My assumption is that when Zoe "woke up" at the beginning of Dreamfall Chapters, she had some memory holes and some memories that she didn't believe were real (of Arcadia), but no false memories. Appearing in Propast and "remembering" moving there would be a false memory. I figure that Propast, the place and people and events, all really happened. At the beginning of DFC, Zoe's attempt to awaken from the coma was half-way successful: she became aware and active in Stark, though as a "solid" projection like in Marcuria. I figure that her being in two places at once was being covered up: Wati, Reza and Gabriel all think that she is really awake and don't know that her comatose body is hidden away somewhere under observation. Falk works for whoever is responsible for the cover-up. (I wonder whether Zoe's IRIS hardware dropped on the couch with the Dreamer, when she phased out.)
Actually, whoever is keeping her body made a room that looks like her hospital room, so Zoe beleives she woke up there, but her body is somewhere else. When she was underground and said she was fading I thought for a moment that it can be due to being at further range from her physical body...maybe not.
I really do think that Reza thinks that she is awake and amnesiac, and that he is monitoring her for WaTi, so if she remembers ha can report to The Eye and bye bye Zoe. So I think Falk and Zelenka are also monitoring her but also protecting her, meaning they know where her real body is.
Problem with that? Zoe has seen Reza visiting her and talking to her body from Storytime...so was he visiting Zoe in Casablanca or where the body is being kept? I mean it's possible, she was on drugs in the first four days and she could be moved...but...umm I dunno
For example, if it becomes corporeal, perhaps Lux cannot then easily 'undream' it; make it non-corporeal. Not that he wouldn't be able to still affect it; just that he might not be able to make it like it never existed.
