"Because," said Scrooge, "a little thing affects them. A slight disorder of the stomach makes them cheats. You may be an undigested bit of beef, a blot of mustard, a crumb of cheese, a fragment of an underdone potato. There's more of gravy than of grave about you, whatever you are!"
In media, eating food can give a character nightmares. Whether it's because the food was eaten in excess or there's something special about the food in all, the character will suffer from bad dreams — sometimes featuring the food somehow.
It's also common for characters deep in denial to Discuss this trope in order to reject the idea that some obvious symbolism in their dream (for example, a Homoerotic or Recurring Dream) actually means anything, or (as with Scrooge in the page quote) that something fantastical is actually happening in real life.
A variant of the Mushroom Samba commonly found in sitcoms and cartoons. Humor using this trope is often combined with No More for Me, as the dreamer doesn't want it to happen again. Despite the superficially similar name, probably won't take you to an Acid-Trip Dimension — different kind of acid, for one thing. Not to be confused with Nutritional Nightmare. Compare Death by Gluttony, The Food Poisoning Incident, and Food Coma for other bad things that can happen to characters who eat too much.
- In this commercial for California Raisins, a Claymation version of Michael Jackson blames his weird dream on something he ate.
- In a commercial for the Seattle Mariners baseball team, after the Mariner Moose had a nightmare about being replaced by a latte mascot, Jamie Moyer blames it on the nachos he ate before bed.

- Averted in Yu-Gi-Oh! The Movie: Pyramid of Light. When Pegasus wakes up from a nightmare involving the Egyptian God Cards, he at first blames it on the wine spritzer he had before going to bed. But he quickly realizes it probably had a deeper meaning.
- Invoked in Alan Ford: in the volume On the Track of Melissa, the titular criminal is still at large after two whole volumes of hunt, and no one can figure out their identity.

He does have two vivid dreams (one of which is a parody of Little Red Riding Hood) and obtains some faint clues which eventually help him resolve the case.
- Jokingly referenced in Cerebus the Aardvark rather than used. In Guys, Cerebus has an alcohol-induced nightmare involving Roaring Rick Veitch and his Rare-Bit Fiends. This is a parody of Veitch's actual comic/dream journal Roarin' Rick's Rare Bit Fiends, which was based off Winsor McCay's comic strip Dream of the Rarebit Fiend, whose title referenced the notion that eating too much Welsh rarebit would cause nightmares.
- In the Scrooge McDuck comic The Dream of a Lifetime by Don Rosa, the Beagle Boys invade Scrooge's dreams to steal the door combinations to his money bin's vault. When the dreams (all recollections from Scrooge's adventurous past) get too wild for them they pin it down to pre-bedtime meals.
- The Fabulous Furry Freak Brothers had a story where the trio breaks into a prison to free a friend. There's lots of high-body-count mayhem, and when Fat Freddy gets swarmed and beaten by hundreds of police, we see he's dreaming and his two friends are angrily swatting him with a rolled-up newspaper for eating all two dozen hashish-laced cookies they'd baked for a party. Then, in a much much later story, the wake-up scene is repeated, implying everything that happened in that 12-year span was him dreaming!
- Father Christmas: In "Father Christmas Goes on Holiday", Father Christmas gets food poisoning after eating too much cream. The first symptom is that he dreams about his food dancing, accompanied by a cow who vomits up cream.
- This actually drives part of the plot in Gene Luen Yang's Loyola Chin and the San Peligran Order. The title character starts experimenting with the sorts of dreams she gets from eating odd combinations of foods, which leads to her encounter with Saint Danger of the titular San Peligran Order.
- One issue of the Roger Rabbit comic book had some bad rhubarb pie causing Roger to dream of a Bad Future where he failed to renew his contract with Maroon Cartoons. Among other things that had gone wrong, Jessica had gone to seed after having to get a second job as a soda jerk, a lot of his Toon friends were struggling to find work, and Roger himself was stuck as the sidekick to an obnoxious kids' show host.
- In an early Sonic the Hedgehog (Archie Comics) issue, Sonic chows down on one too many chili dogs and dreams he's "Sonic the Chili Dog", his fellow Freedom Fighters are condiments, and Robotnik was a hamburger.

- One issue of the Mirage Teenage Mutant Ninja Turtles comic, done by guest artist Matt Howarth, features all the Turtles and Splinter having odd dreams but only Donatello's count as an Acid Reflux Nightmare. After eating an entire bag of chocolate chip cheese cookies, he falls asleep and dreams he and his brothers and captured by the Feds and are subjected to nefarious tests and tortures. Meanwhile, a government file regarding them is stolen and sold to a Hollywood director, who exploits it for his own gain via cartoons and toys (A not so subtle Take That! to the original cartoonnote ). Eventually, the Turtles become prisoners of their own fame and lay around watching TV all day getting lazy and fat. Don then wakes up screaming "Teenage Couch Potato Turtles!"
- Beetle Bailey:
- In one strip, Sarge is dreaming about eating a bowl of things that look like Beetle's face smiling at him. He wakes up and swears to never put baby peppercorns on his pizza again.
- In another Sunday strip, Sarge falls asleep after watching football all day, and dreams he's a star quarterback at the Soup Bowl, paid with food by his team, able to throw off the opposition by burping, rewarded with a chocolate football when his team leads at the half (one with almonds when they win the game) and in contention for the world record for hot dog eating. He wakes up, and says "I have that same dream every time I fall asleep with my hand in the popcorn..."
- Subverted in the Blondie strip seen here where Dagwood has great dreams after having a pizza with triple anchovies before bed.
- This Dennis the Menace (US) strip from 2012.
- This◊ Dogs of C-Kennel strip had Will dream that Kenny is a snake who swallows him in one gulp, before he wakes up saying, "Remind me to never again scarf down ten chili dogs before bed."
- Winsor McCay's Dream of the Rarebit Fiend was an entire newspaper strip about nothing but Acid Reflux Nightmares. Rarebit, (or rabbit) incidentally, is spicy cheese sauce spread on toast; there's a folkloric link between eating cheese before going to bed and nightmares.
- The strip was adapted into possibly the first Live-Action Adaptation ever, 1906 film Dream of a Rarebit Fiend.
- McCay's strip would later be the inspiration for Rick Veitch's comic book/dream journal Roarin' Rick's Rare Bit Fiends, which in turn was parodied in Cerebus the Aardvark.

One Sunday strip has an odd Inversion (the dream gives him heartburn) where he dreams he gets the world's largest cookie, then the largest box of sardines, largest loaf of garlic bread, and largest bowl of five-alarm chili; he wakes up, and needs the world's largest antacid pill.
- In the Luann strip seen here, Luann has a dream that involves King Kong, an elf, a school bus, balloons with Quill's face, and herself as Darth Vader; her New Age friend Dez is trying to interpret it, but Bernice simply thinks it's due to eating flaming hot nachos before bed.
- This strip from 1965. Snoopy has a nightmare in which Charlie Brown flies him like a kite and he breaks into pieces upon landing. When he wakes up, he thinks it's because of the pizza he ate before bed.

- In Lucy Maud Montgomery's The Story Girl, the aimless child heroes of the narrative decide to record their dreams for a summer, and begin to deliberately eat rich food before going to bed so that they dream as vividly and crazily as possible.

- After Jonny 2x4 wakes up in the Dream Within a Dream ending of the episode "Rock-A-Bye Ed", he decides "No more free-range soybeans before bed."
- "A Glass of Warm Ed" featured Ed sleepwalking hilarious distances through the neighborhood. While it is uncertain if eating before bed caused this, as he sleepwalks Ed eats virtually everything in his path, from regular foods to Edd's cactus to Jimmy (who is thrown up later).
- While it didn't really happen while he was asleep, in the Halloween special "Ed, Edd n Eddy's Boo Haw Haw", due to a combination of junk food and too many horror movies, Ed's already loose grip on reality becomes even more unhinged, resulting in him mistaking every kid in the neighborhood for monsters and viciously attacking them.

- Also referenced in "Dueling Eds", which opens with a kung fu school scam, where Eddy uses a mirror trick to make it look like he's created copies of himself. Of course, Jonny was awake at the time, but still.

He wakes up and refuses to eat a plate of lasagna. Then eats it anyway.
- Similarly, in the children's book "Garfield's Cat Nap", Garfield eats a slice of pizza as a midnight snack to indulge himself after being given only a salad for dinner.

Kind of a subversion of the above example, in that when Garfield wakes up, he's thankful for all the normal food he can eat.
- In The Grim Adventures of Billy & Mandy, Billy feeds himself, Grim and Mandy rotted pizza. Hilarity ensues in their respective dreams.
- It was sort of subverted with Mandy's dream, a parody of the A Night on Bald Mountain sequence from Fantasia, as she was in place of Chernabog. It probably would have been a nightmare for anyone but Mandy. (When she wakes up, she even eats the last piece of the pizza.)
- A third example, though not happening in a nightmare, involves Billy and Grim turning into each other after they switch roles for the day. When Mandy sees the results, she just goes "I need to stop drinking steak sauce..." and walks off.

- Also in the episode where Homer eats Police Chief Wiggum's "Guatemalan insanity pepper" chili. A bit hazy on the borderline between "nightmare" and "hallucination", but Homer does wake up at the end of his trippy journey through his subconscious (featuring Johnny Cash as the voice of his spirit advisor).
- In The Smurfs: A Christmas Carol , Grouchy tells the Smurf of Christmas Past that she's a figment of his indigestion.

- Apples are said by some people to have an effect similar to that of Welsh rarebit if eaten too close to bedtime.
- A commonly cited anecdote is that eating cheese close to going to bed will give a person particularly vivid dreams, including nightmares.
- It's commonly claimed that Salvador Dalí ate Camembert cheese before sleeping to intentionally invoke this effect, to inspire future paintings.
- An Irish Young Scientist Exhibition stand once concluded that eating cheese before bed did cause nightmares, even though the students behind the stand were skeptical of the saying from the outset.
- As discussed on QI, cheese purportedly gives one good dreams, or at least a good night's sleep, due to its concentration of milk's tryptophan content. Tryptophan is the amino acid that is associated with the myth of causing sleepiness after Thanksgiving dinner, as it's a major component of serotonin, the feel-good neurotransmitter of the year. In the interest of full disclosure, the study in which this was discovered was sponsored by the British Cheese Board.
- Notably, feeling sleepy after eating a big roast meal isn't necessarily because of the tryptophan, because in order for the body to gain access to it, it has to start digesting the protein in the meat. Rather, sleepiness and a lack of concentration after eating is because of the brain engaging the parasympathetic nervous system, the part of the nervous system that revolves around "Rest and Digest" activity, and also by sending more blood to the digestive system organs so they can get to work accessing and processing all the goodies inside your latest meal. With most of the nervous system focused on getting those valuable nutrients out of the food, especially with the sheer amount consumed, the brain has enough blood to function normally but isn't exactly in the right state to be especially alert.
- In the Middle Ages, rye bread was often contaminated with the ergot fungus. Eating this before going to sleep is similar to going to sleep after taking LSDnote and can cause some fairly horrific nightmares.
- Really, eating ergot-contaminated bread at any time is going to mess you up.
- The Salem Witch Trials were thought by some historians to have been brought on in part by grain contaminated by ergot.
- If you actually suffer from acid reflux and get it while you're sleeping (which is pretty much inevitable), you may have strange dreams based on the pain and nausea before finally waking up.
- This can be worsened if you’ve consumed anything doused in Blazing Inferno Hellfire Sauce or even mild hot sauce, as spicy food doesn’t play nice with acid reflux sufferers.
- Even if you have bad or strange dreams no more often than usual, sleeping poorly thanks to indigestion could make you more likely to remember them.
- Food poisoning is often reported to give people strange dreams or nightmares.
