Whenever Klara arrives at her changing table, she looks up and to the left. She sees something there that makes her very happy. She laughs, makes happy faces, and babbles for as long as we let her, staring at a mysterious interlocutor N and I don’t see. She doesn’t do that anywhere else in the house. It’s just this particular spot between the ceiling and the wall of her room where something very attractive to her but unseen to us is located.
We have arrived at a conclusion that there must be a portal to another dimension in that spot that only Klara has access to.
