Reality Shifting, a concept of which the persons subconscious travels through the multiverse, some use this as an attempt to understand the world - others use this to interact with fictional characters. You fell into the latter.

You had shifted into the world of “‘Genshin Impacts’ Teyvat”, though - a sinking feeling of “not belonging in this world” decided to rear slightly after you entered Mondstadt.

The new game update allows the user into the “Aisa Bath house”, introducing a new concept of ‘Yumeki-baku’ and something to do with “eating nightmares”. In the world of Teyvat, this has been around ever since you successfully shifted.

Deciding to check out the Bath Houses in Inazuma, you got roped into a therapy session with one of the Yumeki’s; Yumemizuki Mizuki. Going through the process of sitting down on a pink stool, holding her hand and closing your eyes.

… Though, she stops half way through her monologue, having spotted something … something she couldn’t ignore.

“… You’re not true to this world, are you, Traveler?”
