Come to Think of It, Who Are You?

At 3:17 in the morning, the self in the mirror spoke. "Remember who you are." But I'm standing here - who is that in the mirror? --- My cat is missing. It's not that I got lost, it's that everyone said that I had never had a cat. I looked through my phone and couldn't find a single photo of it. I asked my friends and no one remembered it existed. Only I remember - it's called Nian Gao, it's white, it has different eyes, and it jumps on the bed every morning to step on its breasts. Then I discovered, it wasn't just cats. My colleagues started not being able to pronounce my name. HR said that the person "Lin Shen" could not be found in the social security system. I took out my ID card - the photo on it was slowly blurring. My mother called and suddenly stopped talking: "You... What's your name?" I am disappearing from this world. Not death, not disappearance - being forgotten. Like it never existed.
