The characters are stumbling through a desert, for whatever reason. They're unprepared, dehydrated and starving, desperate, depressed, generally in a sorry way.
But hark! One of the characters sees an oasis. Glittering blue water, cool palm trees, a small carpet of grass growing around it, and in some cases, beckoning Bedlah Babes. They sprint to it and fill their mouths with handfuls of refreshing water... and then the scene fades, leaving the characters to spit out their mouthfuls of gritty sand. Some examples forgo the oasis altogether, resulting in a phenomenon similar to Meat-O-Vision where characters hallucinate bars, ice cream stands and water fountains that vanish into thin air when the desperate travelers sprint towards them.
A Real Life mirage is simply an optical illusion wherein it appears that the sky becomes refracted on a hot, flat surface, creating a blue area that looks like water a distance ahead of you; this can happen in several climates (including temperate ones where one sometimes sees puddles of water on a warm blacktop road), but seeing water in the desert has a greater appeal. Only a water-like blue patch appears in a real mirage, however. The palm trees, grass and refreshments that disappear with the water are largely a result of comedic exaggeration. However, the term "mirage" is also used for when someone has a hallucination, leading to this confusion.
- Pepsiman: One commercial features a man stranded in the desert, whom Pepsiman appears to. Only it's a cactus that the man believed was Pepsiman. The Pepsi can at the end of the commercial also disappears.
- Jewelpet: Magical Change: Episode 33's "Jewelpet: Currently on the Run" segment has a thirsty Ruby in a desert running into mirages of not just an oasis, but of things like a store and a water park too.

When Ruby decides to drink the water despite Labra's mind-control attached to it, she discovers Labra is a mirage... and then Ruby herself realizes she's a mirage as well.
- In One Piece, the mirages Nami creates are...interesting to say the least. They properly use the idea of mirages being created by the differences in air density caused by sharp temperature differential, but they have Nami create mirages by standing behind the anomaly, which logically would reflect her image back at herself, not distort it for the enemy to see. It was used correctly the first time, though. Not even going into how she can supposedly control what is seen... A lot of what Nami does in a fight, post Alabasta arc, pretty much can boil down to using her Clima-tact.

Luke is left to console the man after the mirage vanishes, though it's never actually shown to the reader.
- The Adventures of Tintin (2011): Downplayed. Haddock sees the ocean in the desert, but this is partly due to being drunk, and Tintin describes it accurately (as a hallucination, not as a mirage).
- A variant occurs in An American Tail: Fievel Goes West, where Fievel saw his family while stumbling in the desert, but they turned out to be (apparently very small) cactuses.

- In Pleasant Goat and Big Big Wolf: The Tiger Prowess, Lord Japper throws Weslie and Wolffy into the desert, where they try to find a pyramid described by Mr. Slowy as having a special totem that can make them invincible.

- Mario Party 3: Happens in Spiny Desert, somehow. There's a 'mirage' form of the Millennium Star, which only vanishes when someone tries to buy a star from it (and beforehand, makes it appear like there's two of the character on the map). It's probably more accurate to call it a hallucination.
