An object that proves the adventure the main characters had written off as All Just a Dream was not a dream after all. Usually something relatively small and conspicuous, which may have been a MacGuffin at a previous stage of the story. It's found shortly after the protagonist "wakes up", and usually right after they begin to question the reality of their experience. It may be used in The Stinger. Sometimes it's never found by a character, and is only shown to the audience in a kind of wink from the creator, but this can leave the audience unsatisfied, as it leaves the characters believing that their entire adventure never happened.
This can be played with elements of ambiguity. Sometimes the keepsake is definitely from the dreamworld and even has supernatural powers; at other times, it's a relatively mundane trinket whose presence is at best somewhat implausible, and which may have alternate explanations. Worse, finding an item from a dream can lead a character to question the reality of their waking life.
This plot device isn't only employed in dream sequences. Many a protagonist has returned from the Magical Land with a souvenir, sometimes a powerful one that will give them an edge in their ordinary life. This way, the audience is assured that they won't languish in mundanity from now on. At the least, the item can be used to quell people who doubt the protagonist's story, though few will be really convinced.

- Ziz-zagged in Romancing Saga 3. When Muse, an already ill-in-bed lady, is poisoned by Jackal with a potion (maliciously claiming to be medicine) that causes her to be trapped in a dream dungeon. From the outside, she looks alive, but unconscious of the world around her and struggling. Sharl, a dear friend of Muse (with one missing hand) who was trying to nurse her back to health suggests drinking it so he can try to help. The player has the option to join Sharl in his attempt to help Muse. (Refusing causes him to drink the potion alone, and both Sharl and Muse become permanently removed as players for the rest of the game, effectively dead.) The resulting dungeon has random encounters significantly more powerful than normal, and the boss of the dungeon is effectively That One Boss. However, the dungeon has a few items in it, two notable. The Dream Tears, a powerful consumable that heals all health and mana when used in combat (although doesn't cure LP, the stat that limits how many times you can be revived), and the Silver Hand, a Gamebreaker equipment that lets Sharl attacks as normal (with boosted stats), or lets other units normal attack twice in a turn. Defeating the one-time dungeon cures Muse and causes the Dream Tears to disappear from your inventory since they are a figment of the dream. However, the Silver Hand is explictively noted in surprise that it does NOT disappear, representing the bond and gratitude of Muse toward Sharl and her desire to help him. The two then become available as party members.

He is surprised to find that he still has the ring when he wakes up. Items can also be brought into the Dream Bubbles too, and using this both ways allows Aranea to Mind-control Gamzee into sleeping and bringing her the ring so she can bring herself to life with it, then waking him up while touching him so she will be transported to where he was sleeping.
- Part of the Running Gag in Housepets! where encounters with the "Celestial Nerds" end with an All Just a Dream situation that is almost immediately subverted.

- xkcd. This deconstruction of a Summon Everyman Hero fantasy — the protagonist has a thank-you gift which proves to him, but wouldn't prove to anyone else, that his adventures in another world were real.

Amusingly enough, in the second season, passenger Jesse Cosay meets Tulip's reflection on the train and ultimately manages to take her off with him, making her technically his Fantasy Keepsake.
