I think her real life self is in a coma. shes running out of time would probably be that she is waking up. She needs to find a way to sever the ties of her past and new life
Spoiler :
I will really résumé the hhing if not it'll be really complicated so the humans childrens unhappy have the ability to create their own world in which they can be happy, but superior being are sent to destroy these worlds and kill tje dreamers if i can say lilf that. So Ayrkn invented thus world, little Ayrin jush means that the bad guy will arrive soon ( its the rezl ennemy of thf story)......
No and the onlj to sever the ties she has to die in one of the 2 world but its little more complicated she can't only die would be too easy.....
What did our girl past self mean what she said we’re out of time? And who’s coming for her?
