What is this kink? (And does anyone else have it???)

Idk where it came from or why I started feeling this way. But for months I've been having this crazy fantasy. (Trigger warning for kidnapping and dehumanization).

I fantasize about falling in love with someone. And they obsess over me. They always text me, always wanna hang out, always wanna know where I am, and they treat me so well that I don't mind this possessiveness. It gets worse though. I have fantasies about the person earning all my love an trust, that they get to have as much control as they want over every aspect of my life. If they want to dye my hair, I will. If they want me to wear makeup, I will. If they want me to starve until nighttime, I will. If they want me to wear something absurd, I will.

I fantasize about them bringing me to their basement and locking me away. They never let me leave, and there's no windows so I never know how long I'm down there. I can't go out to hang w my friends, I can't work, I can't go outside ever again. They see me as a pet they keep in secret. And even though they're keeping me, they make sure I have whatever I want to keep me happy. Things like a bed, a couch, paper for coloring, etc. But in return, they're in charge of everything. I eat only when they allow me (and I only eat what they allow me to eat. I like to imagine they'd bring me foods I enjoy because they love me, but if I'm bad they'll bring me food I don't like, and I have to eat it or I'll get in trouble). I only do fun stuff when they allow me. Every single thing I do, I only do when they allow me.

Still, I like to imagine decent conditions. I'd never be nearly killed; they'd be very strict and I'd be punished if I were bad but I'd get lots of love after, and for the most part, my lover is still sweet to me. But I belong to them in every shape, way and form. And I can never leave. But why would I ever want to?

I honestly feel like kind of a bad person for these fantasies, cuz real life kidnapping is not something to fetishize. It's actually one of my biggest fears. But I don't know why I think about this so much
