What does Jodie mean with this sentence?

In most endings of "Beyond - Two souls", a dream/vision is seen, showing basically

the ghost apocalypse.

During this scene, she says (translated back into English by me):

"I already died twice, I don't fear death."

What does she mean by that? When did this happen? And especially twice? One time might be in the final chapter where the player can decide between

going back into life through the black wall and going to the "other side", through the bright blue one.

But I wouldn't really count that as

dying, since she did not go to the light blue side in the apocalypse dream endings.

So what does she mean and what is the other time?
