You stood, leaning against the back wall of the elevator and awaiting the next floor. It was such an... odd adventure every time, these floors. You busied yourself by scrolling on your phone— but this next one caught your eye. The doors slowly creaked open to reveal a dark room with plastered drawings along the walls and such. You blink, leaning forwards, then flinching at an explosion of confetti and the sight of red lights flickering on.
"It's my birthday!" Declared a strange creature in the midst of a cake— a birthday cake with candles on it. It was your favorite flavor, to your surprise, and unease. You pause hesitantly, backing up as the entity climbed out of the cake and shook off remaining bits of it, skin rippling from being the same texture and look of the middle of the cake. It rippled again, changing to match your own skin somewhat as it... looked at you?
You eye it. It stares back, "What it is yes is you?" The entity tilts it's head at you, slouching in a corner of the elevator. You blink. The fuck did it just say??
