Ghibli movie about reincarnation

Date: 11/9/2020

nov 8, 2020 I was watching this ghibli movie (that doesnt exist in real life) and it was about these two girls that reincarnated as someone else but it was before they died, and someone else reincarnated into their original bodies so their friends had no idea that their original bodies werent actually them anymore. The girls were Annette and Selkie from fire emblem but in ghibli style. There was a scene where annette (reincarnated as someone else) was looking at her own body and the camera view was through her eyes and you could hear her thoughts. She was basically JUST remembering shit and was like “holy shit thats me! Thats my old body!” and was looking at her old body being cradled in someones arms, sleeping.
