To lazily point to a Wikipedia article to explain my choice of words in the title of this collection... in sociology, "Passing is the ability of a person to be regarded as a member of an identity group or category, such as racial identity, ethnicity, caste, social class, sexual orientation, gender, religion, age and/or disability status, that is often different from their own."
These games, stories, and other creations are about nonhumans who pass as, disguise themselves as, or are taken for humans.
If the story focuses on the discomfort of trying to fit in, it can be a metaphor what it feels like to pass as one of the groups listed in the sociological definition. Using a nonhuman fantasy metaphor instead of a literal real-world marginalized group helps the audience imagine themselves in a different role than their own and think for themselves about how the story might be similar to various real-world groups.
If the story focuses on how strange human life can seem when viewed from a nonhuman's perspective, then it can help the audience to see things that they take for granted in their daily lives. Making the familiar feel strange is a narrative device called defamiliarization.
In some cases, these stories can be about literally feeling as though you are a foreigner to human society.

Content: Rated G.
Medium: A tabletop role-playing game (TTRPG) with a single page of rules for 2-10 players, plus a game master. Each of you will play one of the animals in the coat as you cooperate. (Alternatively, you split into two or more teams, and compete against each other.) Depending on where you are in the stack, you have different responsibilities. For example, the animals on top do the talking, and the animals in the middle operate the hands.
Story: You are one animal in a stack of animals in a coat. Do everyday errands or jobs without anyone discovering that that's what you are. I love this game's tagline, "What is a (hu)man... but a miserable pile of animals?"

Medium: A computer game.
Accessibility notes: In the options, you can turn off screen shake and background animation.
Story: You are a coat full of rats. When you talk to your human friends, make sure you say the right things that won't make them upset... which can only be learned through trial and error, and is unique to each of your human friends. Each time you mess up, you have to do more to hold yourself together.
Metaphor: This is meant to be about social anxiety. It conveys that talking with your friends can feel like a high-stakes puzzle that you can never master.
Vibe: similar to the sense of comedic but genuine tension that you get when you're supposed to play each verse of a song faster and faster without making any mistakes.
Content: Rated PG.

If you could lose all memory of being a bird, then you will be stuck as a human, wandering the world with a feeling that you don't belong.
Metaphor: The game designer doesn't say what real-world situation they intended the human-passing themes to represent. I get the impression that the focus is on self-sacrifice in pursuit of a larger cause.

Medium: A solo journaling tabletop roleplaying game (TTRPG).
About: You play a changeling as their loved ones find out that they are secretly a fairy.

Metaphor: The game developers talked about how interesting it was to them that players related to the human-passing themes as a metaphor for a variety of real-world situations. For example, impostor syndrome, various disabilities, and being in the closet about being LGBTQIA.
