I think that's one of the reason. Idk if the "hatred" towards the biological father plays a role on it too or not.
But yes.Their souls are not in the "right place", they are both in a wrong body, in a world they're not supposed to be. So the people around both of them unconsciously felt uncomfortable and disturbed by their existence alone. They will hate both Camilla and OG Camilla without even knowing why. That's why, now that they have switched back to the place they're supposed to belong, everyone is nice to Camilla again, because the uncomfortable feeling has gone away.
I feel so bad for the other Camilla. Being hated by even your mother for simply existing in a world you weren't meant to be in is so cruel. Was it ever revealed how she is doing right now? Did she die or is she alive in her og world?
