Dungeons and Tombs in Modern AC Games Make Me Squeamish (Literally)

Hello, I'm a long time AC fan. Been playing since AC1. I was a huge fan of tombs and catacombs in different AC games but since Origins, every tomb-like setting makes me, well, literally puke. I'm so confused.

Take my current AC Shadows playthrough. I got stuck in a Kofun and was trying to navigate out when all of a sudden I start feeling dizzy and then feel like I need to rush to the washroom to puke. And I did. It was absurd.

I'm no stranger to tombs in video games. I've played the Tomb Raider trilogy as well without any issues but I am convinced it's the new AC games.

Does anyone else feel or experience this? I'm so confused.
