The idea of doors appearing and the geometry not quite being right is literally something that has happened in many of my nightmares. And as an elementary school teacher and third parent to a 9 year old, the want to protect Ella was an added layer that has not been in my nightmares yet, but I definitely felt that anxiety. Some of the plot was a little more of a plot device, like why Theo and Ella had to stay for one more night, I will give that. But overall, I liked it.
