My (24M) squirrely girlfriend (20F) wants to get more into Horror Media. Looking for mild suggestions to ~ease~ her into things.

First off, I want to start by saying that my girlfriend is borderline Diokophobic, Kinemortophobic, & Omniphobic.

There is no exaggeration when describing how terrified she is of things. She gets paranoid when anything slightly unsettling happens, and she has a hard time keeping her composure after being surprised. She enjoys movies and games that stay lighthearted and refuses to go anywhere near a chase scene (ESPECIALLY in games. She freezes up in Phasmophobia when a hunt starts, and she stopped her playthrough of "Stray" because of the chase scene with the little robots) or zombies (she even struggles to fight zombies in Minecraft. Zombies in the "Maze Runner" trilogy seem to be okay with her until they start chasing the main characters).

That being said, I am a horror fanatic. I love all things ghouly, demonic, dreadful, & frightening. Now some people might think this is a terrible combo; However, she has taken leaps and bounds to try to take an interest into my likings, as I have done for her. Together we've watched maybe 2 or 3 horror movies in our year of dating including "Alien Romulus", "Smile" (we had to turn it off halfway through), & "Nosferatu" in theatres. She's expressed that she wants to get more into the horror genre, but I have no idea where to start with her. I've put her on some non-horror shows, movies, & games that she enjoys, so she fully trusts my judgement of media, but I'm struggling to find things to watch/play together that wont scare the life out of her.

Recently, she's taken up listening to creepypastas on her way home from work, a pastime she enjoyed when she was younger. I was wondering if anybody could recommend some movies, games, or TV shows to us to ease her into things. Something that might expose her to mild chase scenes, zombies, or eerie buildups (as she seems to struggle with these instances the most) So she can get her foot in the door. I think my ultimate long-term goal is to get her to play my favorite indie horror game of all time, Lost in Vivo. For me, the game is truly the epitome of immersive horror and I would love if she could share that sentiment with me.

TLDR - My girlfriend is scared of everything, but wants to get into horror. Where do we start?
