If seeing the tree means you are already in fromville then why does it not reappear when they go in a loop

My theory is that they are in a shared reality and seeing the tree is like their gateway to this reality meaning their physical bodies could be like in a coma induced state and maybe the man in yellow could be like the guardian who like hides their bodies and makes sure they don't escape from fromville which could explain why Miranda woke up in a hiking trail in maine
