 * In Azumanga Daioh, Kaorin imagines being rescued by Sakaki and telling her to call her by her real name. Sakaki beings to say "Kaori... Kaori..."—but then Kaorin wakes up and realizes that it's her mother is calling her. Frustrated, Kaorin throws the sheet over her head and yells "Bring it back!"
 * An Eyecatch in Magical Girl Lyrical Nanoha featured a scene of Nanoha happily munching on a boiled yam, which then cut to a sleeping Nanoha biting into a now very distressed Yuuno.
 * Akane from Ranma ½ was trapped in a sleeping curse. In her dream, she saw a mosquito and started trying to swat it down... In reality, Ranma had lit a mosquito repellent beside her in order to free her from the curse.
 * In Chrono Crusade, Chrono has a dream where Aion is calling out to him to rejoin him while holding out his hand. Chrono almost takes it, but is stopped by a ghostly-looking woman wrapping her arms around him. He wonders aloud in the dream who the warmth is, and begins to say it's "Mar..." before he wakes up and see Rosette looking down at him—who could tell he was having a nightmare and moved his head onto her lap.
 * The second chapter of Mahou Sensei Negima began with Takamachi declaring to Asuna that he loves her and pulling her in for a kiss. Naturally, this turned out to be a dream, and Asuna found herself kissing a Negi that had crawled into her bed when she woke up.
 * The Girl Who Leapt Through Time: The opening scene displays Makoto playing baseball with her friends, when she hears a voice calling her and an alarm clock falls on her head. Then she wakes up.
 * In To Love Ru, Rito is dreaming of something having to do with a marshmallow while groping his younger sister. While she is part of his Unwanted Harem, it makes her uncomfortable and she tries to wake him up by pinching his cheek. He does stop groping her, whining that the marshmallow bit him, but staying asleep.
 * Chapter 32 of Poor Poor Lips begins with Nako dreaming about lots of meat buns. When she tries to bite into one though, it turns out that they were firmer than expected. Then she wakes up and realizes that she was giving Ren a Boob Bite.

Film

 * In The Mask Stanley is having a (PG-13 rated) Erotic Dream of Tina. Tina starts licking his ear aggressively, and Stanley awakens to find his dog Milo licking him.
 * In Bruce Almighty Bruce is having another conversation with God when God abruptly pokes him painfully in the chest. Bruce awakens to discover he's being defibrillated back to life by the hospital staff.
 * From surrounded by lovely ladies, to playful biting, to waking up and getting half-eaten by vultures in Shanghai Noon.
 * And again in Shanghai Knights—the same character dreams of the girl he likes making out with him, then wakes up surrounded by sheep.
 * Near the start of The Matrix, in the club, the Music turns into an alarm clock sound before Neo wakes up.
 * I don't think they did this to imply that he was dreaming the scene in the club, that scene actually happened. The music changing into the sound of the alarm clock and Neo waking up was just a transition.
 * Of course, it might be accurate to say that Neo WAS dreaming (at least in the sense that his entire life is a dream), though it's not really an example of this trope.
 * When watching the movie, the transition appears to be a way to suggest the All Just a Dream possibility to the audience, setting up a somewhat mysterious atmosphere.
 * In The Lord of the Rings Aragorn and Arwen kiss, and he wakes up to his horse nuzzling him awake.
 * The opening sequence in Kung Fu Panda is revealed as a dream when Monkey and Tigress of the Furious Five start telling Po that he'll be late for work in his father's voice.

 * In the Disney version of Alice in Wonderland, Alice shouts at herself through the keyhole of the talking door to wake up, and her voice dissolves into the voice of her older sister calling to her.
 * In Dumb and Dumber, a character falls asleep while driving. The headlights of an oncoming truck cause a breast-related non-sequitur that ruins his Erotic Dream, and wakes him up Just in Time.
 * Pee Wee's Big Adventure - Pee-Wee easily wins the Tour de France in his big coaster bike, in his gray suit - a crowd is gathered to watch him get crowned, an alarm bell sounds, everyone runs off, he stands there waiting, eyes shut, giddy with anticipation - then wakes up to the sound of his alarm clock.
 * Similar to the Mask example above, in Harold and Kumar Go To White Castle, Harold falls unconscious and dreams of his love interest licking his cheek. Instead of an animal, he awakens to find Kumar licking him because Kumar "thought doing some gay shit might wake him up."
 * Inception has a wild variation of this; in any dream level above the one any of the characters are currently in, things that happen to their body affect various things in the dream level below. It goes all out, too; areas flood/experience severe rainstorms when characters get wet, the rules of gravity start changing, They even use specially tailored sedatives to a allow specific sensations to penetrate between levels of the dreams.
 * In the first act of Girl, Interrupted, the main character has just checked into a psychiatric hospital. Her flashback daydreams are routinely interrupted by a nurse's "checks".

Events that happen to the unconscious Earl affect the world inside Earl's mind: for example, Catalina reading gossip magazines to Earl results in random appearances by Paris Hilton.
 * Lost has used the "someone saying the character's name" trick to pull characters out of both dreams and flashbacks. Once Hurley appeared dressed as John the Baptist in Charlie's religious dream, because Hurley was actually speaking to Charlie outside the dream.

He realizes he is dreaming when Edmund turns round and sees his auntie has turned up and Baldrick now has the head of an Alsatian.
 * At the beginning of the Young Ones episode "Time", Neil dreams that he is the head of a Texas oil company, giving away oil wells tax-free and randomly throwing money out of his office window.

And then its tongue becomes Opalescence (Rarity's cat), causing her to fall. And promptly wake up.
