On the prescription bottle Mara starts to throw out at the end of the episode, the label says it's for a medication called "Empidonax." However, there is no such drug with that name. It's actually the name of a small flycatcher bird in the Tyrannidae family.
On the Reverie User Interface there were several Latin Words : Domum - Home, Redire - Return, Apertus - Open, Exitus - Exit.
Mara is Hebrew for "bitter" while Marah is Arabic for "joy".
