Is my sister a narcissist or is she just toxic? How do I deal with her?

So for context my sister is 25 and I'm 20(F). In my culture, we live with our parents till we get married and so we both share a room and always have.

So in the past when I was young (early teens) she would basically control everything in the room and she would decide when we would talk or have fun and when it's time for her to be mean.

As we grew up she got worse, her mood swings are intense and she would suddenly shut me out mid conversation (like literally just stops talking to me) for no reason, and whenever it's time for me to talk she either doesn't like whatever I'm saying,or she would either just say I'm tired let's stop talking or even gaslight me into thinking I'm boring even though when she talks it's all about her and how people are mean to her and somehow jealous of her.Oh right, she sometimes thinks I'm jealous of her and mentions it as a joke but repeatedly when I say I don't like the picture she took of herself or like a new makeup look? Even though she hates on every picture I take of myself to the point where I don't anymore.

She also doesn't let me decorate my side of the room the way I want, she says I have bad taste. Also, all my makeup and stuff is in the drawers while her stuff is on the vanity all nice and perfect, and when I tell her about it she says that my stuff just doesn't look nice?

Also, whenever she goes to work before I wake up she doesn't respect the fact that I'm sleeping and opens the curtains halfway and turns on the light and watches her show, even though I clearly talked to her about it a thousand times. She also forces me out of the room because the room is for sleep which is understandable but what is crazy is that it's for staying up all night when she doesn't want to sleep? So in both cases I leave the room. I do argue with her about it but it just ends up with her disturbing my sleep if I stay.

She always turns on me whenever there's any issue in her life , I'm kind of her punching bag. She also likes to make fun of me in a really subtle way you feel like it's mean but you're not sure and the funny thing is that she calls out people who are mean to her and cursing them and all but she does it to me??However, she is sometimes nice when everything goes her way so she's not that bad of a person.

For context, she doesn't click with anyone in the family but the thing is none of them share a room with her so they don't have to deal with her.

Ok, so now my side since I'm obviously not perfect. So tbh my flaw that she uses all the time when I talk about our shared room is that I don't help her clean the bathroom which sounds bad but it isn't.

We have a maid and she cleans everyone's rooms and bathrooms but I respected the fact that my sister wants us to clean the room so I obliged. But about the bathroom she wants to take on more chores then it's on her. I am also a tad bit messy but not in a gross way , I sometimes just leave a few clothes on the side of the bed or like my notebooks on the desk splayed out nothing gross but she likes to use it against me all the time when she herself is really not that tidy.

Lastly, I am not the emotional type and I don't validate her wrong feelings but I feel like that's correct, and whenever I talk to her about something she does that hurts me she'll eaither act like I'm the bad person or just laugh and ignore me.

I learned to block her out but idk am I being dramatic here?
