Predictions?

So i think the Huimin in silence drew those images as a way to cope knowing they could never be happy in that world. So its not because they fortold the future but maybe the drawings is a manifestation of what he wanted and so when they died it became a reality for them. It could explain why time suddenly stopped. Cus the drawings only went so far. And living in this alternate universe only Seo remembers while huimin has no memory. Now after the last drawing happens they were then returned back to the old universe BUT this time the time line is different. Like they are reliving it but still hold the memory. For seo he know the 1st life is real and the 2nd one but huimins brain needs to protect him and so he remembers 1st life as a book and 2nd life as his reality. Idk if maybe im grasping at straws... im a little crazy ╥﹏╥
